New Mahle piston ring coating for high-output GTDI engines; chromium nitride using high-velocity oxygen fuel process

Green Car Congress

The new top ring coating, also referred to as MSC312, uses chromium nitride applied through a high-velocity oxygen fuel (HVOF) thermal spray process. The market for high-output turbocharged engines is expected to achieve a market share of 30% or more by 2020. It provides the superior performance of a more costly premium inlaid top ring.
