  • Corrosion Behavior of Zinc Alloy Based Metal Matrix Composites Reinforced with nano BN
  • Abstract.In this study, zinc alloy metal matrix nanocomposites reinforced by different weight
    percentage (2%, 4%, 6%, 8%) of nano BN particles were produced using the stir casting
    technique.
    The corrosion behaviors of both unreinforced alloy and reinforced composites were examined
    using potentiostat test in a salt solution (3.5 wt.% NaCl). Optical microscopy was used to examine
    the microstructure of the composites surface have been found to be stable with the distribution of
    uniformed reinforce particles and strong interfacial bonding between the matrix alloy and
    reinforcement. The results improve corrosion resistance for metal matrix composites exhibited
    better corrosion resistance than the matrix in 3.5 wt. % NaCl solution. Increasing the weight
    percentage of the reinforcement nano BN particulates decreased the corrosion rate of the
    composites.
