When to use Stellite/Colomony and HVOF Tungsten Carbides?
I have a general question. We have different finishing processes for metals for hardfacing, viz., Stellite or Colmonoy deposition and Tungsten carbide (HVOF) deposition. I have a question when do you employ either one of them? Can they be applied interchangeably or is there any technical issue that is of concern here?

I too would like to know the answer to Mahesha's question.

If you do not have any response, I suggest calling one of the HVOF job-shops.

Stellite is good for shock or impact load. I used to run a mechanical engineering shop. For rough turning where the cut is discontinuous and tool gets punishing impacts, I used to prefer Stellite. For steady cutting, carbides were superior.
