Abstract

Abstract: Here, we report a uniform and thickness controllable Ti3 C2 -graphene oxide (GO) nanocomposite film on the silicon substrate prepared by electrophoretic deposition (EPD) for the first time. The effects of deposition voltage on the thickness and tribological performance of Ti3 C2 -GO films are investigated. Tribological test results indicate that the nanocomposite film deposited under 35 V exhibites remarkable friction reduction and wear resistance. Namely, the average friction coefficient of Ti3 C2 -GO nanocomposite film is reduced by 76% compared with the bare silicon and the wear volume reduced by 94% and 86%, respectively, compared with GO and Ti3 C2 films. The improved tribological properties of Ti3 C2 -GO nanocomposite films are proposed to be the in-situ formation of tribo-film and the synergy effect between Ti3 C2 and GO. Graphical Abstract: A uniform Ti3 C2 -graphene oxide nanocomposite film was prepared by a facile electrophoretic deposition method and its tribological properties under ambient conditions were systematically investigated. ga1 Highlights: Ti3 C2 -GO nanocomposite films were successfully prepared by a facile electrophoretic deposition (EPD) method. Through the EPD method, high quality films with uniform surface and controllable thickness were obtained. Ti3 C2 -GO film significantly reduced the average friction coefficient and wear volume. The improved tribological properties of Ti3 C2 -GO films are owing to the formation of tribo-film and synergy effect.
