当前世界工业的迅速发展,所带来的机械零部件的加重磨损失效,而造成的巨大经济损失,引起了各国的普遍重视。近年来,国家科委和我国许多工业部门,对于本系统所用的易磨损件,先后组织了重点攻关,以提高抗磨件的使用寿命,降低金属材料和能源的消耗;同时,在磨损失效机理的研究和抗磨件的研制方面,都
With the rapid development of the current world industry, the enormous economic losses caused by the aggravated wear and tear of the mechanical parts and components have caused the widespread concern of all countries. In recent years, the State Science and Technology Commission and many industrial departments in our country have organized key research projects on the wear parts used in the system in order to increase the service life of anti-friction parts and reduce the consumption of metal materials and energy. At the same time, Research and development of anti-wear parts, all
