Paper XIII (i) The oxide film and oxide coating on steels under boundary lubrication

This paper measured the P-V diagram of 52100 steel/1045 steel rubbing pair under lubrication with and without oxide coating on the “ball-on-disc” testing machine. The oxide coating was pretreated on the steel surface by heating in the atmosphere of CO 2 gas. The effect of coating thickness and hardness of substrate on the P-V diagram was examined, and an optimum condition had been obtained, by which the load bearing capacity can vbe increased significantly. The microanalyses of oxide film were conducted by AES and XPS as well, and a model of three-sublayer structure of oxide coating had been proposed
