Abstract [en]

For the booming automobile industry, the demand for the light weight and more efficient materials are increasing day by day. Grey cast irons have been playing a crucial role in the manufacturing of the disc brake rotors. But the material of grey cast have many drawbacks such as the weight, and corrosion factors, which will have a great influence on meeting the market demands and also from the environmental point of view. Aluminium plays a vital role in meeting these demands for the growing industry, but the metal aluminium has its own limitations and then arise the demand for the alloying elements. The alloying elements considered in the current thesis work are the Al-20%SiC and the Al-Hypereutectic alloy. The Al-20%SiC alloy is currently used by the manufacturer for the production of their lightweight disc brakes and it is currently manufactured with the process of squeeze casting. The metal exhibits better mechanical properties and other factors that the manufacturer look into. But as the industry is growing in a rapid phase and there is an increasing demand for more reliable alloying elements. The manufacturer considers about the usage of Al-hypereutectic alloy to replace the usage of Al-20%SiC alloy. The current thesis work is focused on the study of the mechanical properties and tribological behaviour of both of these alloys and to verify, if the new alloy can meet the demands of the manufacturer.
