The Effect of Aluminum Clad on the Electrochemical Properties of the Similar Weld of Friction-Stir Welding of 2524

Abstract:

Microstructures, static weight loss and potentiodynamic polarization curves were carried out on the Friction-stir welds of Al clad 2524 alloy with the thickness of 1.35 mm. The results indicated that the microstructures of the Nugget had been remarkably reshaped. A dynamical recrystallization took place on the zone of the weld nugget and an equiaxed grain structure formed. The static weight loss and potentiodynamic polarization curves results indicated that the resistance of corrosion of the base material (with aluminum clad) was superior to that of its weld, but the anti-corrosive ability of the weld was superior to that of the base material without aluminum clad.
