摘要：

A wear resistant (Cr,Fe)7C3/γ-Fe ceramal composite coating was fabricated on substrate of a 0.45% C carbon steel by plasma transferred arc (PTA) cladding process using the Fe-Cr-C elemental powder blends. The microstructure, microhardness and dry sliding wear resistance of the coat- ing were evaluated. Results indicate that the plasma transferred arc clad ceramal composite coat- ing has a rapidly solidified microstructure consisting of' blocky primary (Cr,Fe)7C3 and the inter- blocky (Cr,Fe)7C3/γ-Fe eutectics and is metallurgically bonded to the 0.45%C carbon steel sub- strate. The ceramal composite coating has high hardness and excellent wear resistance under dry sliding wear test condition.
