This research aimed to elucidate how adsorbed water influences friction and wear in a ball-onball sliding test. Since the force due to Laplace pressure, FLaplace at the contact interface is the function of relative humidity and surface roughness, they were selected as the manipulated variables in this study. To analyze the role of Laplace pressure, friction and wear at different contact positions were investigated. The empirical tribological results correlate with the theoretical equation of FLaplace developed. Hence, it can be concluded that Laplace pressure is predominant to both friction and wear at low relative humidity and low surface roughness.
