Influence of Friction Stir Welding on the Corrosion Resistance of Al6061
摘要
AluminumAluminum-based alloys are utilized in a variety of advanced commercial applications such as automotive, defense, marine, and aerospace. This is ascribed to a collection of outstanding characteristics, such as a high strength-to-weight ratio, and high ductility. AluminumAluminum-based alloys exhibit low corrosion resistanceCorrosion resistance when exposed to saline media. The Friction stir weldingFriction stir welding (FSW) technique was used to produce welded joints of aluminum alloyAluminum alloys 6061 plates. This work studies the effect of friction stir weldingFriction stir welding on the corrosion response of AA6060-T6. The corrosion behavior of both the welded sample and the base metal sample was evaluated after 15 days of exposure to 3.5 wt% NaCl using an electrochemical impedance spectroscopy (EISElectrochemical Impedance Spectroscopy (EIS)) approach. The surfaces of corroded samples were examined using scanning electron microscopy (SEM) to analyze the surface morphology. The welded sample exhibited more resistance to corrosion than the unwelded sample which was supported by the output of SEM investigation.
