一、工艺的改进众所周知,气体氮化最大缺点是处理时间太长,一般都要四、五十小时以上。如何缩短气体氮化的处理时间,而又不降低工件的技术要求,是个令人感兴趣的问题。我们曾进行了一些摸索。下面以具体工件为例,加以说明。1.工件名称:动模板(压铸模上主要零件),见图1。材料3Cr2W8V。 First, the process improvement As we all know, the biggest drawback gas nitriding is the treatment time is too long, generally have four or more than 50 hours. How to shorten the processing time of gas nitriding without reducing the technical requirements of the workpiece is an interesting issue. We had some exploration. The following specific workpiece as an example, to illustrate. 1. Workpiece Name: moving template (die-casting mold on the main parts), shown in Figure 1. Material 3Cr2W8V.
