摘要：
In order to better understand the specific effect of process parameters on porous titanium micro-arc oxidation coating. In this paper, TiO2 membrane layer was prepared on porous titanium matrix with 67 % porosity by microarc oxidation method (MAO), which use a phosphoric acid solution as electrolyte. The samples were characterized using XRD and SEM. The results showed that the samples prepared under the experimental parameters of 350 V and 30 min had a good surface morphology and could provide a higher specific surface area. After soaking in SBF for 7 days, the formation of hydroxyapatite (HA) can be induced, indicating that porous titanium after micro-arc oxidation modification has good biological activity.
