Enhancing tribological performance of CBN materials by Fe3O4 nanofluid and wedge-shaped micro-texture considering electroosmosis effect
Nanofluid as cooling and lubrication medium at the micro-textured contact interface is common. It is a promising approach to employ electroosmosis effect to improve the infiltration of nanofluid into the micro-textured interface, thereby enhancing the tribological performance. In this study, the effects of Fe3O4 nanofluids with different surfactant additions on the friction and wear performance of micro-textured specimens were investigated through ball-on-disc friction experiments under self-excited electric fields. Results showed that micro-textured specimens combined with 0.5 vol% sodium lauriminodipropionate (SLI) surfactant exhibited the lowest friction temperature, smallest average friction coefficient, and least ball wear. Moreover, CBN specimen wear was significantly reduced. Combining capillary electroosmosis experiments and tribological test results revealed the penetration mechanism of Fe3O4 nanofluids.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
