Abstract

The friction behavior of core-shell nanostructure textured surfaces (CSNTSs) was systematically studied using indenters of various tip radii under several normal loads. The effects of the test parameters were investigated on two shell materials to elucidate friction mechanisms. The test parameters, material type, texture uniformity, and deformation had a significant impact on friction values. At the lowest load, adhesion led to the highest coefficient of friction (COF) on both surfaces for all tip sizes tested. At low contact pressures, the Al/diamond-like carbon (DLC) CSNTS experienced a lower COF than the Al/amorphous silicon (a-Si) CSNTS due to DLC has better tribological property than a-Si. At higher contact pressures, more severe deformation and thus higher COF occurred on the Al/DLC CSNTS.
