Fracture mechanics study on porosity zirnocia/hydroxyapatite coating obtained through microarc oxidation on medical titanium alloy surface

摘要：

　　In electrolytes TiO2-based complex ceramic coatings containing Ca and P on titanium alloy were ultimately formed containing zirconia/hydroxyapatite by Micro-arc oxidation process.As well as the biomechanics measure experiment of speciments had been done,and the datas were analysised and researched.In addition,the toughening mechanism of reinforced coating was studied in detail,and consists of the second phase toughening,phase transformation toughening and microcrack toughening.The results show that the zirconia/hydroxyapatite coating has advanced biomechanics propertys compared to the individual hydroxyapatite one.
