Piston Coating - Antifriction Alternatives
When it comes to piston coating, Embee Performance offers a wide variety of antifriction solutions.
Thermal Dispersant Coatings EPC 100 - This piston coating is similar to hard anodizing. The .002 dimensional change increases piston life and horsepower by evenly controlling part expansion, while reducing friction and part temperature. This coating can be applied to new or used pistons. When applied to new pistons, Embee recommends machining the pistons to allow for the added dimensional change in the ring grooves. However, if machining isn't an option, used pistons can be masked to maintain their current dimensions.
EPC 100MI - This coating process adds a textured crown to the part, while maintaining all the benefits of EPC 100. The texturing on the piston crown helps distribute the impact of the combustion cycle and atomize the fuel for a more even burn.
EPC 100RG - This piston coating eliminates ring welding and ring groove wear, while producing tighter ring tolerances for greater horsepower. This process changes groove tolerances, so manufacturers must allow clearance.
EPC 103 - This coating is aerospace quality hard anodizing. This is the same coating you see on Top Fuel pistons, reducing friction under extreme conditions and excessive wear from high rod angles. Hard anodized pistons can withstand greater temperatures and will not flake, chip or peal.
EPC 107 - This lubricating piston skirt coating reduces friction and inhibits galling and seizing, while adding minimal dimensional change of .0003 to .0005. This piston coating is applied to the skirt area only.
EPC 109 - This piston "skirt saver" coating is specially designed for used pistons. This coating allows for a larger dimensional build-up to correct surface imperfections. The typical dimensional change is .0005 to .001.
