Titanium anodized

Titanium is a very promising material. High chemical activity of titanium alloy, highly susceptible to hydrogen and nitrogen pollution at high temperatures. Titanium alloy with low hardness, poor wear resistance, its potential is more positive, contact with other materials can easily lead to contact corrosion, while hydrogen embrittlement, cadmium and other sensitive. 

In order to solve the problems of titanium alloy performance. Titanium alloy surface treatment methods are chemical conversion coating, anodizing, electroplating, thermal diffusion, surface deposition, laser surface treatment and ion implantation. Anodic oxidation and functional coatings are more commonly used.

The color of anodized titanium is due to the difference in the thickness of the oxide layer and the interference with light. The thickness of the oxide layer is affected by the voltage. Different voltage anodized titanium color.
