摘要: Abstract Anodized titanium shows an excellent resistance to pitting corrosion. However, it could be subject failure in case of local removal the oxide film due, for example, incorrect handling during transport, installation, or use. Depending on part size and usage, electrochemical anodizing treatment not feasible. In this case, localized chemical oxidation used recover damaged restore corrosion resistance. Chemical was performed by immersion NaOH 10 M H2O2 at temperature from room 90 °C with duration ranging between 1 h 72 h. Potentiodynamic tests bromides 0.5 M were determine effectiveness relation one obtained anodic oxidation. Higher bath led faster growth film, however has no effect final Breakdown potential increased duration. The establishment a plateau occurs earlier stage, as is increased. Titanium samples anodized then scratched, simulate mechanical removal, recovered using initial restored. suggested treatments in-situ recovery are 72 h exposure 6 h temperature.
