Wear Behavior of Aluminium Modified Cast Iron in Comparison With Conventional Gray Cast Iron

Abstract

Wear behavior of aluminium modified cast iron with a conventional gray cast iron (known as Fe-C-Si CI) has been investigated through microstructural and wear property characterization. The aluminium modified cast iron (known as Fe-C-Al CI) sample was produced via melting of pig iron, mild steel and ferro-aluminium addition (as a source of Al). The microstructural study was performed using scanning electron microscope (SEM) whereas, wear and friction test was carried out using universal wear testing machine at temperature of 25°C, 100°C, 200°C and 300°C. The Fe-C-Al cast iron showed lesser graphite content compared to Fe-C-Si cast iron. The wear and friction test results showed that Fe-C-Al cast iron has lower wear rate and friction value at higher temperatures compared to those of the Fe-C-Si cast iron.
