To examine the effect of phosphoric acid solution on the anodic oxide film of titanium.
Commercially pure grade 2 titanium specimens were prepared and anodized in phosphoric acid solution at a constant current density (70 A/m2). Specimens were evaluated by means of scanning electron microscopy, x-ray diffraction analysis, electron probe microanalysis, energy-dispersive spectroscopy, profilometry, and atomic force microscopy.
The anodic oxide film was observed to consist of a porous or non-uniform layer and a dense or uniform layer. X-ray diffraction and energy-dispersive spectroscopic analyses indicated that the film consisted of a mixture of anatase and amorphous oxide, with the incorporation of phosphorus.
The degree of oxide crystallinity was observed to increase with an increase in voltage but decreased as the electrolyte concentration was increased. In addition, the concentration of phosphorus also increased as the electrolyte concentration and voltage increased.
Electrolyte concentration and voltage play an important role in governing the anodic oxide thickness, composition, and degree of oxide crystallinity.
研究磷酸溶液对钛阳极氧化膜的影响。
制备商业纯2级钛试样，并在磷酸溶液中以恒定电流密度（70 A/m²）进行阳极氧化。通过扫描电子显微镜、X射线衍射分析、电子探针微分析、能谱分析、轮廓仪和原子力显微镜对试样进行评估。
观察到阳极氧化膜由多孔或不均匀层和致密或均匀层组成。X射线衍射和能谱分析表明，该膜由锐钛矿和非晶氧化物的混合物组成，并含有磷。
观察到氧化膜的结晶度随电压升高而增加，但随电解质浓度增加而降低。此外，磷的浓度也随着电解质浓度和电压的增加而增加。
电解质浓度和电压在控制阳极氧化膜的厚度、组成和氧化膜结晶度方面起着重要作用。
