Federal-Mogul Corporation has developed a piston ring coating, CarboGlide, that supports vehicle manufacturers' efforts to make gasoline engines more fuel efficient.

  • Reduces ring friction by up to 20% compared to nitride or other commonly used coatings to improve fuel economy and CO2 emissions
  • High wear resistance withstands engine's full operational life, even in high-output gasoline engines with turbocharging or direct injection
  • High chemical and physical stability protects cylinder surface from scuffing and scoring, especially under critical lubrication conditions
  • Composition includes multi-layer microstructure and carbon, deposited in diamond-like form, as well as hydrogen and tungsten
  • Can produce coating thickness of 10 microns, more than three times that of industry's latest state-of-the-art DLC coating
  • Is applied via process based on combination of Physical Vapour Deposition and Plasma-Assisted Chemical Vapor Deposition
  • Multi-layer architecture together with surface machining and finishing ensures integrity of coating structure, optimal adhesion and high coating stability
  • Highly stable due to non-metallic nature
  • Combination of low friction, low wear and scuffing resistance allows for application in extreme conditions
