Many micro/nano-electro-mechanical systems have components in relative contact motion. This paper carries out a molecular dynamics analysis to understand how moisture and slider surface roughness influence the friction and wear behaviour of a nano-system. The nano-sliding was between a rough diamond slider and monocrystalline silicon (100) surface with a thin water layer. The TIP4P model was used...
This paper aims to explain the chemical effect on the wear deformation in mono-crystalline silicon components under nano-sliding. With the aid of various microscopy techniques and theoretical modelling, it shows that two-body and three-body contact sliding processes yield the same mechanism of sub-surface damage. For all the sliding conditions studied with normal loads ranging from 147 mN to 441 mN,...
