Abstract

Effect of carbon nanohorns (CNHs) as additives on tribological properties of self-mated silicon carbide (SiC) in water was investigated. Friction coefficient could decrease with increasing concentration of CNH in water, and minimum friction coefficient of 0.04 was obtained with water containing 1.00 mass% of CNH in severe contact condition. It was found that CNHs form lubricious carbon films on the rubbed surfaces. Formation of carbon film was controlled actively by introduction of laser-surface texturing to substrate, resulting that standard deviation of friction coefficient decreases more than 50% as compared to that without texturing.
