Adsorption behavior of sodium carboxylates on iron oxide surface in water and their tribological properties

The tribological performance of sliding surfaces in water can be improved by using lubricating solutions containing additives such as water-soluble sodium carboxylates, which reduce friction and prevent corrosion. These additives adsorb onto metal surfaces to exert their functions; however, the structural characteristics at the metal-solution interface and their influence on tribological properties remain largely unexplored. This paper investigated how water-soluble sodium carboxylates adsorb on
