Bearings used in hydrogen technology present significant lubrication challenges. The main difficulty arises from hydrogen molecules being broken down to atoms on the nascent wear sites and permeating steel, leading to failure of tribological parts from hydrogen embrittlement. Lubricant additives that quickly form tribofilms on the wear tracks such as antiwear and extreme pressure additives have proved successful at reducing atomic hydrogen formation and permeation in steel, but their tribofilms increase friction. Nanol™, a sustainable copper-based nanoadditive that forms stable dispersions in oils has unique, friction modifying and antiwear properties. This study used Nanol™ in a polyalphaolefin base oil to lubricate ball and roller bearings undergoing rolling contact fatigue tests in the boundary regime in a hydrogen environment. Apart from the ability of Nanol™ nanoparticles to penetrate the small gaps between moving parts, the nanoadditive also formed cohesive, protective, low friction tribofilms on the wear track. The specific composition and characteristics of the tribofilm played an important role in increasing the fatigue life of the rolling bearings in a hydrogen atmosphere and under severe operating conditions.
