本文研究了室温形变对钢渗碳、碳氮共渗、离子渗氮过程的影响,并对其中的规律进行了分析,认为位错对间隙原子既有成为通道的促进扩散作用,也有成为陷井的阻碍扩散作用。因处理温度不同,两者会有主次区别,试验结果还表明,为获得复合强化效果,必需正确选择热处理工艺参数。 In this paper, the effects of room temperature deformation on the carburizing, carbonitriding and ion nitriding processes of steel were studied. The regularity of these phenomena was also analyzed. It is believed that the dislocations can promote the diffusion of interstitial atoms as well as the diffusion Obstacles to proliferation. Due to the different treatment temperature, the two will have primary and secondary differences, the test results also show that, in order to obtain the composite strengthening effect, the correct choice of heat treatment process parameters.
