EFFECT OF HEAT TREATMENT ON THE CORROSION BEHAVIOR OF Al-10%WT Mg ALLOYS

EFFECT OF HEAT TREATMENT ON THE CORROSION BEHAVIOR OF Al-10%WT Mg ALLOYS

In the present investigation, the effect of heat treatment on the electrochemical behavior of Al-10% wt Mg alloy in 3.5% wt NaCl is studied by different electrochemical techniques such as polarization technique (Tafel plot) and electrochemical impedance spectroscopy. It has been shown that the corr...

It has been shown that the corrosion resistant of the alloy decreased with the ageing treatment at 250 °C for 24 h. However, this latter increased with naturally ageing. The SEM (electron microscope) and Energy Dispersive EDS characterization have shown that the alloy with the two treatments of ageing became susceptible to the pitting corrosion. https://journals.scicell.org/index.php/AMS/article/view/224Al-Mg alloyageing treatmentcorrosionmicrostructure
