介绍了1Cr11Ni2W2MoV不锈钢在多用炉中低温气体渗碳的方法,解决了该材料低温渗碳层不均匀的问题。结果表明:零件渗碳前经吹砂或磷化,渗碳时通入NH3,能够保证渗碳层均匀。
The method of carburizing 1Cr11Ni2W2MoV stainless steel in low temperature gas in multi-purpose furnace is introduced, which solves the problem of non-uniform carburization of the material at low temperature. The results show that the carburizing layer can be homogenized by blowing blowing or phosphating before carburizing and introducing NH3 during carburizing.
