Friction and Wear of Graphite and Molybdenum Disulphide

Abstract

The reason I gave the name Contact Lubrication to cover the action of lamellar solids is that I do not think they can be fairly classified as boundary lubricants whose adsorptive and film strength properties are indigenious to the lubricant. At best, adsorptive forces provide temporary attachment of particle to sliding surface before the particles are mechanically worked in.
