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。

The surface hardness, carburized structure and thickness of the carburized layer on the TiAl-alloy obtained through the different carburization technologies was studied.
试验研究了钛铝基合金离子渗碳后的渗层组织结构、渗碳温度和时间对渗层厚度、 表面硬度的影响。
