The coloring of titanium is an electrochemical process for surface finishing. Simultaneously the coloring offers the marking of parts and components. Both complete coloring and partly coloring is practicable.
In combination with air titanium builds up an oxide layer on its surface, which extremely increases the corrosion-resistance.
A special procurement removes this layer and builds up a new surface by a galvanical process. The components are treated anodic with direct current in a special acid mixture (“Anodisation”). With it oxygen is emerged that directly combines with the titanium. By adjusting the electrical potential the thickness of the layer can be influenced. The layer’s thickness is significant responsible for the coloring due to light refraction (“Interference-effect”).
Depending on the surface roughness brilliant colors of silver, bronze, blue, gold, pink and green in different color gradiations are possible.
