Abstract

Novel LM24 hybrid composite materials varying in the percentage of SiC particulate reinforcement were fabricated by stir casting technique (liquid metallurgy route) and optimized at different parameters like applied load, sliding speed, sliding distance by taguchi method. The specimens were examined by Rockwell hardness test machine, Pin on Disc, Scanning Electron Microscope (SEM) and Optical Microscope. A plan of experiment generated through Taguchi’s technique is used to conduct experiments based on L9 orthogonal array. The developed ANOVA and the regression equations were used to find the optimum wear as well as co-efficient of friction under the influence of applied load, sliding speed, sliding distance. The dry sliding wear resistance was analyzed on the basis of “smaller the best”. Finally, confirmation tests were carried out to verify the experimental results.
