Research on Cutter of Field Straw Chopper Strengthened with Flame Spray Welding

摘要：

　　In order to solve the high-price and short-lifetime problem of the cutter of field straw chopper, wear-resistance coating was prepared on the substrate of 45# steel by flame spray-welding NiWC alloy.By means of orthogonal test and multiple factors variance analysis, The process that the test factors influence the wear-resistance was studied.The technology parameters of flame spray-welding NiWC alloy were optimized as follows: coating matching, 65%Ni60+35%WC; preheat temperature, 450 ℃; acetylene flow, 1000 L/h; spraying distance,40 mm.
