由于密封式淬火炉的出现,碳氮共渗工艺就成为最常用的表面硬化热处理方法之一,这个工艺包括 C 和 N 同时向被处理材料表面的扩散,而这两种元素对渗层的性质有重要的影响。Lucas 电器股份有限公司,在一般新产品的制造中,由于碳氮共渗构件上形成多孔性表面遇到了严重的生产困难,这些困难促使开展下述研究:1.添加 NH_3以及材料成份、予先的冷加工、热处理温度对形成多孔性表面的影响。 Due to the advent of hermetically sealed quenching furnaces, the carbonitriding process has become one of the most commonly used heat treatment methods for surface hardening. This process involves the simultaneous diffusion of C and N to the surface of the material to be treated, and the nature of these two elements Have a significant impact. Lucas Electric Co., Ltd., in the manufacture of new products in general, encountered severe production difficulties due to the formation of porous surfaces on carbonitrided structures, which prompted the following studies: 1. The addition of NH3 and its ingredients Cold working, the effect of heat treatment temperature on the formation of a porous surface.
