摘要

In this work, we present the decreased susceptibility to intergranular corrosion in AZ31 magnesiumalloys welded by friction agitation process, varying the rotation and advance speed. To induce thecorrosion effect was used as electrolyte a solution of 30g of NaCl and 10 ml of concentrated HCl,monitoring of degradation analysis was performed using electrochemical impedance spectroscopy andpotentiodynamic polarization curves Tafel. Moreover, microstructural analyzes were performed of thegrain boundaries by means of metallographic microscope and scanning electron microscope. It wasfound that a higher relationship among forward speed / rotation speed produces a weld bead withimproved resistance to intergranular corrosion, possibly associated to a larger grain size in the stirredzone, in turn related to increased heat input by friction process.
