| 摘 要： | 为了改善钛合金表面的生物学性能,试验采用微弧氧化的方法在Ti6A l4V合金的表面生成一层富含Ca和P的生物氧化薄膜.研究了在恒流模式下不同氧化时间对膜层的形貌、厚度、元素以及相的组成变化的影响.研究结果表明:随着氧化时间的增加,膜层逐渐变得凹凸不平;膜厚的增速变缓;Ca质量分数呈线性增长;P质量分数呈递减式增长;锐钛矿TiO2的相对含量先增长,然后逐渐减少.

| Abstract: | To improve biological performance on titanium alloy surface,micro-arc oxidation(MAO) method was used to prepare ceramic oxide layer containing calcium and phosphor on surface of Ti6Al4V alloy.The effects of oxidation time on the surface morphologies,thickness,elements,phase contents of the MAO coatings were investigated when a constant current regime of micro-arc oxidation was applied.The results show that with the increasing of oxidation time,the roughness of the coating surface increases gradually,the gro... |
