Titanium coating is a technology that applies a coating made of titanium metal or its compounds to the surface of other materials. Titanium coatings usually have excellent corrosion resistance, hardness and wear resistance, and are widely used in industrial fields, such as aviation, automotive, medical and other fields.
There are many methods for preparing titanium coatings, including physical vapor deposition, chemical vapor deposition, and electrochemical deposition. 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 a substrate to form a titanium coating. Chemical vapor deposition is another common method in which titanium metal or its compounds are heated to high temperatures and react with gases to form a titanium coating. Electrochemical deposition is a method of forming a titanium coating on the surface of a substrate through an electrochemical reaction.
Titanium coating has many excellent properties, such as high hardness, good wear resistance, strong corrosion resistance, high temperature resistance, etc. Titanium coating can also improve the friction coefficient of the substrate surface, reduce the surface energy, and improve the interface bonding strength, etc. Therefore, titanium coating is widely used in aviation, automobile, medical and other fields, such as aeroengine blades, automobile hubs, artificial hip joints, etc.
Compare to the traditional electroplating which brings serious pollution, titanium coating process (PVD coating) with barely any pollution becomes more important as environmental protection consciousness gains ground. Titanium coated products gains high hardness, abrasion resistant, easy maintenance and beauty. What's more, PVD coating complies with environmental regulations and such technology is future trends of metal surface finishing all over the world.
Physical Vapor Deposition (PVD) is a method of producing metal-based hard coatings by means of the generation of locally ionized metal vapor, which reacts with a specific gas and forms a thin film with a defined composition on a substrate. The most common methods are sputtering and cathodic arcing. In sputtering, vapor is generated by the bombardment of energetic gas ions on a metal target. The cathodic arc method uses repeated vacuum arc discharges to impact the metal target and evaporate the material.
Among hardware industry, PVD is frequently referred to as Ion Plating (IP). PVD is the technology of using physical way to coat materials onto the substrates in the condition of vacuum.
PVD coatings can reduce long-term costs and increase efficiency. Coating of PVD machine tools can reduce friction and wear, improve product performance and reliability..
