Corrosion and wear resistance of hypoeutectic Zn-Al alloys as a function of structural features

► A combined study encompassing the grain and dendritic scale was here performed. ► The results include corrosion as well as wear parameters. ► Even at the highest Al wt%, the corrosion resistance depends on the structure. ► The wear resistance increases from the columnar to the equiaxed structure. ► A clear inverse relation is observed between the wear resistance and λ2.
