Abstract
A novel structured hydrotalcite-based film was synthesized on TC4 titanium alloy by facile hydrothermal method, and then modified with graphene and oleylamine. The structure, morphology, composition, wetting and lubricating properties of the as-prepared films were investigated. The oleylamine/graphene-modified hydrotalcite-based film (HT-OAm/GN) exhibited lower friction coefficient and longer wear life. The enhancement of wear properties was attributed to the synergistic effects of the hard and lubricating graphene layer and oleylamine molecules.
