Abstract：Fe-based amorphous alloy coating (Fe49.7Cr18Mn1.9Mo7.4W1.6B15.2C3.8Si2.4Fe) was deposited by AC-HVAF thermal spray on the substrate of 304 stainless steel. By the use of XRD, SEM, Vickers Indenter, and Electrochemical measurements, the structure, hardness, corrosion-resistance, and electrode reaction kinetics of the coating were studied. The corrosion behavior of Fe-based amorphous alloy coating in neutral medium was investigated in comparison with 304 stainless steel. The results indicate that Fe-based amorphous alloy coating has the high content of amorphous phase, homogeneous microstructure, high hardness and good corrosion resistance in sodium chloride solution.
