铝型材热挤压模窄缝硫氮碳共渗

Sulphonitrocaburizing for Narrow Seam of Hot Extruding Die for Fashioned Aluminum

用正交试验和工程平均效应分析方法确定了H13钢铝型材热挤压模的工作面 (俗称“窄缝面”)进行硫氮碳三元共渗的最佳工艺参数。较好地解决了“窄缝面”

Base on orthogonal test and using engineering average effect analysis method,the best process parameters of sulphonitrocarburizing for the H13 steel hot extruding die was determined.And the problems such as noteasy to penetrating for working surface of the die and not uniform of the case are solved.
