Top compression ring: Porous chrome plating / PVD Chromium Nitride / DLC coating. Features excellent wear resistance, oil storage capacity. It seals combustion gas effectively and reduces blow-by gas.

Second compression ring: Nitriding treatment. Improves fatigue resistance and high-temperature tolerance, provides auxiliary gas sealing.

Oil control ring: Molybdenum spraying or nitriding treatment with porous structure. It scrapes excess engine oil from cylinder wall to mitigate oil burning problem.

Ultra-thin and dense coating with extreme hardness, low friction and outstanding high-temperature resistance. It will not damage the cylinder liner. Metallurgical bonding between substrate and surface layer prevents peeling and flaking. It delivers superior performance of high temperature resistance, anti-fatigue property and low friction coefficient.
