| Summary: | In this work organo-metallic complexes of 8-hydroxyquinoline of copper, manganese and zinc were used as lubricant additives. The tribological tests were performed using four-ball machine. Test balls were chrome alloy bearing steel, with diameter 12.7 mm (0.5 in.). Dependence of friction coefficient and wear scar diameter on applied load was tested. Due to the obtained results one can conclude that addition of metal 8-hydroxyquinolinate improves anti-wear properties of the lubricant, because the wear scar diameter is significantly smaller for the composition containing organo-metallic complex than for lithium grease. Moreover, the results revealed that for high loads the wear scar diameter was smallest for the composition with the copper additive. |
