THE PROCESS OF FORMATION OF THE ADHESIVE CAVITIES UNDER OSCILLATORY MOTION

Journal Title: Tribologia - Year 2018, Vol 279, Issue 3

Abstract

During the direct contact of metal-to-metal, complex tribological wear processes occur. One of the most important and the most problematic phenomena leading to irreversible changes in the geometric structure of the surface is adhesion as a result of a local welding of the asperity peaks. It causes local damage to the surface of the cooperating components in the form of the adhesive cavities. The paper presents the results of the wear tests, the purpose of which was to determine the impact of the surface geometry structure on the process of the adhesive wear and the formation of the adhesive cavities under oscillatory motion. The tests were carried out on the T-05 tribotester based on the previously established research plan. The geometrical surface structure was measured in the area of wear and the photographs of the adhesive cavities were made on an optical microscope. The captured images of a worn surface correspond to the images of the cavities presented in the literature. The obtained research results are the basis for the further development of a future research plan in a similar scope.<br/><br/>
