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