摘要：

The aim of the study was to investigate the possibility of calcium and phosphorus ion implantation into an oxide film applied onto titanium during anodic passivation. The corrosion resistance of modified titanium in Tyrode's physiological solution has been identified. Anodic oxidation was carried out in two solutions. The first contained 20 g dm(-3) NaH2PO2 in 4.3 M H3PO4 (K1), whereas the other, 20 g dm(-3) Ca(H2PO2)(2) in 4.3M H3PO4 (K2). Voltage of 100 and 150V was applied. It has been found out that it is possible to incorporate Ca and P into the emerging passive layer. The application of the voltage of 150V makes it very porous. It has been also demonstrated that titanium so modified presents higher resistance to corrosion in the investigated environment than titanium not modified in Tyrode's solution. (C) 2009 Elsevier Ltd.
