内燃机等的发展,对摩擦机件的性能、效率、可靠性及寿命的需求提出越来越高的要求,摩擦磨损与腐蚀的研究受到各国的重视。美国很早就开始用同位素示踪法研究摩擦副的磨损。最初用反应堆中子活化法,此法缺点是放射性较高,工作时需一定屏蔽设备,不适于较大的部件。70年代初,英国哈威尔原子核科学研究中心在工业部门的协作下,首先采用带电粒子表面薄层活化技术,精确地测得各种材料的磨损。西德卡尔斯鲁厄核研究中心开展了许多研究,1980年来上海,A.Gerve博
The development of internal combustion engines and the like has put forward higher and higher requirements on the requirements of the performance, efficiency, reliability and service life of friction parts, and the research on friction, wear and corrosion has drawn the attention of all the countries. The United States has long been using isotope tracing to study the wear of friction pairs. Initially reactor neutron activation method, this method is the disadvantage of higher radioactivity, the work required to be certain shielding equipment, not suitable for larger components. In the early 1970s, Harvard Nuclear Research Center in the United Kingdom in collaboration with the industrial sector, the first use of charged particle surface activation of thin, accurate measurement of various materials wear and tear. Many studies have been conducted at the West Karlsruhe Nuclear Research Center. Since 1980, in Shanghai, A. Gervebo
