Ceramic Coating On Piston Rings

When an uncoated piston is exposed to the extreme heat of combustion that heat can anneal or soften the crown.

Ceramic coating on piston rings.

To increase the margin against damage to the piston rings and cylinder liners which will lead to overhaul of the engine on short no tice we have introduced a piston ring configuration that incorporates cermet hard coating on the running side of all the piston rings. Ceramic coatings help reduce that effect. 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. Cks was developed specifically for piston rings in the top groove in highly rated diesel engines.

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. Cks has a crack network filled with aluminum oxide ceramic particles giving significantly lower wear rate and scuff resistance compared to hard chromium. 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. 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.

Coatings plating s piston coating will extend your pistons life with more durability reducing piston skirt friction and wear. A refinement of chrome ceramic coatings goetze diamond coating gdc 50 has proved its excellent wear resistance in large bore eng. 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. Polydyn hs is scientifically formulated to maintain the same coefficient of expansion as the base metal to which it is applied.
