This work investigates the acoustic, electrochemical, and microstructural characteristics of aluminum alloy 6061 (AA6061) modified with zinc and tin to enhance sound attenuation. The effects of modifying the commercial aluminum alloy 6061 with the incorporation of Zn and Sn were analyzed for their impact on acoustic properties, electrochemical behavior, and microstructural changes. Zn and Sn incorporation alters the acoustic and electrochemical performance of AA6061. Tin was observed at the grain boundaries and zinc oxides were found in the aluminum grains. Young's modulus was determined using the impulse excitation technique. Zn and Sn block the formation of the aluminum oxide passive layer. Adding Zn and Sn into the AA6061 caused a slightly less negative cathodic potential with Zn than Sn. |
