Titanium coating is a coating made of titanium metal

Titanium coating is a technology that applies coatings made of titanium metal or its compounds to the surface of other materials. Titanium coatings typically have excellent corrosion resistance, hardness, and wear resistance, and are widely used in industrial fields such as aviation, automotive, medical, and more.

There are many methods for preparing titanium coatings, including physical vapor deposition, chemical vapor deposition, electrochemical deposition, etc. Among them, physical vapor deposition is one of the widely used preparation methods. In this method, titanium metal or its compounds are evaporated and sprayed onto the surface of the substrate, forming a titanium coating. Chemical vapor deposition is another common method, in which titanium metal or its compounds are heated to high temperature and react with gas to form a titanium coating. Electrochemical deposition is a method of forming a titanium coating on the surface of a substrate through electrochemical reactions.

Titanium coatings have many excellent properties, such as high hardness, good wear resistance, strong corrosion resistance, and high temperature resistance. Titanium coating can also improve the friction coefficient of the substrate surface, reduce surface energy, and increase interfacial adhesion strength. Therefore, titanium coatings are widely used in aviation, automotive, medical and other fields, such as aviation engine blades, automotive wheels, artificial hip joints, etc.
