Özet

In this study, the tribological performance of nano-silver particles prepared at different concentrations was investigated by the parameters of temperature, friction coefficient, weight loss and surface roughness. Moreover, the effects of the aggregation behaviour of nanoparticles were analysed. According to the results, when the nano-silver concentration increased from 4% to 12%, weight loss decreased by 33.99%, surface quality increased by 21.13%, friction coefficient decreased by 18.16% and wear zone temperature decreased by 74.31%. Increased aggregation behaviour adversely affected the wear resistance. Additionally, it was determined that the ethylene glycol has a significant effect on the penetration ability of the nanoparticles.
