英文摘要	The amorphous coating with composition of (Fe0.5Ni0.2)61Cr9Co6Si1.5B17.5Nb5 was prepared by high velocity oxy fuel (HVOF), and the effects of different heat-treated temperatures and times on the structure, wear and corrosion properties were explored. The structure corresponding properties of coating were analyzed by X-ray diffractometer (XRD), differential scanning calorimetry (DSC), transmission electron microscope (TEM), scanning electron microscope (SEM), wear test machine and electrochemical workstation etc. The results show that with the heat-treated temperatures increasing, the coatings remain amorphous structure, the porosity of the coatings decreases, the oxidation wear and delamination wear of the coatings surface reduce, and the wear scar surface of coating is smoother. The heat-treated amorphous coatings exhibit a wider passive region and low passive current density (Jpass) in the artificial seawater solution, and the wear resistance and corrosion resistance of the amorphous coatings are improved. The FeNi3 nanocrystalline phase appears in the amorphous coating after heat-treatment at 480 for 1110 min. The coating has the lowest porosity of 0.6%, the wear rate of 1.6×10-5 mm3/(Nm), and the lowest self-corroding current density (Jcorr) of 4.591×10-8 A/cm2. © 2022, China Science Publishing & Media Ltd.
