Abstract

A Rockwell C 120° diamond indenter with a spherical tip radius of 100 µm was used to measure the coefficient of friction by microscratch test under different normal loads. The measured friction coefficient was found to increase with normal load, which was rationalised by a geometrical intersection model. Although plastic deformation increases with normal load, its contribution into the total deformation becomes smaller with the increase in normal load. Elastic deformation predominates in the total deformation under large normal loads. It is the adhesion shear stress over the contact area that causes plastic deformation. Lateral force was found to be proportional to penetration depth, especially under large normal loads when elastic deformation predominated the deformation, with the proportionality representing deformation or shearing resistant toughness.
