Description:
This paper presents effect of using different materials on surface properties and erosion resistance of turbine blades, three basic material copper, aluminum and steel where used in this work. Steel exposed to three surface treatment hardening, flame hardening and carburizing processes to improvement their surface properties. Wear rate, hardness and impact resistance were measured for each group. the results showed that using of copper or aluminum is not recommended, steel showed good surface properties, best result obtained after thermal surface treatment, carburizing give higher wear resistance, greater surface hardness compared to hardening and flame hardening process respectively, while flame hardening provided the specimens with greater toughness as compared to carburizing and hardening process respectively. Microstructural investigation was achieved using SEM and EDS technique.
