Our PVD Ion Plating Piston Ring is manufactured with advanced multi-arc ion plating technology under high vacuum conditions. Stable arc discharge between cathode and anode generates high-energy plasma, which deposits dense, uniform coatings such as TiN, CrN, ZrN onto the piston ring surface under workpiece bias voltage.
With excellent adhesion and high bonding strength, the coating stays firm without peeling. Hardness reaches 1800–2500 HV, 4–6 times higher than base materials, recognized as a super-hard coating. Friction coefficient is 0.4, delivering 10× improved wear resistance and outstanding corrosion resistance. Ideal for heavy-load engines, construction machinery and commercial vehicles, it greatly extends service life and reduces maintenance costs.

Piston ring is broken what symptom phenomenon does leak have?
The bad piston ring may be related to the air leakage caused by its wear or coke connection with the piston ring groove. If after cutting off a cylinder, the exhaust gas no longer from the oil or vent vent, the cylinder piston is not good use.
