Abstract

TRIBOLOGICAL INVESTIGATION ON MICRO TITANIUM AND B4C REINFORCED AL-Mg ALLOY USED IN AUTOMOTIVE APPLICATIONS.

ABSTRACT

Today’s interest in Aluminium-Magnesium alloys for automotive applications is based on the combination of high strength properties and low density.[1] For this reason Aluminium-Magnesium alloys are very attractive as structural materials in all applications where weight savings are of great concern. In automotive applications weight reduction will improve the performance of a vehicle by reducing the rolling resistance and energy of acceleration, thus reducing the fuel consumption and moreover a reduction of the greenhouse gas CO2 can be achieved. The use of pure Aluminium-Magnesium is rare due to its volatility at high temperatures and it is extremely corrosive in wet environments. Therefore the use of Aluminium-Magnesium alloys when designing aerospace and automotive parts is critical. Specific alloys are better for certain applications and often also need a coating to provide the longest life of the part[2 -3] Hence in our present study we have developed a new hybrid composite by mixing of Aluminium-Magnesium alloy, Micro Titanium and Boron Carbide powders using a Stir- Casting technique at different weight fractions, i.e. addition of Boron Carbide (1%, 2%, 3%) and Micro Titanium (5%). After production, the machining of the hybrid metal matrix composites is carried out as per ASTM standards. This review paper is aimed to summarize tribological properties and to study the effect of reinforcements on Aluminium-Magnesium alloy. This has resulted in the improvement in the properties of hybrid composites.
