For the past few years, “Diamond-Like Carbon” (DLC) coatings have been provided to racing engine developers—for Formula One, NASCAR, IndyCar and World Rally Championship vehicles—by the Sorevi Div. of Bekaert (Zulte, Belgium; www.bekaert.com). Now the company has launched a DLC coating called “Dylyn Plus” to reduce friction and increase the wear resistance for the camshafts of high-volume production engines. Tests conducted by Bekaert show an average 15% reduction in camshaft friction losses at common city driving engine speeds, and claims the coating has the lowest coefficient of friction of any commercially available coating. And though camshafts are the initial focus for Dylyn Plus—Bekaert says its Sorevi Div. already has begun coating parts for testing in next-generation V8 production engines—it also can be used on piston rings, valve lifters and gears without harming untreated materials.
