一、引言磨损,长期以来就是工程技术中的一项课题。由于问题的复杂性,大多数的研究只限于简单的系统和零部件的分析。随着复杂、昂贵的现代化机械系统的发展,对这些机器内部零部件在运行中磨损的监测,越来越重要。在内燃机及汽轮机等大型机器中,含有多个不同材料的磨擦界面。这些界面的磨损情况需要监测。目前,尚不能用无损探伤法来监测机械零件的磨损和预报零件的失效。但是,在机器润滑油中的磨粒(磨损的产物)的数量、种类、成份和形貌,是机器磨损情况的鉴证。因此,对含有磨粒的润滑油的分析,会得到有关机器的
First, the introduction of wear and tear, has long been a subject of engineering and technology. Due to the complexity of the problem, most studies are limited to simple system and component analysis. With the development of complex and expensive modern mechanical systems, it is increasingly important to monitor the wear and tear of the internal components of these machines during operation. In internal combustion engines and steam turbines and other large machines, contains a number of different materials friction interface. The wear of these interfaces needs to be monitored. At present, the wear and tear of mechanical parts and the failure of the predicted parts can not be monitored by NDT. However, the amount, type, composition, and topography of the abrasive particles (wear products) in the machine’s lubricant is evidence of machine wear. Therefore, the analysis of lubricants containing abrasive particles, will get the machine
