摘要: Abstract The intrusion process of a C 60 (the smallest ball in nature) into sliding contact space was simulated using the Molecular Dynamics approach. consisted upper and lower Si substrates layered by graphene with an included angle changing from 20° to 90°, just contacted both substrates. A constant horizontal speed 3 nm/ps applied substrate, breaking through observed. During this process, nano-wear substrate evaluated number dropped atoms results showed dependent on initial positions. potential that can control realize no-wear surface revealed, also found.
