Use of Zinc Oxide Nanopowder as an Additive in a Tribotechnical Composite Based on Refractory Metal Disulfide

Abstract:

Tribological properties of a composite mixture based on zinc oxide nanoparticles and nanolamellar tungsten and molybdenum disulfide powders have been studied. XRD and TEM of ZnO nanoparticles produced by electric discharge of metallic granules in an H₂O₂ solution were analyzed. The tribological tests showed ZnO nanoparticles additive in metal disulfide powders did not practically change the friction coefficient in comparison with pure WS₂ and MoS₂ powders at 25 °C in air. At 400 °C zinc oxide nanoparticles in composite lubricants positively affect the wear resistance.
