Abstract

A method is proposed to investigate squeeze-induced viscosity enhancement via a nanoindentation technique. A spherical indenter was moved to approach mica and highly oriented pyrolytic graphite specimens immersed in n-Tetracane and water liquids, which are opposite in solid-liquid absorptiveness. Before contact occurred, significant repulsive forces were found to be resulted from enhanced viscosity under squeeze. A Gaussian-like function of viscosity varying with separation was applied to solve the elastohydrodynamics problem. The enhanced viscosity behaviour was found to be strongly related to solid-liquid absorptiveness.
