The application of PVD coating in commercial vehicle parts is mainly reflected in the improvement of wear resistance, hardness, corrosion resistance and service life of the parts.PVD coating technology significantly improves the durability and service life of the parts by forming a layer of protective film on the surface of the parts.
(1) improve wear resistance and hardness: PVD coating can significantly improve the hardness of the parts surface, its hardness can be as high as 2000-3500HV (Vickers hardness), far more than many traditional materials. The high hardness gives the coating excellent abrasion resistance, making the parts have a longer service life in the friction and abrasion environment.
(2) good corrosion resistance: PVD film has a dense structure and chemical stability, can effectively block the intrusion of external corrosive media (such as acids, alkalis, salts, etc.), to provide excellent corrosion protection for the workpiece, so that in the humid, corrosive environment can still maintain good performance.
(3) Low coefficient of friction: Some PVD coatings (such as diamond-like coating DLC) have a low coefficient of friction, usually as low as 0.1 or less. This means that friction can be greatly reduced when the workpiece is in motion, reducing energy consumption, improving efficiency and reducing wear caused by friction.
4) High stability: PVD coatings maintain their performance stability in high temperature environments, and some coatings can even withstand high temperatures up to 800-1000°C. This makes it possible to use PVD coatings under high temperature working conditions. This gives it a unique advantage in surface protection of parts under high temperature working conditions.
By improving the wear resistance, hardness, corrosion resistance and high-temperature stability of commercial vehicle parts, PVD coating technology significantly improves the performance and life of the parts, which reduces maintenance costs and improves the overall operational efficiency and safety of commercial vehicles.
