摘要

Amorphous steel coating with a composition of Fe_(48)Cr_(15)Mo_(14)C_(15)B_6Y_2 was prepared by means of high velocity oxygen fuel (HVOF) thermal spraying. Microstructural analysis gives the information about porosity, oxidation and nanocrystal precipitation. Properties including the hardness, wear, corrosion and magnetic behaviors of the coating were examined. It was shown that the microhardness and wear resistance of the coating are superior to those of electroplated Cr and Ni-based amorphous coating. In 1 M HC1 aqueous solution, the coating demonstrated a low passive current density, a wide passive region and the same transpassive potential as bulk amorphous sample. Furthermore, the coating remained paramagnetic attribute in room temperature.
