Electrochemical anodizing treatment to improve the corrosion resistance of commercially pure titanium

摘要

In order to increase the corrosion resistance of commercially pure titanium, anodizing surface treatments were performed by modulating the cell voltage, which controls both the thickness of the oxide film and its morphology Samples were tested with potentiodynamic tests in chlorides and fluorides containing solution in order to determine the pitting potential. Results showed that the anodizing treatment is able to increase the resistance to corrosion, even if no treatments was able to offer the same corrosion resistance of palladium based titanium alloy Based on the results, the best anodizing treatment was selected.
