Abstract

In this research paper, dry sliding (unlubricated), corrosion and abrasive wear behavior of ZA27/ Graphene/ B4C hybrid nanocomposites were studied. The hybrid nanocomposite samples were fabricated by powder metallurgy technique. Tribological tests were performed by employing a ball-on-disc type in the unlubricated situation and different loads (1, 2, 5 and 10 N). The examination of the worn and corroded surfaces, the powder characterization was performed using scanning electron microscopy (SEM). The findings indicated that the increase in B4C nano-particle content can positively effect on the corrosion and wear behavior of the hybrid nanocomposites. The electrochemical polarization measurements showed that increasing of the nano B4C content causes high corrosion resistance in the hybrid nanocomposites. The corrosion tests showed that the corrosion rate value of the ZA27/Graphene/B4C hybrid nanocomposites decreased from 59.02 mpy to 16.77 mpy with increasing the nano B4C content from 0.25% to 2%.
