HVOF coating over Induction Hardened surface
Hi All

Is it recommendable to do H.V.O.F. coating using std WCCo powder over an Induction hardened surface?

Surface hardness is 60 HRC; but with suitable size abrasive, we are being able to generate a very decent surface roughness of 10 microns Ra

Coating shall need to be ground to 0.3 microns -

Thoughts and suggestion?

I don't think it is a good idea to spray HVOF on this surface. 10 microns is not a lot of roughness for the coating to hold.
