摘要:
采用等离子体浸没离子注入和沉积技术(PIII&D),在1Cr18Ni9Ti不锈钢上制备TiN/Ti复合涂层,用X射线光电子能谱仪(XPS)、X衍射(XRD)、俄歇能谱仪(AES)、扫描电镜(SEM)、激光共焦扫描显微镜(LCSM)对大气氛围中在室温、200 ℃和400 ℃的微动磨损特性进行了研究,结果表明:TiN/Ti复合涂层主要有Ti、TiN和Ti2N三种物相,涂层表面层的钛元素主要是以TiN和TiO2的形式存在,涂层与基材之间有一个Ti, N, Fe, Cr元素的过渡层;在部分滑移区,温度对复合涂层的磨损影响不显著,并且涂层的摩擦因数较低,磨损量较小,表现很好的耐磨性;在滑移区,随着温度的升高,复合涂层摩擦因数和磨损体积增加;在400 ℃由于该涂层被磨穿,其磨损体积比基材还大,其磨损机制主要表现为剥层磨损、氧化磨损和磨粒磨损.

Abstract:
TiN/Ti composites were prepared by Plasma Immersion Ion Implantation and Deposition on 1Cr18Ni9Ti stainless steel substrate. Fretting wear tests of the coating and its substrate were carried out under room temperature to 400 ℃ in air. After testing, the morphologies of wear scars were observed by SEM, and very small wear volume were determined by means of Laser Confocal Scanning Microscope (LCSM). Chemical composition and construction analysis of TiN/Ti coating were made by XRD、XPS and AES. The study results show that the composites is consisted of Ti, TiN and Ti2N, TiN and TiO2 in the surface layer, there are Ti, N, Fe, Cr between coating and substrate. In the partial slip regime: The friction coefficient and wear volume of TiN/Ti composition coating were almost invariant with temperature increasing, and the wear volume were quite small, it also exhibited an excellent wear–resistant capability. In the slip regime: The friction coefficient and wear volume increased with temperature. At 400 ℃, as a result of TiN/Ti composition coating wear through, the wear volume is higher than 1Cr18Ni9Ti stainless steel. The wear mechanisms are delamination, oxidation wear and abrasive wear.
Key words:  TiN/Ti composition coatings  high temperature  fretting wear  partial slip regime  slip regime
