Abstract

. In the presented work, the formation of anodic oxide film on Ti-6Al-4V ELI (Extra Low Interstitial) alloy in 0.02 M trisodium phosphate (Na 3 PO 4 ) electrolyte solution using various voltages were investigated. The color produced by the anodizing, the intensity of TiO2 content, the thickness of the oxide layer, and the corrosion rate were examined. It was obtained that the color appearance of Ti-6Al-4V ELI could be changed easily by altering the applied voltages. The higher the voltage applied in the anodizing process, the thicker the titanium oxide layer formed. The corrosion resistance analysis in a Simulated Body Fluid revealed that the non-anodized specimen showed a higher corrosion rate compared to the anodized specimen. The increase of oxide layer thickness leads to a significant decrease in corrosion rate and consequently increases the corrosion resistance. In addition, the anodized sample achieved the highest corrosion resistance at 15 V.

表面涂层对阳极氧化法钛合金骨种植体耐蚀性的影响

．本文研究了Ti-6Al-4V ELI(特低间隙)合金在0.02 M磷酸三钠(na3po4)电解液中不同电压下阳极氧化膜的形成。考察了阳极氧化产生的颜色、TiO2含量强度、氧化层厚度和腐蚀速率。结果表明，通过改变外加电压可以很容易地改变Ti-6Al-4V ELI的外观颜色。阳极氧化过程中施加的电压越高，形成的氧化钛层越厚。在模拟体液中的耐蚀性分析表明，与阳极处理的样品相比，未阳极处理的样品具有更高的腐蚀速率。随着氧化层厚度的增加，腐蚀速率明显降低，从而提高了耐蚀性。此外，阳极处理后的样品在15 V时具有最高的耐腐蚀性。
