本文通过高浓渗碳方法,对高碳钢及合金钢,采用不同工艺参数渗碳后的,各种钢渗层表面形成碳化物形态及分布规律进行系统的研究。并对碳化物机理进行了探讨,初步获得细粒状、粒状、块状,分布均匀的碳化物层的工艺方法,为提高工模具的硬度、耐磨性开辟了新的途径。 In this paper, through high-concentration carburizing method, the morphology and distribution of carbides on the surface of various steel infiltrated layers were systematically studied for high carbon steel and alloy steel after carburizing with different process parameters. The carbides mechanism was discussed. The process of obtaining fine granular, granular, massive and evenly distributed carbides was preliminarily studied, which opened up a new way to improve the hardness and wear resistance of the dies.
