Magnesium is a metal which is more abundant and has very low density but it has a low hardness and it has less wear resistance. To improve the properties of magnesium, SiC ceramic particles are reinforced. Composite is fabricated by powder metallurgy technique by varying the content of Mg in the range of 99.5%, 99%, 98.5 and 98% and SiC in the range of 0.5%, 1%, 1.5% and 2% by weight respectively. Mechanical alloying was done prior to the fabrication of composites by using ball milling with the milling parameters like ball to powder ratio, milling speed, milling duration and process control agent are 20:1, 250rpm, 10hrs, and methanol respectively. The mechanically alloyed powders were compressed in a die with the sample size of 8mm diameter with 35mm length at a pressure of 500MPa by using the 50-tonnes/ square inch hydraulic press. The compacted samples were sintered in the furnace at 550°C and maintained for 2hrs in the argon atmosphere and then furnace cooling was done to improve the sintering property. The fabricated magnesium composite samples are subjected to hardness and wear test evaluation. The wear test results indicate that the obtained higher hardness samples of 98%Mg-2%SiC composite pin shows better wear resistance and friction force responses when compared to other samples at all the parametric conditions of load and velocity. Then the wear mechanisms that has occurred on the worn out pin surface was examined by using scanning electron microscope. © 2019 Elsevier Ltd. All rights reserved.
