TRD CARBIDE COATING  

++

I heard about TRD Carbide Coating onto tools in cold forging and hot forging I would like to know if any body used it on steel and what was the outcome.

Thank you,

You are asking if anyone put them on steel. For what purpose? Is the steel an end product or part of a die or part of a forging tool?

TRD coatings are Vanadium Carbide. I have heard of this coating being tried on die casting dies to increase the lifetime of the dies. The dies are typically made of H13 steel, so the coatings have been deposited on steel. If you are interested in this more I know that Dr. Rajiv Shivpuri in the Dept of Industrial and Systems Engineering, Ohio State University has done the testing of these coatings.

My Company is a representative of Teikuro and the TRD Process. We have worked with this process since the early 1990's.
The process works very well on a carbide mat'l. as well as most tool steels and some hot, or cold roll. Like most coatings the better the substraight the better your tool.
This is an 1800 deg. process so please keep in mind that there can be some draw back to the process.
Here is the short- TRD will not chip peal, or rust it is over twice the hardness of carbide. ideal for fighting wear problems.
