The application of PVD coatings in gear machining focuses on improving wear resistance, reducing friction and resisting galling of gears. This improves the performance and life of the gear transmission.PVD coating technology provides excellent surface properties by depositing one or more layers of physically vapour deposited films on the gear surface.
1) Improvement of wear resistance: PVD coatings have a high hardness, which significantly improves the wear resistance of gears and reduces damage to gears due to friction and abrasion, thus extending the service life of gears.
(2) Reduce friction and anti-glueing: In high-speed and heavy-duty gear transmission, PVD coating can provide good friction reduction and anti-glueing, reduce direct metal contact between gears, reduce friction and wear, avoid tooth gluing failure, and improve transmission efficiency.
(3) Optimise gear performance: by applying PVD coating on the gear surface, it can improve the transmission performance of gears, especially in the high-speed and heavy-duty working conditions, the PVD coating can effectively protect the gears from damage and maintain the smoothness and accuracy of gear transmission.
In summary, the application of PVD coating technology in gear processing is to optimise the performance and life of gears by improving their wear resistance, friction reduction and anti-glueing properties, ensuring the reliability and efficiency of the gear transmission system.
