如何提高柴油机气缸套和活塞环的使用寿命问题是交通运输部门亟待解决的一个问题。本试验研究针对这一课题,将目前行之有效的几种表面强化工艺——离子氮化、挤渗碳化硅、镀铬——用于气缸套活塞环的表面处理,经常规(磨损机)及中间(台架)的耐磨性对比试验,并考虑到经济、工艺、公害污染等方面的因素,提出了几种可供选配的摩擦副,经对比,认为挤渗碳化硅是一种很有前途的工艺。
How to improve the service life of cylinder liner and piston ring of diesel engine is an urgent problem to be solved in the transportation department. In this study, several surface strengthening technologies, such as ion nitriding, silicon carbide infiltration and chrome plating, were applied to the surface of the cylinder liner piston rings. Conventional (wear) And the middle (bench) abrasion resistance comparison test, and taking into account the economic, technological, pollution and other aspects of pollution, put forward several optional friction pair, by contrast, that is an extruded silicon carbide A very promising craft.
