摘要
介绍了摩擦副无磨损微观模型,用3Cr2W8V模具钢进行热锻模模拟实验,通过在润滑油中添加微细无机矿物粉体以及相应的催化剂,在模压的高温和摩擦磨损作用下,在模具表面在线生成了一层与基体结合力好的氧化物陶瓷涂层,通过扫描电子显微镜对在线修复涂层进行了微观形貌观察和成分分析,同时通过磨损实验发现该涂层可以改善模具的摩擦表面状态,增加耐磨性,提高模具的使用寿命。
Introduce microscopic model of non-wear friction set.Using 3Cr2W8V steel to make a simulation experiment of a hot-forging die,by appending minuteness abio-mineral powder and correspondent catalyst into lubricant,under the function of die pressing high temperature and friction and wear, on mold surface, there is a layer of oxide ceramic coat generated on line,which is well combined with matrix.By means of scanning electron microscope to observe microscopic appearance and to analyze ingredient of on-line self-repairing coat, meantime, through a wear experiment, it is found that the coat may improve die surface friction state, increase wearresistance, and enhance mold's usage life.
