Vacuum Titanium Nitride Coating Equipment

General description

Titanium nitride (TiN) plating equipment is a kind of efficient vacuum coating equipment, which can deposit TiN film on the surface of various materials and endow the workpieces with high hardness, low friction coefficient, good chemical inertness and unique color. How it works The working principle of the TiN vacuum multi-arc ion plating machine is based on the multi-arc ion plating technology. The metal vapor generated by cathodic arc discharge is ionized into high-energy ions in the vacuum chamber. These ions are accelerated and bombarded on the surface of the workpiece under the action of the electric field to form the TiN film. The whole coating process is carried out in a vacuum environment to ensure the quality and stability of the coating.

Main components

This vacuum coating equipment is mainly composed of vacuum coating chamber, arc source, vacuum pumping system, bias power supply, control system and so on. The arc source is the key component of the equipment, which is used to produce metal ions; the vacuum pumping station is used to extract the atmosphere in the vacuum coating chamber to ensure the purity of the coating environment; the bias power supply is used to adjust the potential of the workpiece surface, which affects the bombardment energy of ions and the quality of the coating; the control system is responsible for the automatic control and monitoring of the whole coating process.

TiN(Titanium Nitride Coating) is widely used for different applications. The color of it is decorative gold. In functional applications, it is applied on drills and other tools. 
Decorative TiN is used for jewellery, watches, gold mosaics, etc. 
The technology to apply TiN is arc deposition. This process produces a lot of heat. So the base material can be glass, ceramic or metals after pretreatment.

Titanium nitride vacuum coating machine is widely used in surface coating treatment of various tools, molds, hardware products, glass crafts, ceramic crafts and other fields. Titanium nitride thin film has high hardness, low friction coefficient and good chemical inertness, which makes it an ideal choice to improve the service life and appearance of workpieces. In addition, the titanium nitride film also has unique color characteristics, and can be used for manufacturing various workpieces and products with decorative effects.
