Resumen o descripción

Light aluminum alloys have a great importance in industry owing to generally accessiblecosts, low density, good machinability, and corrosion resistance under certain environments.The present work studies aging treatments that preform important roles on the distribution andmicrostructural changes of two AlMg-Zn alloys, and the resulting e_ect on the corrosion behavior.The experimental AlMg-Zn alloys were cast and then heat treated at 200 _C, after the solubilizationtreatments were made, using di_erent treatment times. These alloys showed important changes intheir corrosion mechanisms, but mainly, corrosion started at AlxMgyZnz complex phases in bothalloys. The optimal corrosion rates were reached after 5 and 24 h of heat treatment. These resultswere obtained through electrochemical techniques in NaCl solutions, and by metallographic analysisusing SEM and optical microscopy.
