The Heat of Adsorption of a Boundary Lubricant

Abstract

For the case of physical bonding, the heat of adsorption of a boundary lubricant on a bearing surface has been shown to determine frictional behavior. The theory is here extended to include the effects of temperature and velocity on wear, and corresponding experimental results are presented. The mathematical form of these dependencies is discussed and a characteristic temperature defined and calculated. As a result, a class of very high temperature boundary lubricants is suggested and some further experimental results summarized.
