Near frictionless carbon (NFC) coating, a form of amorphous carbon that has a friction coefficient of less than 0.001 when measured in dry nitrogen, has been developed at the Argonne National Laboratory (ANL). This coating has potentials for many applications including that of naval shipboard. Naval ships contain many systems such as pumps, fans, windlasses, winches, steering gear, reduction gears, door and hatch hinges, elevators and gun mounts, that have rotating and sliding wear surfaces. Currently used lubricants and coatings do not provide long lasting protection against wear and corrosion in marine environment. UES, Inc. and ANL have teamed up for the development of NFC coating using a large area filtered cathodic arc plasma technique and evaluate the coating for performance under simulated marine environment. Near frictionless carbon coating has potential in numerous commercial applications. Examples are: piston rings, gears and bearing components, cams and cam-roller followers, fuel injectors, air conditioning compressors, etc.
