Surface characterisation of brass alloy in the correlation of hardness and electrical resistivity by carbon ion implantation

Abstract

Material modification, as per demand of era, has been explored by several groups in different areas focusing its engineering prospect for better performance. Carbon ion implantation, using four different doses, has been done on α-brass (64% Cu; 36% Zn) to see its effects on hardness, microstructure and electrical resistivity. Carbon ions distorted the crystalline surface, increased defect density and hardened the surface by 13.2%. The crystallite size was found decreased by 41.15%, which in turn caused a significant increase in electrical resistivity, i.e. 234.8%. Overall, the lattice parameter found increased from 3.680 to 3.688 Å. SEM morphology exhibited nonuniform agglomerations in the form of pits, cracks, voids, cavities, craters, particulates, droplets and petals like structures at the surface by carbon ion implantation.

Electrochemical and physiochemical studies on the effects of thiadiazole derivatives in corrosion inhibition of Muntz metal in sulfide-polluted marine environment

“…The minimization of corrosion of copper and its alloys in water transport systems, by alloying and incorporating inhibitors, has been extensively studied [11,12]. Protecting metals and alloys against attacks in many industrial environments requires the addition of inhibitors [13,14]. Corrosion is a severe issue for the service life of alloys used in industry.…”
