Hi Hemang
In high silt situation HVOF coating of WC done with the given parameters of the equipment suppliers has given poor life of coated Pelton wheel mainly due to poor bonding with CA6NM substrate.HVAF may show better result . Till better solutions have been worked out for such cases. Details you can fish out from my two books on wear(Surface Wear-Analysis, Treatment,and Prevention,ASM-International,2001 a best seller) & on surface engineering(Advanced Thermally Assisted Surface Engineering, Kluwer Academic Publishing,2004).
I am available in USA till end of this month.
