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. 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. David freiburger explains some of our most popular choices. The benefit is negligible.

Je pistons has a wide variety of coatings that cannot be found elsewhere. By curti march 13 2018 in general discussion. 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. Ceramic coated pistons can assist higher fuel burning efficiency and reduced carbon accumulation which in turn makes detonation more effective.

All ferrous and non ferrous metals. Piston movement also causes scuffing. You ll find various coatings available for pistons along with other engine parts. My application process for how i ceramic coated my d16 s piston tops using vht flameproof paint for my turbo build.

In the engine s bottom end dry film lubricants are usually applied to piston skirts engine bearings and the main and rod journals. Coat the piston skirts with a permanent solid film lubricant. If measured on top of the armorfit coating the piston to cylinder clearance is less than the uncoated bare piston. There are places that will apply ceramic or some proprietary secret sauce to the crowns but that s a whole nother deal.

Power can be lost through heat and friction caused by the motion of the pistons in the cylinders. 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. Piston skirt coating is becoming the norm in the performance racing world and has many benefits. Also follow us on facebook.

On the top side dry film lubricants are sometimes applied to. Link to post share on other sites. 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.
