Coating Fig. 2: Improvement in the specific wear rate and friction coefficient for the nano-tribo-polymeric coating in comparison with currently used products By coating the piston with an optimized nano-tribo coating, the friction between the piston and cylinder skirt is drastically reduced, along with wear. Nano-tribo coatings positively affect the smoothness of the engine, which significantly increases driving comfort. Vibrations are dampened, thus reducing noise emissions and providing a comfortable environment both inside and outside the vehicle.
