Why Is The Corrosion Resistance Of Titanium Coils Good?

Titanium is a very active metal with a low equilibrium potential and a high tendency to corrode thermodynamically in the medium. But in fact titanium is very stable in many media, such as titanium is corrosion resistant in oxidizing, neutral and weakly reducing media. This is because titanium and oxygen have a great affinity, in the air or oxygen-containing media, the surface of the titanium coil generates a dense layer of good adhesion, inert oxide film, protects the titanium substrate from corrosion. Even due to mechanical wear and tear will soon self-heal or regenerate. This shows that titanium is a strong passivation tendency of the metal. Medium temperature below 315 ℃ titanium oxide film has been maintained this - characteristics.

In order to rise the corrosion resistance of titanium coils, the study of oxidation, plating, plasma spraying, ion nitriding, ion implantation and laser treatment and other surface treatment techniques, the titanium oxide film plays an increased protective effect, and obtain the desired corrosion resistance.
