The corrosion testing of precision sand and V-process cast magnesium specimens was carried out in a typical three-electrode electrochemical cell, where the working electrodes were made with each of the alloy samples. The reference electrode was the saturated calomel electrode (SCE). The counter electrode was a graphite rod, and the electrolyte was a 0.85 M NaCl aqueous solution (pH 7). Two electrochemical methods were used: potentiodynamic scan and Tafel plots. The working electrode potential was controlled with a potentiostat-galvanostat PAR EG&G 273 coupled to a PC running the SoftCorr II software, which allows the experimental control and data acquisition. The measurements demonstrated that the sand cast magnesium specimen is more susceptible to corrosion, in this medium, compared with the V-process cast sample. Copyright © 2004 by ASME.
