Study on the current-carrying tribological properties of melamine-oleic acid hydrogen bond self-assembled conductive grease
Currently, the conductive grease has problems such as unstable conductivity and large wear volume. This article used an in-situ synthesis method to synthesize a base conductive grease with PAO 10 as base oil, oleic acid and melamine as thickener. The complex conductive grease was further prepared by doping MWCNTs-OH into the base conductive grease. The experiment found that the complex conductive grease's anti-wear and anti-friction properties improved by 72.23 % and 27.16 %, respectively, with respect to the current-carrying condition. The contact resistance is 27.12 % lower than commercially available conductive grease. This method of reducing the contact resistance (ECR) and friction coefficient (COF) of conductive grease through hydrogen bonding shows excellent application prospects in the current-carrying friction direction.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
