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.
Backed by professional PVD coating equipment and strict quality control, Hearten Auto Parts upholds Precision Craftsmanship, Technological Leadership to provide reliable high end piston ring solutions.
Our Ceramic Titanium Piston Ring uses cutting-edge nano ceramic coating and multi-arc ion plating process. In a high vacuum environment, high-energy plasma reacts and deposits uniformly to form high-performance coatings like TiN, TiC, ZrN, ensuring strong bonding with the substrate.
It features ultra-strong adhesion and high compactness. Hardness reaches 2200–2500 HV, 3–12 times higher than raw materials, classified as a super-hard coating. With friction coefficient 0.4, wear resistance is improved by 150 times, providing outstanding durability under extreme working conditions. The high-density coating also delivers superior corrosion resistance and stable low-friction performance.
Designed for high-performance engines and heavy-duty machinery, our ceramic titanium piston rings combine advanced technology with strict quality control, fully embodying Precision Craftsmanship, Technological Leadership.
Our CKS (CID) Piston Ring adopts upgraded Chromium-based Composite Ceramic technology, an industry breakthrough that meets Euro IV emission standards and delivers double the wear resistance of conventional chrome plating.
The process forms uniform mesh textures inside the outer chrome layer, filled with wear resistant particles to enhance anti-friction performance. The mesh structure also provides excellent oil storage capacity, effectively lowering friction and protecting cylinder liners. The ring body is strengthened by nitriding treatment, boosting hardness, strength and impact resistance.
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.
