Abstract

Carbonitriding is a case-hardening process sin which carbon and nitrogen are increased in the surface layer of a low-carbon parts at a temperature sufficient to render austenitenic steel. The followed by quenching and tempering to form martensite microstructure. In the comparison with carburizing, Carbonitriding is carried out at a lower temperature, for a shorter time and resultion finer microstructure. However, in our Industry, this method is not developed. The reason that the carbonitriding atmosphere is constituent unreasonably. On this paper, carbonitriding is prepared by mixture of Industrial gas, CO2; N2, NH3, with different ratio. The reasonable ratios is selected. Microstructure, microhardness are tested. This atmosphere is applied for carbonitriding for anchorage wedges, shows good result.

气体碳氮共渗锚固楔的大气成分

碳氮共渗是在低碳零件的表层增加碳和氮，使其在足够的温度下形成奥氏体钢的一种淬火过程。随后进行淬火回火，形成马氏体组织。与渗碳相比，碳氮共渗的温度更低，时间更短，组织更细。然而，在我们的行业中，这种方法还没有发展起来。碳氮共渗气氛组成不合理的原因。本文采用工业气体CO2的混合物制备碳氮共渗;不同比例的N2, NH3。选择合理的比例。测试了显微组织、显微硬度。将该气氛应用于锚楔的碳氮共渗，取得了良好的效果。
