THE FORMATION OF SPHERICAL PARTICLES UNDER ABRASIVE CONDITIONS

Abstract

The formation of spherical wear debris was investigated by an analytical ferrograph in different machines. It was stated that the abrasive contamination in gear boxes, I.C. engines and hydraulic systems is a contributor to the generation of spherical particles. According to examinations carried out so far the spherical third body formation can be created through joint plastic deformation of delaminated particles or as a result of forming to supercooled liquid due to the collective effects of state variables.
