Abstract

In this investigation, Zn-Al alloy metal-matrix nano composites thatreinforced via various weight percentages (2%, 4%, 6%, and 8%) ofnanosilica (SiO2) particles were fabricated applying the technique of stircasting. Behaviors of the corrosion of the unreinforced alloy andreinforced composites were measured utilizing a potentiostat test in a (3.5wt.% NaCl) salt solution. The optical microscopy was employed toinvestigate the surface microstructure of the composite. Microstructureanalysis manifested that the uniform distributions of the reinforcingparticles in the composites are alike, consisting of a dendritic structure ofthe zinc alloy matrix with an excellent reinforcing particles steadydispersion. The improved results of the corrosion resistance for the metalmatrix composites showed an excellent resistance to corrosion than thematrix in the (3.5 wt.% NaCl) solution. Raising the weight percentage ofthe reinforcement particulates of nansilica (SiO2) reduced the compositesrate of corrosion
