High-End Product Introduction: PVD Ion Plating Piston Ring
Our PVD ion plating piston ring is manufactured with advanced multi-arc ion plating technology, using vacuum arc discharge as the evaporation source. In a high-vacuum environment, stable arc discharge is formed between cathode targets and the anode chamber. High-energy ions ejected from cathode arc spots form a powerful plasma beam, which reacts with reaction gases under workpiece bias voltage and deposits a dense, uniform coating on the piston ring’s outer surface, mainly including TiN, CrN, ZrN and other super-hard coatings.
This advanced physical vapor deposition process ensures excellent adhesion with high compactness and strong bonding strength, so the coating never peels off under long-term harsh working conditions. The hardness reaches 1800–2500 HV, 4–6 times higher than base materials, fully meeting the demands of heavy-load engines. With a friction coefficient of 0.4, our PVD ion plating piston ring delivers 10× improved wear resistance, greatly extending service life and reducing maintenance costs. Meanwhile, the high-density coating provides outstanding corrosion resistance and stable low friction performance, effectively protecting piston rings and cylinder liners in complex environments.
Backed by professional production equipment and strict quality control, our PVD ion plating piston rings fully reflect Precision Craftsmanship, Technological Leadership. They are widely used in commercial vehicles, construction machinery, high-performance engines and other high-load scenarios, providing reliable sealing and efficient operation for your power system.
