TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
In Phase I, we made prototype sliding bearings from functionally-graded, diamond-coated carbon-fiber reinforced composite. In dry-sliding experiments, the friction of the diamond-coated composites against lunar dust simulant was low and the wear was so small that it could not be detected. In contrast, all other tested materials experienced rapid abrasive wear. These tests demonstrate that diamond-coated composites are ideal materials for non-lubricated bearings, designed to operate in a lunar dust environment. The primary thrust of Phase II will be a fabrication of sliding, journal and ball bearings and testing them in low temperature vacuum chamber that corresponds to the parameters of the Moon's surface. To implement technology transfer, DMI will partner with established bearing companies. Hence, NASA will have qualified suppliers of different types of precision diamond-coated composite bearings.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The bearings that we plan to develop could be utilized for high speed applications at low and high temperatures. They are corrosion and wear resistant and can work in reciprocating and rotary engines as well.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Potential applications of this material are bearings for lunar regolith excavation.
