Hardness testing (Brinell, Vickers and Rockwell test method simply explained)
With the Brinell hardness test, a carbide ball is pressed into the material. The indentation surface serves as a measure of the hardness. Vickers hardness testing is performed in the same way, but it uses a pyramid-shaped indenter made of diamond. In Rockwell hardness testing, the hardness value is determined on the basis of the indentation depth of a diamond cone or a cemented carbide ball. Learn more about these methods in this video.

I haven't created a video about that topic yet but you will find information on heat treatment on my website
May I ask whether uneven surface is suitable for this hardness testing also ? Thank you

I don't think that it is suitable because you don't get valid and comparable results
Great video, very interesting and informative:) what is the name of the machine used?

Thank you very much for the appreciation. I have no idea what machine this is supposed to represent. I looked at some reference pictures and then constructed the whole thing roughly for the 3D animation.

@@tec-science no problem, I suppose these are way out of my budget anyway😅 thanks again for the video!
