Abstract:– This article reports on the relationship between the arcing current and the microstructural and corrosion behaviour of discrete weld droplet deposited on sugar mill roller shells made from grey cast iron during hardfacing in a typical sugarcane factory. Hardfaced droplet deposits were removed from three simulated roller shells, which were arced with different current, and subjected to porosity, microhardness and corrosion tests. The results revealed that the percentage porosity, microhardness value and corrosion rate significantly depended on the welding current; the rate of corrosion generally increased with a decrease in porosity and an increase in microhardness. | ||
