几年来,上海机械学院金相热处理专业师生,在开门办学中和上海锻压机床三厂等单位工人、技术人员、领导相结合,对用滴注式气体软氮化法提高热压锻模的寿命做了大量试验研究工作,并在生产中应用了滴注式气体软氮化工艺。这项工艺是将甲酰胺或溶有一定数量尿素的甲酰胺直接滴入炉内进行气体软氮化。同其他软氮化一样,此方法能提高零件的 Over the past few years, Shanghai Mechanical Engineering metallurgy heat treatment students and teachers in the open door and Shanghai Forging Machine Tool Plant three units such as workers, technicians, leadership combined with the drip gas soft nitrocarburizing method to improve the hot forging die Life done a lot of experimental work, and in the application of the drip gas nitrocarburizing process. This process is the formamide or dissolved in a certain amount of urea formamide directly into the furnace gas nitrocarburizing. Like other soft nitriding, this method can improve the parts
