Abstract

Abstract: Two stainless steel powders were used to repair the surface of oil damper piston rod by laser cladding with HP-115 five-axis laser additive manufacturing system. The cladding quality, microstructure and microhardness of the stainless steel clad layer were analyzed by means of dye penetrant inspection, OM and microhardness tester. The corrosion resistance of the clad layer was studied by means of salt spray test chamber. The results show that two kinds of the clad layers are of good quality. The thickness of the clad layer and the heat-affected zone is about 0.65 mm and 0.5 mm, respectively. The microstructure of the clad layer mainly includes fine equiaxed and dendritic crystals, coarse cellular crystals and planar crystals. The average microhardness of 12.43%Cr and 16.26%Cr laser clad layers is 729 HV0.3 and 617 HV0.3, respectively, which is significantly improved compared to 250 HV0.3 of the substrate, and the microhardness of stainless steel powder 12.43%Cr laser clad layer meets the hardness requirements of the surface coating of oil damper piston rod. Compared with the substrate, both types of the stainless steel alloy powders laser clad layers have better corrosion resistance.

Key words: laser cladding, stainless steel clad layer, microstructure, microhardness, corrosion resistance
