The wear resistance of magnesium and its alloys is inherently poor due to their low hardness and tribological properties, which limits their applications. This study aimed to enhance wear resistance by forming a Mg(OH)2 layer on AZ91 magnesium alloy through oxidation in superheated water vapor. A thickness of approximately 25 µm was achieved, and the microstructure and phase composition of the oxidized layer were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD). Additionally, the effect of the oxidized layer on the friction and wear properties of the magnesium alloy was evaluated utilizing a reciprocating friction and wear testing apparatus against bearing steel balls. The results demonstrated that the Mg(OH)2 layer significantly reduced friction coefficients and exhibited minimal wear loss compared to the untreated substrate, indicating its potential as an effective surface treatment for improving the mechanical performance of magnesium alloys. This research supports the further development of protective coatings for magnesium applications in aggressive environments.
