Owning to their markedly improved mechanical properties, aluminum metal matrix composites (AMMC's) have found a global approval as a reliable material for different applications. Nonetheless, researches on several reinforcements have proved that AMMC's properties also extend to show an improvement in electrochemical performance for being used as aluminum sacrificial anodes. Stir casting process is considered the most cost-efficient route for production of MMC's on industrial scale, the process itself is simple but requires fine tuning of the different processing parameters to obtain homogenous and high-quality cast products. In this research, stir casting process has been implemented and optimized for producing metal matrix composite of alloy Al-5%Zn-0.1%Sn incorporated with commercially available manganese dioxide concentrate for sake of manufacturing high performance aluminum sacrificial anodes under different solution treatment cycles. The electrochemical behavior of produced AMMC will be evaluated in separate publication as second part of the present work. © 2020 Korean Academy of Asthma, Allergy and Clinical Immunology.
