Surface Treatment 1

[Terry62]

I worked as a engineer for the forging industry and came across a technology that will diffuse Titanium into tool steel substrate, H13 @ 46-48 Rc, and produce a 75 Rc surface, .005-.006 deep. This is done to finished, ready for production tooling. Does not change dimension or distort the finish tool.

Do you mean nitriding?

 

[Terry62]

No, I've tried Nitriding and made the tooling brittle. This method is Titanium diffusion. I accomplished this with finished tooling. With Nitriding, had to refit tooling, afterward.

No this process uses Ti in a gas phase (with Cl or F) and hot enough that the gas decomposes on the surface and you form TiC in reaction with C in the bulk alloy. I have done this on alloy cast iron. It does work.
I believe that was Union Carbide Coating Services that did it.

No, Ed this is a liquid bath process, under tempering temperatures of tool steels. This process is done by Philos Technologies in Wheeling, IL. Check out:

It's amazing stuff!!
