The current study aims to investigate the tribological behavior of Ni3Al-CNT composites doped with boron and to study their wear behavior under varying loads. Ni3Al-CNT composites with CNT contents of up to 5 wt% were processed using EARS (Electrically Activated Reaction Synthesis) followed by subsequent high-temperature annealing. Annealing resulted in an increase in microstructural homogeneity and microhardness of the composites. An increase in CNT content resulted in a reduction in the wear rate and the coefficient of friction of the Ni3Al-CNT composites, due to the lubricating effects of CNTs. The wear behavior was also studied under varying loads, and the improvement of wear properties with increase in CNT content was observed under all the applied loads, although the average wear rate increased with increase in the load. Due to the higher loads and higher debris formation, three-body abrasive wear played a primary role in the wear behavior of the composites along with adhesive and oxidative wear. Frictional Force/ Coefficient of Friction also showed a similar trend of average frictional force increasing with the increase in load although decreasing with the increase in CNT content for the same load. The present study has significant implications for Ni3Al-CNT composites in articulating applications.
