In this study, WC10Co4Cr coatings on the No.45 steel substrate surface have been formed by High Velocity Oxy Fuel （HVOF） spraying. The cavitation and abrasion behavior of coatings and the substrate has been investigated using a self-manufactured rotating disk system. Anti-cavitation and abrasion resistance properties have been illustrated and analyzed with the substrate by the cumulative mass loss curves. WC 10Co4Cr coatings have been used to build up the anti-cavitation and abrasion resistance properties of the main circulating water pump impeller in the nuclear power, and gets good effect.
