Increasing Wear Resistance of Heavy-Loaded Friction Pairs by Nanoparticles in Conventional Lubricants: A Proof of Concept

This paper provides experimental data on the effective use of a new lubricating composition, which includes industrial oil any brand with addition nanometal component friction pair, has lower hardness. It is shown that this composition significantly reduces wear resistance rails and wheels rolling stock during operation, prevents electrochemical corrosion pair wheel–rail and, most importantly, stabilizes coefficient at optimum level after relatively short operating time. The experiments were performed “sample bandage material railway wheel—a sample rail material”, ratio hardness (Rockwell hardness, HRC scale—35.3) to 1.1. Test results show in case lubricant, BioRail brand, nanomaterial metal sample, three hours operation was practically not observed. Moreover, average value for maintained 0.25, optimal wheel–rail. Similar using only same lubricant showed much worse results.
