摘要
由于公司应用软氮化热处理的时间不长,工艺不很成熟,加之工人操作不规范,致使软氮化热处理的一次合格率较低,主要是表面化合物层深度不够,表面维氏硬度偏低。往往需要进行第二次补渗才能达到技术要求。为此就须改进现有工艺,提高软氮化热处理的一次合格率。
Because of the relative technology and the abnormal operation,the first percent of pass of elements is low under soft-nitriding heat treatment,which behaves in the inadequate surface depth of compound and the relative low Vickers,hardness.For which the second heating process must be done.Therefore the current process must be improved for upgrading the first percent of pass for soft-nitriding heat treatment,
