Abstract

Molecular dynamic simulations have been used to explore the friction between two (110) diamond surfaces in sliding contact. In general, when a third-body hydrocarbon molecule is placed between two computer generated diamond surfaces in sliding contact, the result is a reduction of friction as the load iH increased compared to the same surfaces in the absence of third-body molecules. The size, shape, and alignment of the third-body hydrocarbon molecules play an essential role in the reduction of friction. Results for a system with ethane presented as a third-body molecule will be compared to previous theoretical studies as well as existing experimental data.
