Thermal barrier ceramic-coatings are becoming more common in automotive applications. They are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds, intake manifolds, turbocharger casings, exhaust headers, downpipes and mufflers. This process is also known as “exhaust heat management”. When used in the engine bay, these have the positive effect of reducing engine bay temperatures, therefore lowering the intake air temperature.
It is now common to find on high-performance automobiles and in various race series such as in Formula 1. As well as providing thermal protection, these coatings are also used to prevent physical degradation of the composite due to frictional processes. This is possible because the ceramic material bonds with the composite (instead of merely sticking on the surface with paint), therefore forming a tough coating that doesn’t chip or flake easily.
Although thermal barrier coatings have been applied to exhaust systems, there has been great improvement to internal surface coating; otherwise known as Dry Film Coating.
Dry film ceramic can be applied to any metal-to-metal contact region. It will reduce friction, galling, scuffing only to yield in an increased part life. Contrary to your engine builders thoughts these require no clearance changes to compensate for coating.
Use for crankshafts, eccentric shafts, camshafts, engine bearings, and piston skirts. We will further our list as we provide Alpha Testing to the leading ceramic resin manufacture. Pur kiln can accept parts 27″ wide x 27″ deep x 6′ high so we’re happy to say we can coat “anything.”
