The WC-CoCr coating(powder size of 21~50μm and nominal composition of 88wt%WC,8wt%Co,4wt%Cr)were deposited on Inconel617 alloy substrate of sizeΦ30 mm×6mm by PTA-400E1-600V type thermal spraying system.The coating thickness was~500μm.The process parameters of HVOF for the WC-CoCr coatings are as follows:air pressure0.7 MPa,oxygen pressure 1.0 MPa and flow 1100 L/min,propane pressure 0.6 MPa and flow 1100 L/min,powder feeding mode nitrogen feeding powder and powder feeding pressure 0.9 MPa.The chemical composition of the Inconel617 is shown in Table 1.
