I show You How I Anodize My Aluminum Parts I Make For My Projects.
Anodizing aluminum is a relatively simple process, although it requires some specialized materials and equipment. Here is a step-by-step guide to anodizing aluminum at home:
Clean the aluminum: The first step is to thoroughly clean the aluminum part you wish to anodize. This can be done using soap and water, or a degreaser if there is oil or grease on the surface. You can also use a solvent such as acetone to clean the surface.
Prepare the anodizing solution: To prepare the anodizing solution, you will need to mix a solution of sulfuric acid and water. The concentration of the sulfuric acid will depend on the desired thickness of the anodized layer. A common ratio is 1 part sulfuric acid to 3 parts water. Be sure to add the acid to the water, and not the other way around, to avoid splashing.
Set up the anodizing bath: The anodizing bath should be set up in a plastic or glass container, as the acid can corrode metal containers. The part to be anodized should be suspended in the bath using a hanger or wire.
Connect the power supply: A power supply is needed to create an electric current that will cause the anodizing process to occur. Connect the positive lead of the power supply to the aluminum part, and the negative lead to a piece of aluminum foil or another conductive material in the bath.
Anodize the aluminum: Once the part is suspended in the anodizing bath and the power supply is connected, turn on the power supply and let the part anodize for the desired length of time. The longer the part is left in the bath, the thicker the anodized layer will be. Typically, anodizing times range from 30 minutes to 2 hours.
Rinse the part: After the part has anodized for the desired length of time, remove it from the bath and rinse it thoroughly with water to remove any remaining acid. Be sure to wear gloves and eye protection during this step.
Color Part If Desired: While the anodizing process is going on, heat your dyes. For most colors, 140° F works best for most colors, but some work better at cooler temperatures. You’ll have to experiment with your brands and colors.
Prepare one tank of distilled water and another with your acid neutralizer.
Seal the anodized layer: The anodized layer can be sealed using a variety of methods, such as boiling the part in water or using a commercial sealer. This step helps to improve the corrosion resistance of the part.
Dry the part: Once the anodized layer has been sealed, the part should be allowed to dry completely before use.
That's it! With these steps, you should be able to successfully anodize aluminum at home. However, it's important to note that anodizing involves working with hazardous chemicals and high voltages, so be sure to take appropriate safety precautions and wear protective gear.

@@abishopish Actually it was done with very fine aeration. These plastic tubes were run through the tank and low pressure air was pumped in. The plastic tube walls were porous, not drilled holes. The bubbles were small, like beer bubbles. It just slowly moved the fluid up one side of the tank so that it circulated in the tank. Once you have established current you don't want to interrupt it until the step is completed.

This video is so awesome I decided to buy my own setup off amazon so I can anodize my AR15 parts. I spent about $200 and all my parts came in yesterday. I am a littler confused tho because research online instructed me to use something called a 720 calculator which tells me to anodize my part at less than an amp. My part is about double the size of the part you anodize in the video. I tried it and it didnt turn out well. I made a mistake somewhere. Ill try again today after work. I may need to anodize for an hour at 3-5 amps. My part is about 8inch by 2.5inch. (AR15 upper receiver) Thx for posting!!

I found personally that if I followed those calculators online for some reason it wouldn't come out good, I don't know if it has to do with location or specific part or the type of water or what, but I always ended up using more voltage and amperage than was stated, once I started just going with my gut then I've had very successful parts. When I was following the online instructions to the t I had many failures.

Whats the thickness off the paint 0.010-0.0012 ?
Can you do a video anodizing green?
The voltage should generally be increasing during the anodizing, not decreasing. I believe the small decrease shown is due to a short-term upset to the bath. If it's consistently dropping you probably connected the wires backwards and are removing any existing anodized layer.
@WarpedLab
3 ай бұрын
Hmmm... You might be thinking of the fact that you have to increase voltage as anodizing layer gets thicker to keep the amperage the same, The anodizing layer is an electrical insulator, have you ever tried the weld a rusty piece of metal, think about it as you have a conductive wire that you add insulation to, as time goes on the insulation gets thicker and thicker and the resistance goes up, amperage goes down And you need more voltage (push) to get the electrons through that insulator.

For better anodizing, the prepared composition (water and acid) can be placed in the refrigerator. The ideal temperature is +1C. Anodizing will be rougher than when using a warm solution.

Lower temperatures allow you to pump more current and / voltage in and let it go for longer amounts of time ala Hard Coat Type III anodize. Theres a bit more to it than that (and colder temperatures), but the main advantage is that the oxide layer can be much thicker and hence tougher. If memory serves ne correct, I thinik I usually get a couple tenths (of an inch - .0002) or so per side of growth doing tyoe 2 and my half ass attempt at hard coat saw closer to a thou (although I was a bit shy). I ended up doing a big ice bath around my tank.

Decorative anodising as shown in the video should be carried out at between 19 and 24 degrees Celsius. Hard anodising is done at between 5 and 0 degrees Celsius. Hard anodising will produce a thicker anodic layer, typically 50% thicker than that of decorative anodising. Decorative produces a much more aesthetically please finished whereas hard produces a more flat finish which is exaggerated after dying the part.
I thought he said in the beginning when fashioning the handling bracket that wherever that touches does not receive anodization ? Or did I misunderstand ? I only ask since it appeared all the threads were anodized.
@burgerfeet101

The point contact from the aluminium wire will be extremely small, it is at this point that no anodising will occur. After dying, you will see tiny spots where the wire touched the thread crest.

@helenavranic1476

Im currently researching aluminum anodization and it says that the concentration should be 10%-15%, so i would recommend buying the already diluted solution. Gonna try to do it myself next week. Buuut if you cant find one with that exact concentration, you can easily dilute it with this equation: c1*v1=c2*v2; c1 is the concentration of the solution that youre diluting (starting solution), c2 is the desired concentration, v1 is the volume of the starting solution and v2 is the amount of destiled water you have to add to the starting solution. Make sure your units of measurements "allign" so c is mol/dm3, so the volume is dm3. Im from croatia and thats how i learned here, but unites can be changed to apply to your preferences!! I hope it helps :)
