4 ASPECTS RELATED TO THE OXIDE AND OTHER SURFACE LAYERS 

1 Effect of anodizing and passivation treatments on the corrosion resistance of titanium 

For a detailed description of anodic oxidation of titanium and its alloys the reader may refer to a review by Aladjem (1973). 

The oxide on titanium can grow to thicknesses of the order of 100 nm or more by applying anodic currents in suitable electrolytes. H3PO4 and NaOH baths have been used for this purpose. The colour of the oxide 

F75 Co-Cr-Mo alloy Increased corrosion Accelerated anodic corrosion
