中文摘要:
      论文采用物理沉积技术在M2高速钢制备多元复合CrTiAlN涂层。采用发射扫描电子显微镜、能谱仪、激光共聚焦扫描显微镜和球-盘式高温摩擦磨损试验机等分析手段对涂层的摩擦学行为进行研究。研究结果表明,涂层的摩擦系数随环境温度升高呈上升趋势。室温下涂层的摩擦系数约0.24,摩擦系数随时间变化曲线平缓;200℃时,摩擦初期涂层的摩擦系数随时间变化波动剧烈,半小时后进入稳定摩擦阶段,摩擦系数在0.53左右。同时,CrTiAlN涂层的磨损率也随环境温度升高呈上升趋势。高温摩擦时,摩擦随时间变化曲线波动很大,对磨球的受磨损程度也随温度升高而逐渐上升。涂层的磨损机制主要是氧化磨损、粘着磨损和磨粒磨损的共同作用。

英文摘要:
      In this paper, the CrTiAlN coating was prepared by physical deposition technology on M2 high speed steel. The tribological behavior and surface morphology of the coatings were studied by means of emission scanning electron microscopy, energy dispersive spectroscopy, confocal scanning microscopy and ball-disc friction and wear testing machine. The results show that the friction coefficient of the coating increases with the increase of ambient temperature. At room temperature, the friction coefficient of the coating is about 0.24 and is gentle with time. At 200℃, the friction coefficient is greatly changed with time at beginning of Friction and then is stably about 0.53 at stable friction stage after half an hour. The wear rate of the CrTiAlN coating also increases with the increase of ambient temperature. The time variation curve of friction fluctuates greatly at high temperature and the wear degree of the grinding ball is gradually increased with the increase of temperature. The wear mechanism of the coating is mainly coordination role of oxidation wear, adhesive wear and abrasive wear.
