摘　　要：对碳钢表面共渗金属的特点和方法及国内外共渗金属的研究进展情况作了简要介绍。介绍了铝钼共渗钢的抗高温硫、环烷酸的性能和铝钛共渗钢的耐湿硫化氢腐蚀的性能以及两者的焊接性能,阐述了共渗钢的工业应用情况和应用范围。并对共渗钢未来的推广应用作了展望。The characteristics and methodologies of metal diffusion on steel surfaces and the development of metal diffusion technologies both in China and abroad are introduced. The high - temperature sulfur corrosion resistance performance and the naphthenic acid corrosion resistance performance of A1 - Mo diffused steel and resistance to wet H2S corrosion of A1 - Ti diffused steel as well as their weldability are described. The commercial application and scope of application of diffused steels are discussed and outlook of diffused steel application is presented.
