摘要

摘要: 采用化学气相沉积(CVD)技术,在1Cr13不锈钢基体上制备TiC/Ti(C,N)/TiN复合涂层。研究了该涂层从室温(25℃)到400℃的微动磨损特性,并与无涂层的1Cr13不锈钢基材比较。结果表明:在滑移区,温度对1Cr13不锈钢微动磨损影响较显著;随着温度上升1Cr13不锈钢摩擦系数减少,磨损体积下降;而温度对TiC/Ti(C,N)/TiN复合涂层磨损体积影响不大,且磨损量均很小。TiC/Ti(C,N)/TiN涂层表现出比1Cr13不锈钢优异的抗微动磨损性能。但当该涂层被磨去后,产生的硬质磨屑形成磨粒磨损,反而对基体造成更大的损伤。

Abstract: TiC/Ti（C, N）/TiN multi-layer coatings are prepared on the 1Cr13 stainless steel substrate by the technique of Chemical Vapour Deposition, and the fretting wear behaviour of 1Cr13 stainless steel and TiC/Ti（C, N）/TiN coatings are investigated and studied contrastively from 25℃ to 400℃ in the gross slip regime. It showes that the temperature has great influence on the fretting wear in the gross slip regime for the 1Cr13 stainless steel but little for TiC/Ti（C, N）/ TiN multi-layer coatings. With the temperature increasing, the friction coefficient and the wear volume of the 1Cr13 alloy decreases and the wear volume of TiC/Ti（C, N）/TiN multi-layer coatings is invariant. TiC/Ti（C, N）/TiN multi-layer coatings have better wear-resistant capability than the 1Cr13 stainless steel, but the wear volume of the substrate increases greatly because of the grain-abrasion resulted from hard debris when TiC/Ti（C, N）/TiN multi-layer coatings are ground off.
