机械设计制造及其自动化文档,文档编号:JX1004 文档字数:16247.页数:31 摘 要 关键词:离子氮化 软氮化 微观组织形貌 This issue is under study the surface chemistry of carbon steel heat treatment issue, the paper through the surface of the soft-nitride to improve the surface performance. Introduced a soft-nitride and the characteristics of the machinery, and other fields of application, in-depth study of soft-nitride's basic theory, by the end of the soft-nitride equipment and technology requirements. Nitriding of the performance and nitriding of the compound of the composition and the spread of the micro-structure of the closely related. This article also examined the nitride-based soft temperature and nitrogen potential of nitriding layer formation and decomposition of the effects of ion nitriding soft layer of nitride composition and microstructure morphology of the in-depth study. Soft-nitride can contribute significantly to the increase of nitriding of deep, and the types of alloys nitride markedly increased the proliferation of precipitation hardening layer of more small dispersion, will help to improve the quality and nitriding of the workpieces nitriding improve performance. 目 录 iv
