Wear of Metals in the Lubricating Oil Containing Solid Particles : Effects of Diameter of Partlcles and Contact Pressure

抄録

In the previous paper, the wear tests were carried out in the lubricating oil containing hard abrasive particles, and an equation was derived considering the wear being a phenomenon of plastic fatigue due to rolling contacts of particles. In the present paper, wear tests of some metals are carried out varying the diameter of SiC particles and the contact pressure, and their effects on hardness and roughness of the worn surface and on diameter of wear fragments are studied. The wear rate equation is modified rationally. However, exceptions are observed with very small particles between the mating surfaces and also under the pressure over a fixed value of materials, and the reasons are explained.
