摘　　要：研究了45、T10、GCr15和Cr12MoV钢在硼砂盐浴中的铬钒共渗.采用光学金相、扫描电镜、电子探针和X光衍射等方法研究分析了共渗层的组织结构和性能.结果表明,铬钒共渗层具有高硬度、高抗蚀、高耐磨、抗高温氧化及热疲劳性能良好的特性.讨论了铬钒共渗层形成机理及钒在共渗过程中的催渗作用.This paper deals with Chromvanadizing of steels 45,T10,GCr15 and Cr12MoV in borax salt bath.The structures and properties of chromvanadizing layer are examined and analysed with optical microscope,SEM,EPMA and X-ray diffraction etc.The results show that the chromvanadizing layer has high hardness,high corrosion resistance,high wear resistance,high temperature oxidation proof and better characteristics of thermal fatigue proof.The mechanism of chromvanadizing layer forming and the catalytic effect of vanadium in chromvanadizing are also discussed.
