For more than a hundred years, machine parts composed of mechanical carbon have provided an alternative solution in applications where temperature and atmospheric conditions prevent the use of ...

Solid lubrication has become essential in materials science. The first United States patent for these materials was issued in the mid-1940s. 2 Since then, significant progress has been made in the ...

Graphite/metal alloy bearings handle harsh environments that lubricated bearings can’t. For example, a grease-filled ball bearing was used on an oven-door latch—but in tests, the bearing seized and ...

Mechanical carbon machine parts excel where oil-grease lubricants won’t work. Sometimes moving parts go into applications that just can’t risk exposure to petroleum lubricants. Nobody wants grease in ...

Engineers and physicians have made a surprising discovery that offers a target for designing new materials for hip implants that are less susceptible to the joint's normal wear and tear. The team ...

Solid lubricants can be utilized as free-flowing powders, as additives in some oils and greases, and as key ingredients in high-performance anti-friction coatings and anti-seize pastes. These special ...
