固体渗碳有设备简单,投资少,渗碳件表面无氧化脱碳等优越性。因此,即使在先进的工业国家,固体渗碳也没有被其他渗碳方法完全取代,有的还有所发展。在西德,大多数工厂都同时采用固体渗碳和气体渗碳。对固体渗碳的研究也很多,固体渗碳剂由专门厂商供应,其中 Degussa公司生产的固体渗碳剂质量最佳,销售量也最大。另外,在工厂的实际生产中,固体渗碳和气体渗碳工件的质量检查方法完全一样,用同一个国家标准。既要检查渗碳层的深度,也要检查表面含碳量和碳浓度梯度。固体渗碳的生产质量也很稳定。众所周知,评定渗碳件的质量,主要有以下三项技术要求: Solid carburizing equipment is simple, less investment, carburizing the surface of non-oxidative decarbonization and other advantages. Therefore, even in the advanced industrialized countries, solid carburizing has not been completely replaced by other carburizing methods, and some have developed. In West Germany, most plants use both solid carburizing and gas carburizing. There are also many studies on solid carburizing. Solid carburizing agents are supplied by specialized manufacturers. The solid carburizing agent produced by Degussa Company has the best quality and the largest sales volume. In addition, the actual production of the factory, solid carburizing and gas carburizing the quality of the workpiece inspection methods exactly the same, with the same national standards. It is necessary to check the depth of carburized layer, but also check the surface carbon content and carbon concentration gradient. Solid carburizing production quality is also very stable. As we all know, assess the quality of carburized parts, the following three major technical requirements:
