Microstructure and performance of laser cladding TiB2 and Nickel-coated graphite composite coating on stainless steel 9Cr18
摘要
Abstract
The antiwear and antifriction coating, which contains TiB2 and Nickel-coated graphite, has been obtained on stainless steel 9Cr18 by laser cladding. The processing method, microstructure, interface, microhardness, tribological properties and the forming mechanisms of the coating are analyzed. Results show that the microstructure of the clad coating are mainly long plume-like primary phase sosoloid Ni-Fe which form the matrix framework, while the in-situ anomalous synthetical TiC grains and ultrafine TiB2 grains uniformly disperse among the framework. The hardness and wear resistance of the coating has been greatly improved, which can be attributed to the reinforcement mechanism of TiC, TiB2 , FeC, Fe3C and Cr23 C6. etc. At the same time, the coating has friction-reducing ability.关键词
