Corrosion mechanism of laser-melted AA 2014 and AA 2024 alloys

The corrosion performance of laser-melted AA 2014-T6 and AA 2024-T351 alloys, using a 2 kW CW CO2 laser, has been examined to gain insight into the factors influencing pitting corrosion resistance. Examination of laser-melted surfaces in terms of microstructure and phase analysis was performed using scanning electron microscopy (SEM), with associated elemental analysis by energy dispersive X-ray (EDX) spectroscopy, electron probe microanalysis...
