空间用9Cr18钢PⅢ复合离子注入表面改性工艺研究
Surface Modification Processes of 9Cr18 for Space Mechanism by Plasma Immersion Ion Implantation
摘要
Abstract
Ti+N ion dual-implantation and co-implantation are used to improve the working surface of 9Crl8 bearing steel by plasma immersion ion implantation(PⅢ) processes.Untreated and PⅢ treated samples were evaluated by the microhardness and vacuum fiction coefficient tests.Wear morphology of surfaces were also evaluated.It has been found that the microhardness of treated samples increases substantially,and the maximum microhardness increases 68.7%,the vacuum friction coefficient decreases from 0.15 to 0.08,the wear scar diameter and roughness are reduced 54.4% and 37.4% respectively.Comparison of the comprehensive properties of different PⅢ process,dualimplantation process is better than co-implantation process under the same condition.关键词
