Sliding metallic friction with boundary lubrication: An investigation of a simplified friction theory and of the nature of boundary lubrication

Abstract By simply resolving the forces acting at the interface between contacting asperities it is shown that the coefficient of friction is given by μ = tan(α + arctanc) where α is the asperity angle and c is the constant in the linear shear strength-normal pressure relation τ = cn, which is assumed to be applicable to the lubricant film acting at the interface. An experimental investigation of the theory is described. Consideration is given to the nature of the lubrication at asperity contacts using the experimental results as a basis. Finally the simplified friction theory is looked at in terms of the inclined plane model of early friction theories.
