Microstructure and Corrosion Behaviour of ZA-27/ B4C Particulate Composite

Authors: Saliu AM, Onimisi Z, Ubandoma PZ


The corrosion behaviour of ZA27/B4C particulate composites in an aerated sodium chloride solution was studied. ZA-27/B4C particulate composite at different weight percentage (2.5%, 5%, 7.5%, 10%) of B4C particles were produced using the stir casting method. The corrosion behaviours of both unreinforced alloy and reinforced composites were examined using potentiodynamic test in a salt solution (3.5 wt.% NaCl). Optical microscopy was used to examine the microstructure of the composites produced. The results showed improved corrosion resistance for metal matrix composites compared to corrosion resistance of the matrix in 3.5 wt.% NaCl solution. Increasing the weight percentage of the reinforcement particulates decreased the corrosion rate of the composites.
