I do know of some "near diamond coatings" used on some engine parts. So there is some existing technology they are leaning on. More than likely they were talking to there plater and asking if they had anything special they could do. Lets stuff some scrap parts in with this production batch for something completely different and see what comes out. Pretty rainbow colors like the kids have on the aftermarket exhaust tips.
When I see that rainbow of colors on metal I just think of it being overheated. Welding, I know what the heat affected zone it. My welds tend to be pretty wide, I know some that can make great welds with a tiny HAZ. I can also think of the chrome exhaust tip on the truck after doing a long hard pull up a mountain. Now I know why they sometimes put an air gap between the actual exhaust and the chrome tip.
