GRAPHITE EXPANDED AS A FILM-FORMING MATERIAL ON A STEEL SURFACE
Journal Title: Tribologia - Year 2017, Vol 275, Issue 5
Abstract
The results of observational studies of the emerging graphite film on the steel surface are presented. The association – steel pin and graphite element – reciprocating motion was employed. The results show the possible mechanism of graphite film formation for the various stages of association work under various operating conditions. For a water-impregnated graphite element, the film forming process takes place faster than for a dry element.
