Ceramic Coating On Piston Rings

Cermet coated piston rings cermet is a composite part ceramic part metal material.

Ceramic coating on piston rings.

Metal ceramic composite coatings today predominate in most applications as armouring for the running face of piston rings in diesel engines while molybdenum coatings are now only used occasionally because of their comparatively low wear resistance. Ceramic coating when applied to the tops of pistons acts as a reflector of heat minimizing its absorption into the piston diblasi explains. Cks was developed specifically for piston rings in the top groove in highly rated diesel engines. When an uncoated piston is exposed to the extreme heat of combustion that heat can anneal or soften the crown.

Chrome ceramic coating cks galvanic coating main applications. Cks has a crack network filled with aluminum oxide ceramic particles giving significantly lower wear rate and scuff resistance compared to hard chromium. Polydyn ceramic piston coating not only protects the piston but it makes the piston stronger and more efficient by significantly enhancing the structural integrity of the piston dome. A refinement of chrome ceramic coatings goetze diamond coating gdc 50 has proved its excellent wear resistance in large bore eng.

A ceramic coating can also be layered on the piston ring to reduce friction and enhance wear resistance between the ring and the cylinder s inner surface. Ceramic coatings help reduce that effect. Your engine will have increased reliability higher horse power and superior thermal efficiency why spend more money buying new parts protect your old auto parts and save money today. Coatings plating s piston coating will extend your pistons life with more durability reducing piston skirt friction and wear.

Polydyn hs is scientifically formulated to maintain the same coefficient of expansion as the base metal to which it is applied. In summary we can say that the introduction of the chrome ceramic coating in combination with the antipolishing ring marked a milestone in the development of the module piston ring and cylinder sleeve.
