  ABSTRACT: The purpose of the present work was to examine in vitro corrosion and bioactivity of surface phytic acid treatment AZ31 magnesium alloys. Untreated AZ31 magnesium alloys were used as control. The surface morphologies of magnesium alloys were observed by SEM. EDS was used to analyze the surface chemical elemental compositions and elemental concentration distribution. Corrosion properties were evaluated by electrochemical tests. Human osteosarcoma MG-63 cells were used to examine cell viability and proliferation. The results showed that surface phytic acid treatment resulted in a surface coating formation, which did not significantly improve the corrosion resistance of the alloys. The corrosion potential of AZ31 magnesium alloy positive shifted only about 0.04 V (from -1.50 V to -1.46 V); and the corrosion current decreased only 0.354 mA/cm2 (from 2.547 × 10-3 mA/cm2 to 2.193 × 10-3 mA/cm2). However, the cell analysis showed that this coating induced obviously higher MG-63 cell viability and proliferation, and displayed good surface bioactivity.
