Abstract
The effect of molybdenum on the morphological and wear behaviour of Nigeria Foundries grey cast iron (8) [NFgrey(8)] has been studied. The microstructural and mechanical properties of the cast samples for the control and the NFGrey(8)/Molybdenum alloy were characterised using SEM, XRD, Brinell Hardness and impact energy testing Machine respectively. MATLAB linear curve fitting technique was used to obtain the approximate linear equation via first differential approach. The results show that molybdenum addition improved significantly the wear resistance of the NFGrey(8) cast iron. However, the toughness of the alloy was sacrificed. The strong and hard intermetallic compounds within the matrix are attributable to wear resistance of the NFGrey(8)/Mo alloy.
