摘要
The apparent scale effect on friction of single-asperity sliding was investigated with the aid of a molecular dynamics analysis. The specimen material used was mono-crystalline copper, while the asperity materials were diamond and copper, respectively. It was found that a friction transition does exist but depends on interface conditions between the asperity and specimen.
