纺织机械零件因要求的渗层浅(见表),过去都采用液体氰化。但它存在着严重的环境污染问题,必须加以改革。若改用气体渗碳,质量不易控制,为此,我们在井式气体渗碳炉中进行了碳氮共渗,取得了良好的效果。 Textile machinery parts due to the requirements of the seepage shallow (see table), the past are liquid cyanide. However, it poses serious environmental pollution problems and must be reformed. If the switch to gas carburizing, the quality is not easy to control, therefore, we conducted a carbonitriding gas well carburizing furnace, and achieved good results.
