【摘要】 应用拉曼光谱(Raman)等测试方法分析了不同热处理温度对PVD技术制备的Graphit-iC类石墨碳膜涂层的组织结构、显微硬度、结合强度和磨损率的影响规律。结果表明:随温度升高,涂层发生sp3→sp2结构转变,相对强度比I_D/I_G增加,石墨化倾向增大;涂层磨损率在25～250℃温度区间内保持较低的水平,当温度继续上升后表面显微硬度及结合力降低,磨损率显著增大,耐磨性降低。更多还原

【Abstract】 The effects of heat treatment temperature on microstructure,micro-hardness,wear and adhesion strength of Graphit-iC graphite-like carbon coatings prepared by PVD technique were analyzed by Raman spectroscopy and other test.The results indicated that as temperature increasing, sp3→sp2 phase transition was observed in the coatings and the intensity ratio I_D/I_G increased,and the tendency of graphitization was obvious.The wear rate maintained at low level between the temperature of 25～250℃,although the wear rates of the coatings increased obviously as the temperature increased,the micro-hardness and coating-substrate adhesion strength decreased.更多还原
