综述了铁基非晶涂层的制备技术、成形特征及显微结构，发现随着喷涂热输入的增大，涂层结构更致密，孔隙率下降，但是涂层中非晶含量降低，含氧量增加。概述了铁基非晶涂层的腐蚀性能、腐蚀行为、磨损机制的进展，并总结了铁基非晶涂层当前的工程应用现状，认为铁基非晶涂层的腐蚀性能取决于涂层化学成分和显微结构的均匀性。非晶含量越高，涂层的耐蚀耐磨性能越好；非晶的孔隙率越低，涂层的耐蚀耐磨性能更优异。但是非晶涂层的点蚀规律及机理尚未形成统一认识。依据非晶涂层的研究现状，提出了非晶涂层在制备、性能及相关机理方面存在的问题，展望了铁基非晶涂层的应用前景。

Fabrication technologies, formation characteristics and microstructure of Fe-based amorphous alloy coatings were reviewed. It could be found that as heat input increased during spraying, coating structure compactness increased and pore density reduced, while amorphous content reduced and oxygen content increased in the coatings. The progress of corrosion property and behavior, wear mechanism and engineering application status of the Fe-based amorphous alloy coatings were summarized. The corrosion property depended on homogeneity of chemical composition and microstructure. The higher the amorphous content was, the better the corrosion resistance and wear resistance were. The lower the amorphous pore density was, the better the corrosion resistance and wear resistance were. However, no common understanding was reached on pitting rule and mechanism of the amorphous coatings. Based upon research status of the amorphous coatings, problems of the coatings in fabrication, properties and relevant mechanism were proposed. Finally, application prospect of the Fe-based amorphous coating was forecast.
