Single asperity friction in the wear regime
Friction, 2018 We used molecular dynamics simulation to investigate the friction of a single asperity against a rigid substrate, while generating debris. In the low wear regime (i.e., non-linear wear rate dependence on the contact stress, via atom-by-atom attrition ...

Effects of load on tribological properties of B4C and B4C-SiC ceramics sliding against SiC balls
Journal of Asian Ceramic Societies, 2020 Pressureless sintered B4C and B4C-SiC ceramics were subjected to tests of dry sliding against SiC balls at 5 N, 10 N and 20 N. The effects of load on the respective tribological properties of B4C and B4C-SiC ceramics were studied.
