Y2O3对原位自生TiC-TiB2增强镍基复合涂层组织与性能的影响
Effect of Y2O3 on microstructure and properties of in-situ TiC-TiB2 reinforced nickel based composite coating
摘要
Abstract
This paper aims to investigate the effect of adding Y2O3 element on the microstructure and properties of in-situ TiC-TiB2 reinforced nickel based composite coatings by argon arc cladding.The study consists of using Q235 steel as the substrate,preparing a composite coating with in-situ TiC-TiB2 ceramic particles by argon arc cladding method,observing and analyzing the microstructure of the coating by using XRD,metallographic microscope,SEM,and thermodynamic analysis;and testing the hardness and wear resistance of the cladding layer.The experimental results show that adding a certain amount of Y2O3 can promote nucleation rate,among which Y2O3 coating with 0.6%content features the smallest microstruc-ture,along with more and dispersed TiC particles,more refined and uniform coating structure,and the hardness and wear resistance of the coating are greatly improved.关键词
