Ceramic Teflon Coated Pistons

Coated piston skirts provide a dry sliding surface for engine startup and feature increased resistance to abrasion and scratching while moving within the engine block.

Ceramic teflon coated pistons.

Power can be lost through heat and friction caused by the motion of the pistons in the cylinders. All ferrous and non ferrous metals. Cerakote v series piston coat is a dark bronze gold with a soft metallic look. There are places that will apply ceramic or some proprietary secret sauce to the crowns but that s a whole nother deal.

For example an uncoated wiseco piston manufactured for a 4 000 inch bore should be installed in a 4 000 inch bore and an armor fit coated piston designed for a 4 000 inch bore should also go into a 4 000 inch bore. In the engine s bottom end dry film lubricants are usually applied to piston skirts engine bearings and the main and rod journals.

Polydyn rp piston skirt coating is a ceramic reinforced dry film lubricant with a low affinity for oil. Je pistons has a wide variety of coatings that cannot be found elsewhere. If measured on top of the armorfit coating the piston to cylinder clearance is less than the uncoated bare piston. Coat the piston skirts with a permanent solid film lubricant.

Teflon coated pistons teflon coated pistons. My application process for how i ceramic coated my d16 s piston tops using vht flameproof paint for my turbo build. You ll find various coatings available for pistons along with other engine parts. Primarily for pistons you ll see ceramic coating of the piston dome to increase heat resistance aka thermal barrier then some go the step further by coating the skirt of the piston with a teflon or teflon like coating to decrease friction.

It is an oven cure ceramic thin film thermal barrier coating designed to be applied on the top of pistons on the top of valves and the combustion chamber on a cylinder head. The coating protects the piston skirt from heat friction and wear resulting in a reduction of parasitic drag while decreasing heat saturation into the piston skirt. The benefit is negligible.
