摘要
A theoretical model for analyzing surface temperature rise between extremely smooth sliding bodies considering the effect of adhesion forces on the contact conditions is developed. The important observation is that in addition to the dependence on load, speed, and material parameters the contact temperature steadily increases with surface adhesion. In the nanometric range of asperity heights contact temperature rise drops to some extent with the increase in roughness whereas in the micro- or macroscale surface roughness, the temperature rise steadily increases with surface roughness. Under certain combinations of load, speed, and material parameters extremely high contact temperature rise is predicted, whereas under certain other parametric combinations extremely low temperature rise may occur. The latter parametric combination is of significant practical importance.
