| Abstract Scope |
A major limitation of magnesium-based materials is their poor surface properties, such as, wear, and corrosion resistance. A major challenge in potential magnesium-based components is to control their wear and friction characteristics to avoid their premature failure during service. In this presentation, Mg-5Nb metal–metal composite reinforced with varying volume fractions of nano silicon carbide (SiCn) ceramic particles (made by the technique of disintegrated melt deposition) will be presented and discussed. The improved wear resistance shown by the nanocomposites can be attributed to the conjoint and mutually interactive influences of grain refinement, presence of hard, brittle and elastically deforming SiCn particles, formation and presence of hard and brittle intermetallic phase, and formation of an oxide layer. These synergism contribute to increasing the hardness of the nanocomposites with a concomitant improvement in wear resistance. The intensity of wear mechanisms in the composites will be compared with the nanocomposites. |
