Abstract
THE sliding of one metal surface over another without the occurrence of an undue amount of wear is a problem which arises in every branch of engineering. Successful lubrication and the maintenance of a bearing surface depend upon a wide variety of factors, including those of a mechanical, a metallurgical and a chemical nature. Wear is largely determined by the affinity of one metal for another, the fouling or adhesion of one to the other leading to a roughness; the extent of this roughening and of the consequent wear is determined by the continuity of the film of lubricant separating the two metals, this continuity in turn depending upon the nature of the lubricant and the load it can support without rupture of the film. Our knowledge of lubricated surfaces was extended in 1932 by the work of Parish and Cammen in America, who found that Jelow the film of lubricant there exists a small quantity of oil in the cavities or pores of the
