采用微弧氧化在钛合金表层生成了含钙和磷的氧化钛薄膜，探讨了电解液组分及电压对薄膜形态、相组成及钙／磷原子比的影响．结果表明；薄膜由锐钛矿 ＴｉＯ２和金红石ＴｉＯ２构成，呈内层致密、外层多孔的形态，且膜中钙／磷原子比由内至外逐渐增大；随电压增大，膜中非晶量增多、孔洞尺寸及钙／磷原子比增大，但有微裂纹呈现；增大电解液钙／磷配比可提高膜中钙／磷原子比．
Titanium dioxide films containing Ca and P on titanium alloy were prepared by micro-arc oxidation. The effect of electrolyte composition and micro-arc voltage
on the phase construction, Ca/P atomic ratio, and morphology of the films were explored. The results show that the films are composed of anatase TiO2 and
rutile TiO2, which appear dense for inner layer and porous for outer layer in morphology. And Ca/P atomic ratios in the films tend to increase from the film/titanium
alloy interface to the surface. The content of amorphous TiO2, size of pores, and Ca/P atomic ratio in the films are increased with increasing micro-arc voltage.
However, the films exhibit micro-cracks at higher micro-arc voltage. Increasing Ca/P ratio of the electrolyte can improve the Ca/P atomic ratio in the films.
