Abstract: Nickel Aluminum Bronze (NAB) alloys display characteristics like superior strength and excellent wear resistance. In this work, NAB was reinforced using various volume fractions of yttrium (Y2O3) and/or carbon nanotube (CNT) particles prepared using the Powder Metallurgy (PM) method. General full factorial design was used in MiniTab19 software. The experimental results showed a significant influence of the Y2O3 and CNT particles on mechanical and physical properties. The optimal results were recorded for the sample having 6 vol.% of Y2O3 and 1.5 vol.% of CNT. This sample exhibited the highest effect on characteristics with hardness value of 288 Hv, porosity of 10.2%, surface roughness of 0.15 µm, average particle size of 37.55 µm, wear rate of 0.0000313 g/mm, and friction coefficient of 0.68. The results demonstrated that there is an improvement of 64% in microhardness in comparison with the base alloy. Porosity, surface roughness, wear rate, friction coefficient, and average grain size were reduced by 4%, 81%, 71%, 31%, and 24%, respectively.
