固体渗碳目前在我国有着广泛的应用,但固体渗碳的主要缺点就是渗碳过程需要极长的时间,因此为了加速渗碳过程,提高劳动生产率,降低处理成本,便有一系列旨在提高固体渗碳剂活性方面的研究。通常的固体渗碳剂是由木炭并加若干碳酸盐(如碳酸钡、碳酸钠等)作为促进剂而组成的,但这种渗碳剂的活性还不够强。据苏联工程师鲁克沙(Л.К.Лукша)对“提高固体渗碳剂活性的方法”—文的研究指出:用加有醋酸钠(CH_3COONa)的木炭作为固体渗碳剂时,其活性要比一般的渗碳剂高,能提高扩散层深度达10％,同时提高表面层的含碳量。我国济南二厂赵燕平 Solid carburizing has a wide range of applications in our country at present. However, the main disadvantage of solid carburizing is that the carburizing process takes an extremely long time. Therefore, in order to accelerate the carburizing process, increase the labor productivity and reduce the processing cost, Research on carburizing activity. The usual solid carburizing agent is composed of charcoal with a number of carbonates (such as barium carbonate, sodium carbonate, etc.) as a promoter, but the activity of this carburizing agent is not strong enough. According to the study of “Improving the activity of solid carburizing agents” by the Soviet engineer Л.К.Лукша, the activity of charcoal with sodium acetate (CH 3 COONa) as a solid carburizing agent Higher than the average carburizing agent, can improve the diffusion layer depth of 10%, while increasing the surface layer of carbon content.
