Boundary lubrication is receiving increased emphasis today, especially with respect to advanced materials. An attempt is made to develop an overall framework to guide developmental efforts. The chemical reaction between the material surface and the lubricant is complex; many reactions occur in parallel between the major elements and their oxides and the minor elements on the surface with lubricant, which usually contain N, O, S, and P compounds. Reaction rates are influenced by surface energy as influenced by rubbing. The reaction products could be inorganic in nature, such as hydrides, nitrides; as well as organic in nature, such as organometallic polymers. These products can act as an effective lubricant as well as exhibiting neutral or detrimental effects on friction/wear. Good lubricating film should have strong adhesion to surface, good lateral bonding to form coherent films, and high shear resistance. Detrimental products usually have high corrositivity such as organic acids, weak surface adhesion, and incoherent film structure.
