本文着重介绍了以硼砂为主要成份,三氧化二铬为供铬剂的熔盐渗铬工艺。认为大多数材质零件的渗铬温度为850—1050℃。分别比较了以不同含铬物质为供铬剂组成的渗铬盐浴的特点,对熔盐中影响渗铬的各组分及盐浴成分的控制进行了研究;分别测定了不同材质渗铬层硬度、组
This article focuses on the molten salt chromizing process with borax as the main component and chromium trioxide as the chromium supplying agent. It is assumed that the chromizing temperature of most material parts is 850-1050 ° C. The characteristics of chromizing salt baths with different chromium-containing substances as chromizing agents were compared respectively. The components that affect the chromizing in molten salt and the control of salt bath compositions were studied. The effects of different chromizing layers Hardness, group
