Wear Characterization of Al/B4C/CNT Composites for Different Alloying Composition

Ashwin C. Gowda, D. P. Girish


Wear is a surface phenomenon that occurs predominantly at the surface of the material. It is majorly due to the rubbing action between two surfaces that is attributed to solid state contact. As wear is a material removal phenomena occurring at the outer surfaces, it is indeed very apt to develop materials that have wear resistant characteristics. Henceforth in the current work, it is therefore judicially justified to develop a composite material with different proportions of carbon nanotube (CNT) and boron carbide (B4C) for obtaining wear resistant characteristics. The objective of present work is to develop an experimental plan to find the important factors and the combination of factors influencing the wear phenomenon to optimize the wear characteristics such that the minimum wear rate and COF is achieved. The plan of experiments are developed based on an orthogonal array, the main aim of orthogonal array is to relate the sliding speed, applied load and sliding distance. The parameters henceforth considered are distinct and affect the performance of composite materials. Taguchi Genechi method gives an overview of conceptual approach that takes into account S/N ratio for optimizing the experimental variables and identifying the significant factors.
