Abstract

The present research work has focused to study the influence of base oil mixed with multi-wall carbon nanotubes (MWCNTs) nodular cast iron contacts with the steel to examine the tribological performance. The wear studies were carried out using a pin-on-disc tribometer. In this study, the percentage of oil concentration, the applied load carrying capacity, and the stability of lubrication film were investigated by varying two sets of sliding conditions. It was observed that the tribological behavior (friction, lubrication, and wear) was improved when the base oil mixed withMWCNTswhen compared to the base oil alone. Further, the incorporatedMWCNTswith the base oil was enhanced the load carrying capacity and the lubricating oil stability. The mechanisms behind the improvements of lubricating oil withMWCNTson the nodular cast iron were also studied, investigated, and reported.
