一、前言气体渗碳较固体渗碳有很多众所周知的优点。近三十年来在世界各工业先进国家得到日益广泛的应用,截至目前己经逐渐代替了固体渗碳的地位。我国在第一个五年计划期间,在苏联的无私帮助下很多新建改建的工厂,都陆续的安装了气体一渗碳电炉,初步掌握了气体渗碳工艺,不久的将来这一先进的工艺方法也一定会在 I. Introduction Gas carburizing has many well-known advantages over solid carburizing. Nearly three decades in all countries in the world have been increasingly widely used in industrialized countries, so far has gradually replaced the status of solid carburizing. During the first five-year plan of our country, many newly-built factories under the helpless help of the Soviet Union all installed gas-carburizing furnaces in succession and initially mastered the gas carburizing process. In the near future, this advanced process method It will be there too
