Tribology, the study of adhesion, friction, lubrication and wear of materials, occupies an important position in science and technology. It is a multidisciplinary in nature, covering fields of mechanical engineering, rhelogy, chemistry, material science and physics. This volume containing refereed contribution to the three-day international conference on 'Frontiers of Tribology' held in Stratford-upon-Avon in April 1991 is therefore a valuable source of reference for designers, physicists, engineers, researchers and manufacturers interested in latest developments in the field.
