Characteristics of titanium nitride aluminide coating PVD coating
TiAlN/AlTiN coatings are characterized by their excellent chemical stability, high temperature oxidation resistance and good lubrication properties, which make them ideal for dry or semi-dry cutting. To be specific:
Chemical stability and high temperature oxidation resistance: The aluminum oxide layer formed in the titanium nitride aluminide coating can effectively improve the high-temperature working life of the tool. This coating can withstand higher temperatures, reducing oxidation and wear of the tool during high-temperature processing, thus extending the service life of the tool.
Lubrication properties: Titanium nitride aluminide coating has good lubrication properties, which helps to improve processing quality, especially in dry cutting. Good lubrication can reduce friction and heat accumulation during processing, protect the tool from wear, and also help to improve the surface quality of the workpiece.
Application: Due to the above characteristics, titanium nitride aluminide coating is mainly used in carbide cutting tools, especially for dry or semi-dry cutting. This coating can improve the performance of tools in various cutting conditions, including high-speed cutting and heavy load cutting, and is widely used in various industrial fields.
To sum up, the PVD coating technology has become an effective means to improve tool performance and extend service life because of its excellent chemical stability, high temperature oxidation resistance and good lubrication properties, especially in dry or semi-dry cutting.
