无污染盐浴软氮化在内燃机零件上的应用

Application of Non-polluted salt-bath Soft Nitriding in Components of Internal Combustion Engine

无污染盐浴软氮化是一种国外应用广泛的先进工艺。本文介绍了盐浴氮化的发展经历及应用范围 ,重点介绍了上海内燃机研究所在吸收国外先进技术的基础上开发的软氮化盐 ,在曲轴、气门、活塞环等零件上的应用情况。

Introduced development and application scope of salt bath nitriding,especially introduces applicatin of soft nitriding salt in domestic components such as crankshaft,valve and piston ring.The salt is developed by Shanghai Institute of Internal Combustion Engine on basis of foreign advanced techniques.
