Large-scale molecular dynamics simulations are applied to study the sliding friction of amorphous silicon carbide on amorphous silicon carbide, amorphous silicon carbide on diamond, nano–crystalline silicon carbide on diamond, and crystalline silicon on diamond systems. The friction coefficient and structural evolution of these systems are investigated as functions of sliding velocity, temperature, and normal load. Based on our results, the physics of atomic-scale sliding friction in crystalline, nanocrystalline, and amorphous materials under investigation is clarified. The established regularities are validated with available experimental results.
