When carburized under high carbon potential (1. 1% C), microcracks tend to appear on the martensitic matrix near the outer surface of the layer.

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。

Hardening: Case hardening process whereby the carburized outer surface is made hard and strong while the center (core) is made tough and flexible.

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。
