Some Aspects of the Thermal Desorption of a Boundary Lubricant

Abstract

An expression is developed relating friction coefficient in a boundary lubricated sliding system to temperature, heat of adsorption, and sliding velocity. Frictional and wear phenomena are shown to be double exponential functions of temperature and single exponential functions of sliding velocity. Experimental confirmation is obtained and a simple method is indicated for measuring the heat of a adsorption as a function of temperature.
