Fecha de publicación: | 2015 | Editor: | Elsevier | Citación: | Ceramics International 41(6): 7434-7438 (2015) | Resumen: | In the present work, the dry sliding behavior of a graphene/alumina composite material was studied against alumina in air. The tests were carried out in a reciprocating wear tester with an applied load of 20 N, a sliding speed of 0.06 m s−1 and a sliding distance of up to 10 km. Under the testing conditions, the graphene/ceramic composite showed approximately half the wear rate and a 10% lower friction coefficient than the monolithic alumina. It has been found that this behavior is related to the presence of graphene platelets adhered to the surface of friction that form a self-lubricating layer which provides enough lubrication in order to reduce both wear rate and friction coefficient, as compared to the alumina/alumina tribological system. | URI: | http://hdl.handle.net/10261/137523 | DOI: | 10.1016/j.ceramint.2015.02.061 | Identificadores: | doi: 10.1016/j.ceramint.2015.02.061 issn: 0272-8842 e-issn: 1873-3956 |
