通过对氮化和表面渗碳硬化齿轮大量的试验研究,设法揭示对齿轮进行氮化处理的可能性和局限性。
By means of extensive tests on nitrided and case hardened gears, it was attempted to discover the possibilities and the limits of nitriding for gears.
表面碳势为1.1%C的渗碳硬化层内,临近外表面部位的枣核马氏体中会出现显微裂纹。
When carburized under high carbon potential (1. 1% C), microcracks tend to appear on the martensitic matrix near the outer surface of the layer.
淬火:是使渗碳的表面变硬,芯部变得有柔韧性的表面硬化工艺。
Hardening: Case hardening process whereby the carburized outer surface is made hard and strong while the center (core) is made tough and flexible.
