Performance Coatings

The piston(s) is one of the very first parts that should be considered for performance coating. Coating the piston reduces friction and wear (Dry Film), reduces part operating temperature (TBC), can increase horse power and torque, reduce or eliminate detonation, allow higher compression ratios to be utilized and allow tighter piston to wall clearances for a better ring seal.

Pistons can be coated with three different systems. They are Dry Film Lubricants, Thermal Barriers and Oil Shedding Coatings. These systems can be beneficial on all pistons whether 4 stroke or 2 stroke.

Thermal Barrier Coatings (TBC?s) are designed to reduce the diffusion of heat through piston(s) into other engine components. Inside combustion chambers you want to use the heat generated by combustion to push down on the piston rather than penetrate into surrounding surfaces. One and simple way to prevent heat diffusion into surrounding parts is to apply TBC on top of your piston(s).

TBC coatings can be made from a variety of materials. Ceramics get the most attention, though there are other materials that are superior in specific applications.

Dry Film Lubricants, also known as solid film lubricants, provide a lubricating film that reduces friction, inhibits galling and seizing. The appearance is generally gray I color and takes on a sheen upon burnishing. Coating is slippery and provides an extremely low coefficient of friction.

By applying a Dry Film Lubricant, friction, galling and wear is reduced. The lubricants are capable of carrying loads beyond the crush point of the piston. In addition, the lubricants are "fluid retaining" materials that actually hold oil to the surface beyond the pressure where the oil would normally be squeezed off.

Exhaust System Coatings

Black Satin? is the most advanced exhaust system coating available. Withstands 2000 F temperatures.

Exhaust coatings reduce exhaust manifold surface temperature. Improve exhaust gas velocity, increase H.P.
