Assessment of graphene coatings influence on tribological properties of surfaces

Abstract

This paper presents results of experiments carried out to determine influence of graphene coating on tribological properties of surfaces of friction pairs. Within these experiments series of 24 h tribological tests of sliding friction between examined surfaces on specially designed measuring stand were conducted. Subject of study in these tests were electrolytic copper plated steel samples, additionally covered with graphene and, as a reference, identically prepared samples without the graphene layer. As a result of these experiments characteristics of coefficient of friction and temperature between surfaces, as well as changes in mass and rough-ness before and after tests were obtained. Based on these results improvement of tribological properties of sliding surfaces was shown.
