有些零件需要获得很薄的渗碳层,如果采用一般的气体渗碳工艺是很难达到的,这是由于工件在气体渗碳炉中是在气体气氛中加热升温的,边加热边渗碳边扩散,难以使渗层控制到很薄的程度,但是采用真空渗碳,由于工件是在真空中随炉升温,当达到渗碳温度后再通入渗碳气氛,这样可以在最短的时间内使活化 Some parts require a very thin carburized layer, which is difficult to achieve if using a conventional gas carburizing process because the workpiece is heated in a gas atmosphere in a gas carburizing furnace, carburizing while heating Diffusion, it is difficult to control the infiltration layer to a very thin degree, but the use of vacuum carburizing, as the workpiece is heated in a vacuum furnace, when carburizing temperature reached carburizing atmosphere, which can be used in the shortest possible time activation
