Extreme-pressure and anti-wear additives

摘要: To understand the nature and function of extreme-pressure anti-wear additives, it is useful to consider again fundamental lubrication by fluids, wear. In an ideal situation, lubricated surfaces are separated a thick film lubricant, all forces between transmitted lubricant. If, for any reason, thickness lubricant decreases, point will be reached such that contact stresses carried increasingly direct solid/solid or, at best, interposed films oflubricant or other materials which so thin they behave as if were solid.
