The effect of addition of hardystonite on the strength, ductility and corrosion resistance of WE43 magnesium alloy

A composite material based on the WE43 magnesium alloy and containing nano-sized hardystonite ceramic particles was processed by means of friction stir processing (FSP). Compressive strength strain-at-failure increased as a combined result FSP nanoparticle reinforcement. The results potentiondynamic polarization electrochemical impedance spectroscopy tests indicated that corrosion mechanism nanocomposite is combination uniform localized pitting which not different from base metal. However, rate significantly decreased reduced metal after effect to reduce corrosion. resistance 192.48 339.61 1318.12 ?/cm2 applying addition particles, respectively. Indeed, fabricated shows resistance. Enhanced strength, ductility were attributed grain refinement in fragmentation redistribution second-phase matrix, occurring during FSP.
