摘要：

For highly improving wear resistance of austenitic stainless steel and extending its application scope, the Ti-C-Fe-Ni powders blend was used as precursor material for in situ synthesizing a wear resistant TiC reinforced composite coating on 1Cr18Ni9Ti austenitic stainless steel substrate by plasma cladding technique. Microstructure of the plasma clad composite coating was analyzed. Microhardness along the depth direction of the coating was tested. Wear and friction behavior of the coating was evaluated under dry sliding wear test condition at room temperature. The results show that the plasma clad TiC reinforced composite coating has a fine and homogeneous microstructure consisting of petal-like and small amount of granular TiC primary dendrites uniformly distributed in the TiC/γ-(Fe, Ni) eutectic matrix. The plasma clad composite coating is metallurgically bonded to the stainless steel substrate. Mean hardness value of the plasma clad composite coating is about 790 HV. The plasma clad TiC/γ-(Fe, Ni) composite coating exhibits excellent wear resistance, low and stable friction coefficient.
