The application of PVD coating technology in automotive die-casting products is mainly embodied in the improvement of wear resistance, corrosion resistance and hardness of the products, so as to prolong the service life of the products.PVD coating technology, through the deposition of special functional films under vacuum conditions, endows the coatings with a variety of excellent characteristics, such as abrasion resistance, oxidation resistance, corrosion resistance and self-lubricating properties. This technology plays a vital role in automotive manufacturing, especially in the application of automotive engine components, exhaust systems, etc. It enhances the performance and durability of automobiles by improving the wear resistance and corrosion resistance of these components.
Titanium nitride (TiN) coating and chromium aluminium nitride (CrAlN) coating, etc. These coatings not only have high hardness, high abrasion resistance, high temperature resistance, but also have low coefficient of friction and other characteristics, which makes PVD coating technology in the field of die casting moulds has been widely used.
PVD coating technology is also environmentally friendly, can be processed at lower temperatures, deposited coating material has high hardness, so also has excellent wear resistance, friction resistance and corrosion resistance and other characteristics. These features greatly improve the performance of the surface of the mould cavity in terms of resistance to abrasion and occlusion, making the PVD coating technology one of the main methods to improve the quality of the mould and extend the service life of the mould.
