用于改善钢铁表面耐磨、耐蚀、耐热等性能的渗铬方法,已成为重要的化学热处理工艺之一。以卤化盐为基的熔盐渗铬法常需保护气氛。在硼砂熔盐中渗铬及渗其它金属元素的工艺,由日本首先研究成功并取得专利。作者对硼砂熔盐渗金属进行的研究,表明在某些耐磨、耐蚀、耐热零件上应用效果较好。渗铬盐已商品化,具备了推广应用的
The chromizing method used to improve the wear resistance, corrosion resistance, heat resistance and other properties of the steel surface has become one of the important chemical heat treatment processes. Halide salt-based molten salt chromizing often need to protect the atmosphere. Chromium infiltration in the borax molten salt and infiltration of other metal elements of the process, first from Japan successfully studied and patented. The author of borax molten salt infiltration of metals carried out research shows that some wear-resistant, corrosion-resistant, heat-resistant parts of the application is better. Chromium salt has been commercialized, with the promotion and application of
