Short-duration gas nitriding of parts made of high-strength cast iron in the GAZ Joint-Stock Company

Castings of high-strength iron are used very widely. The range of automobil e parts cast from iron with globular graphite is widening. It includes cran kshafts and camshafts, flywheels, crankcases, various engine parts, etc. In order to increase the hardness of the surface layer, the wear resistance, and the service life of parts made of high-strength cast iron, they are oft en subjected to nitriding. The present work is aimed at studying the nitrid ing process for parts made of VCh70 and VCh85 high-strength cast iron.
