在近代发动机向着高转速、高负荷的强化方向发展的同时,活塞环经受了更严酷的工况考验,原结构、原材料的活塞环在使用中发生了一系列新的故障。为解决这些问题,在党的领导下,广大工人、知识分予和干部相结合,“自力更生、艰苦奋斗、破除迷信、解放思想”,从实践中创造了许多新材料新工艺。其中对于活塞环的强度和耐磨损性能方面,除对活塞环的材料选择、加工工艺和结构设计方面
In the modern engine toward high speed, high load direction of strengthening at the same time, the piston ring has suffered a more severe test of the conditions, the original structure, the raw material of the piston ring in the use of a series of new failures. In order to solve these problems, under the leadership of the party, a large number of workers and intellectuals are given a combination of cadres and “self-reliance, hard work, superstitious beliefs and emancipation of the mind” have created many new materials and new techniques in practice. Among them, the strength and wear resistance of the piston ring, in addition to the piston ring material selection, processing and structural design aspects
