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

Abstract:

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 °C; acetylene flow, 1000 L/h; spraying distance,40 mm.
