Anodisation Type III Colouring of osteosynthesis product surfaces - DOT GmbH

Type III Anodisation (Colouring)


The anodisation type III (colouring) is performed in diluted acid. The titanium oxide film that is produced works as an optical interference filter. By varying the thickness of the coating all the colours of the rainbow can be produced. The standard colours produced are red, blue, yellow and green. Customers can also select from a larger range of colours.
