摘要

The high corrosion susceptibility of biomedical magnesium alloy has become a practical problem which restricts its orthopedic application. To enhance its surface properties, PHPS-derived coatings were fabricated on the surface of AZ31B magnesium alloy using a simple polymeric precursor method. The resulting thin coating, about 2 μm thick, possessed a dense surface structure and had an adhesion strength of 4B. The effect of different curing temperatures on the coating composition, corrosion resistance and biocompatibility was systematically investigated. The coating cured at 200–300 °C showed the best corrosion resistance in a phosphate-buffered saline solution, providing good protection for magnesium alloy with a degradation rate about 10% of that of bare alloy. Cytotoxicity tests indicated that the coatings enabled higher cell viability compared to uncoated samples. These findings advance the understanding of the service performance of PHPS-derived coating in corrosive environments and support the broader application of magnesium alloys in biomedical fields.
