Tribological Behavior of Inconel 718 Nickel-Based Super Alloy Doped with Graphene Nanoplatelets

In continuation of our previously published work entitled Mechanical and Corrosion Behavior of Inconel 718 Nickel-Based Super Alloy Doped with Graphene Nanoplatelets , the present study investigated the tribological performance of modified IN 718 doped with GrNs. Friction and wear properties were analised using an advance universal tribometer, while surface mophologies were studied by SEM. The modified SA tribological properties validation was done in relative comparison to those of pure IN 718 . Mechanical properties with higher  , younger modulus values, better morphologies, higher AWI, lower SWR and µ values were noted on the modified IN 718. Nonetheless, an increase in the load proved to affect the tribological oxide layer properties of both pure and modified IN 718. room temperature. The tests were run under dry lubrication conditions that are explained further ahead. A steel ball was used as the counterpart material against both standard and modified materials. The diameter size of the steel ball was 1.50 mm, and the acquisition rate was 3.14 Hz, with an equivalent stroke length of 6 mm. The measurements were intended to incorporate friction and wear properties from both pure and modified IN 718.
