【 摘 要 】

Ti6Al4V is one of the commonly used orthopedic metallic materials, but its bioactivity is weak, which makes it challenging to produce bone integration between material and bone tissue. In this study, an Mg/SrP composite coating was prepared on Ti6Al4V, to promote bone tissue healing and shorten the healing cycle. The surface characterization, in vitro degradation performance and bioactivity of the composite coating, were investigated. The results revealed that Mg/SrP composite coating has more suitable degradation rate than Pure Mg, no cytotoxicity was found on the Mg/SrP composite coated samples, higher proliferation compared with the culture medium was found, indicating that the Mg/SrP composite coating is a candidate coating on Ti6Al4V to improve the bioactivity.
