| Outline of Final Research Achievements |
In this work, to clarify the tribological properties and the power transmitting capacities of lubricating oils with metal nanoparticles (Ag, Cu and Ni nanoparticles) as an additive, a wear test and a gear test were carried out using a four-ball machine and a power-circulating gear machine, respectively.
From the test results in the wear test, the effect of Cu nanoparticles on the wear properties was recognized. Especially, when the additive amount of Cu nanoparticles was 0.2 and 0.6 wt%, the wear scar diameter was reduced by about 26～28% compared with the base oil. In the gear test, the scuffing-load capacities of gears increased due to the Cu nanoparticles additive.
