Friction Properties of Carbon Nano Onions as Lubricating Oil Additives
摘要
Abstract
Carbon nano onions (CNOs) were prepared by chemical vapor deposition (CVD).The outer layer was graphite layer, which contained Fe-Ni catalyst particles, and the shape was similar to spherical and played the role of "micro-bearing" in mechanical lubrication.The friction performance of the lubricant additive was investigated by rotating oxygen bomb method, four-ball friction tester and lubricating oil anti-wear tester.The results show that carbon nano onions have good anti-wear performance.When the mass fraction of CNOs is 0.05%, the abrasion resistance of lubricating oil is improved obviously.At this time, the extreme pressure value is increased by 64%, the diameter of grinding spot is reduced by 78%, and the oxidation stability is better.关键词
