The Phosphate bit reminded me of the Phosphorous (*not* Phosphoric) Acid treatment some painters do to sheet metal. Or, let the part 'flash rust' then convert iron oxide into iron phosphate, aka "hard porous salty layer" which then absorbs most liquids into that layer (be that oil or paint). Texture seems to be the same, color is dull light grey tho, not dark/black.

All of the Parkerized finishes I've seen on old military rifles (M1 Garand and M1 carbine) have has the flat finish but with a greenish tinge. For 70 year old rifles, the rust resistance has been very good. A light wipe down with an oily rag followed by a dry rag might also help.

I have tried using cold bluing solutions and they look good for a few months but the corrosion soon sets in. All the tools that I have parkerised still look as good as the day they were done.

It does take a while to get all the liquids up to temperature though. Hawaii would have a very similar climate to where I live. We spent a few days in Kauai and the climate felt very familiar to us.

I live in southern Canada, its quite humid here in the summer. When I built my shop I installed ceiling fans. They act to keep the air moving in the shop so condensation doesn't collect on equipment.

I found an old socket that had been trod into the (dirt) floor of the shop. I threw it into an old coffee container full of vinegar ... missed it when I pulled other parts out, then went on the road for 10 days, then spaced it for two or three more. Remembered it when I moved the container and heard it scooting around. Between the rust and the prolonged vinegar soak, it pitted drastically, but it hasn't showed any sign of rusting again. The patina is very much like what you got here, very much like an impact wrench socket. It sits on the bench, being used for anything except as a socket. I know Randy Richard did some bluing with a method that used vinegar, but that was a long process, best for those with more time than money.

Diggerop, I have used the electrolytic method for rust removal using washing soda and a stainless steel anode and it gives a similar finish and as you say it resists rust well afterwards. Maybe all those methods create a similar oxide layer. It was the texture on the parkerised finish that I was impressed with. It was hard to show on camera but it really did look like it had been bead blasted. Probably off topic but I had made some parts for a model steam locomotive from bright mild steel and I polished them with emery cloth and after a few days they had a rust patina on them. I was very disappointed but went through the polishing process a second time and they are still bright and rust free many years later. I am wondering if the initial corrosion creates a skin of some kind that protects the underlying steel? Regards, Mark Presling

Interesting I'll be looking for the follow up

My guess as to why the finish feels slightly rough is the treatment just before the Parkerizing must have etched the metal to make it more porous for adhesion of phosphate. Looks like the black oxide coatings on tools that aren't chromed. Looking forward to the follow-up.

@Preso58

I think the activator is actually phosphoric acid but I cannot find any information about this. It certainly appears that there is an etching action before it goes into the parker phosphate. Having said that, it also appears that there is a lot of fizzing going on when the steel is in the parker solution as well. I have 6 samples sitting out on the bench at the moment and I will be leaving them there for nearly 7 weeks so I am keen to see how they hold up during that time. Stay tuned for the results.

I'd recommend to oil it down with mineral oil, and let it soak into the parkerization. Water soluble oil is good to halt the process, but for real rust protection long term you need to add that second oil barrier. I am also in a sub-tropical climate (Florida) and know what a job it is to keep things rust free. Mineral oil (with a bit of liquid lanolin if near the beach) has worked very well for me, and is cheap. 3-in-1 is also very good, if it's available in your country.

Straight mineral oil keeps rust away from my anvil which is stored in a non-climate controlled shop with a leaky roof, in Florida. How's that for effective? You can also thin the mix with mineral spirits, if you want a lighter coating that will still protect, but it will need refreshed a little more often. I use the thinned stuff on tools that get a lot of use, just wipe them down with a mineral oil wetted rag after using them. Handy tip: mineral oil also works amazing on firearms, and doesn't react negatively with black powder residue, so is really good to keep those old muzzle loaders rust-free in the bore. :) Mineral oil (light coat) in the breech and barrel, 3-in-1 inside the works, and you're GTG.

When I was teaching we would always rub floor wax on the chisels and plane soles before the 6 week summer holiday and they resisted rust well. It really is just a case of ongoing maintenance. Something I am not good at unfortunately. Regards, Mark

Nice tap holder setup Mark! Can I ask what size thread you'd be comfortable holding onto with that?

I think it might handle up to 14mm metric coarse but in most cases I just want to get the tap started concentric to the lathe axis. When the tap starts to slip in the chuck I can swap over to a standard tap wrench. Having the tap slip is a good way of avoiding broken taps! Regards, Mark Presling

Aren't you supposed to sandblast parts before you parkerize? Never seen a polished piece go in like that but it turned out awesome.

@Preso58

I usually just ensure the parts are chemically clean. The texture that you end up with after using the Jane Kits solution is very much like sand or bead blasting but it is done entirely by the etching action of the phosphate solution. I guess that having a sand blasted finish to start with helps to increase the surface area so maybe it just reacts quicker. Regards, Mark

My 1903 Springfield rifle, Parkerized, absorbed so much Cosmoline over its decades in government storage that it took on an olive green hue. Blued (smooth) or Parkerized (texture) they must be oiled regularly.

I have had good parkerizing results using Turco rust converter. First I clean most of the loose scale off with sandpaper. then there are 2 different methods to use. 1. Is to use a toothbrush, wear rubber gloves, and dip the brush into the turco, and scrub vigoriously for 15-20 min. depending on part size and amount of scale on the metal. It WILL remove mill scale. Eventually you will get a nice even greay finish, which then you rinse with clean water, dry well, and coat with wax. I use a cheap floor wax which seems to be merely kerosene and paraffin. 2 this method is more expensive to set up, but better for production. get yourself a largish ultrasonic cleaner. hen a second smaller plastic container to fit in the ultrasonic cleaner. This is because Turco will react with the stainless in the cleaner. Fill the plastic container with turco, place in the ultrasonic cleaner. pour some water around the outside of the cleaner but inside the stainless tub. this will transmit the vibration from the machine thru the water and into the turco. then just clean away with the ultrasonic cleaner until a nice finish is achieved.

Daniel, I didn't parkerise the guide rod or the MT3 taper and I noticed a slightly better fit after the bore of the tapping spindle was done. I suspect that the roughness of the parkerised finish would soon be rubbed off so it might appear to be tight to start with. I am planning to do the guide rod later so I will try to follow up at a later date. Regards, Mark

Not that I could measure. Parkerising is often used on cam shafts after grinding so that they hold an oil film better. I would think that if the parkerised finish changed the diameter of the journals it would be a problem. The process mostly etches the surface so it becomes sort of porous. It's not really and additive coating. Regards, Mark

I have been thinking about that myself. I wanted to parkerise just the morse taper of the shank that the tap holder runs on and I was thinking that I might be able to mask it off with heat shrink tubing. I did parekerise a tool made from chrome plated 4140 hydraulic piston rod. Most of the part was machined but some of the original chrome was left on. The parker phosphate completely blackened the machined areas but the chrome was unaffected. It actually looks great. I guess you could copper plate or zinc plate some areas but it seems like a lot of extra work. Regards, Mark Presling

I would love to see a quick follow up video on this now that it has been a couple of years.

I intend doing that but I can tell you that all the parts I have treated with the parker phosphate are still as good as when I processed them. Items that I have cold blued and left out in the workshop are mostly corroded. I did some cold blued parts that were stored in a closed box and they are still mostly black and corrosion free though. Regards, Mark

If you leave parts in a the phosphate for to long crystals will form on the surface, a good test to see if the process is adequate is to wipe the part with a damp white cloth before the oil step and if the rag is clean then the finish had adhered corectly and if not the part then needs longer in the phosphate solution, also lower carbon steels give light colours so a 4140 will give almost a black finish in my experience and manganese phosphate will produce a darker thicker coating then say zinc phosphate

Braden, I did a piece of 4140 the other day and it came out a nice dark charcoal. It was a tool made from some chrome plated hydraulic piston rod and part of the chrome outer surface was left on the part. The parker phosphate didn't touch the chrome at all which proves that it only works on ferrous stock. So far all the parts I have done seem to be very durable and the coating seems quite tough. I have done some sample pieces to try to get a handle on what the best after treatments are and I did a piece which I want to deliberately abrade to see how thick the coat is. I will have some results when I return from my holiday in 6 weeks. Regards, Preso

Mild steel will never go as black as a hardenable steel with some % carbon in it. There's even a difference in color between high carbon steel thats been hardened and unhardened high carbon steel. The reason gun parts will go very black when parkerised is because most of the parts contain a higher carbon %.

I expect any chemical process involving conversion like this will result in, at best, a fine blasted surface effect as the process changes the parent material surface structure.

One of the benefits of the Nitriding processes which have superseded Parkerizing in the firearms industry is that they affect the metal fairly deeply, yet change the surface dimensions and texture almost not at all. Functionally nitriding is superior, but park has its place. Parkerizing adds a slight increase in surface hardness which protects against scratches, and very very slight corrosion resistance. To gunsmiths, it primarily serves as a good way to make oil or paint stay where you need it. Anywhere the parkerizing gets polished off by function is rubbing enough to keep itself bright anyway. Nitriding on the other hand is a lot harder, and can make a file skate on a fairly soft steel. It is corrosion resistant enough to be better than stainless, and doesn't need paint or oil to work. You might notice that the grade 10 fasteners are often black... That's a nitride finish. On our commercial fishing boat, I noticed that even in the salty bilge, nitrided bolts often stayed unchanged for decades, whereas the steel they are in is invariably rusty.

@@Preso58 Thanks for the info Mark. I think I'll get myself a kit. I have used the cold blueing and that works OK, but as you found it is decorative only. For parts like the toolpost on my lathe that is a good solution as I always oil every surface when I'm finished with it. It also doesn't change the part dimensionally and it doesn't change the surface finish. For things like tools or parts of machinery that need real rust protection, I'll give parkerising a go. Thank for all the great videos mate, they're well put together and a real joy to watch.

Looks nice Mark. I must confess to skimming through your video a bit (always short on time) but did you say there is any improvement in hardness or wear resistance? Wouldn't a cold case hardening chemical be so handy! Cheers, Cliff

@Preso58

Cliff, it doesn't really harden the surface but it does improve "lubricity" which is the ability to carry oil and therefore reduce friction. I believe that camshafts are often parkerised after grinding to reduce wear. One thing that I have noticed is that closely fitting parts will "grow" slightly after parkerising but I usually remove the parkerised coating on any surfaces that need to fit. I primarily use it as a rust preventative treatment and it's ideal for that. If you do find a cold case hardening compound I'm in! Regards, Mark

If you instead of removing the rust, just boil the part in distilled water for about 15min. That will transform the red rust to black rust, which practially is the rust bluening you see on older firearms. Anyway, Parkerizing is a very good, if not better option.

The texture is probably because it's zinc phosphate. If it were Magnesium phosphate it would be black. Zinc molecules are fairly large intent to leave a discernible text your to anyting you apply the phosphate coating to. An application of Z Max or Marvel Mystery Oil would seal that up quite nicely.

Chuck, my shop is just a steel shed and only the roof is insulated. The walls don't seal against the roof sheets and there are three roladoors with large gaps above each one. When we get our wet season the humidity and moisture gets in to the shop very easily. I usually leave one of the doors open on fine days so as to keep some ventilation going but I had not considered a roof ventilator. I guess if I were more disciplined I would clean my tools more often. Regards, Mark Presling
