摘　　要：探讨了5CrMnMo 钢在添加适当的还原剂、活化剂的硼砂和氧化铝熔盐中,于临界点以下的硼铝共渗.结果表明,在临界点以下,硼铝原子可以在铁素体中共同扩散,形成由铁硼化物和铁铝相组成的共渗层.试件的变形很小.This paper probes the boronaluminiuming technique of 5CrMnMo steel by the fused salts composed of boraxs and aluminium oxide powders and addied reducing agent and activator below critical temperature.The result shows that,the boron atoms and the aluminium atoms can codiffusing into ferrite,so that obtained the codiffused layers with FeB chemical compounds and FeAl phases,and the deformation of the samples is very small.
