本文介绍了3Cr2W8V 模具表面合金化的工艺试验情况(这里主要指的是渗钨、铬)。作者通过在固体渗碳剂中和在三乙醇胺裂解气氛中合金化的试验指出:在固体渗碳剂中合金化,渗层可达0.6～1.0毫米,在三乙醇胺裂解气氛中合金化,渗层可达1.35～1.5毫米而渗层均匀。渗层硬度可达 HRc68—70,变形仅在0.005～0.02毫米范围内。作者通过试验推荐合金化配方为:钨酸铵80%,碳酸铬20%。
This article describes the 3Cr2W8V mold surface alloying process test conditions (mainly refers to the infiltration of tungsten, chromium). The authors test by alloying in a solid carburizing agent and in a triethanolamine cracking atmosphere indicates that the alloying in a solid carburizing agent can reach 0.6 to 1.0 mm in the infiltrated layer and is alloyed in a triethanolamine cracking atmosphere and the infiltrated layer Up to 1.35 ~ 1.5 mm and infiltration layer even. Layer hardness up to HRc68-70, the deformation is only 0.005 ~ 0.02 mm range. The authors recommend that the alloying recipe is 80% ammonium tungstate and 20% chromium carbonate.
