| 摘 要： | 为获取H13钢挤压模具表面硬化最佳工艺参数,采用氮硫气体软氮化工艺,通过正交试验设计,进行了29次现场试验。研究分析各组试样金相组织、显微硬度和渗层厚度,优选出1组适合铝合金型材H13钢挤压模具表面硬化处理的最佳工艺参数并应用于生产,按此最佳工艺参数硬化处理后的挤压模具表面硬度达到1 100HV0.2,单模型材通过量比以往提高3倍多,优选工艺参数完全适合于H13钢挤压模具表面硬化处理。

| Abstract: | In order to obtain the optimal parameters of surface hardening process of H13 steel extrusion die,the soft-nitriding process of sulfur-nitrogen was adopted.Through orthogonal experiment design,29 field tests were conducted.A group of optimal process parameters of surface hardening was selected for the H13 steel extrusion die by analyzing the microstructure,microhardness and nitrided layer thickness of specimens.And the optimal parameters were applied in mass production.The surface hardness of aluminum alloy... |
