Corrosion of additively manufactured (AM) alloys has recently been gaining interest in the materials community. There is, however, a lack of consistency regarding results and methods among studies making it difficult to compare data and draw broad conclusions. In this study, we will survey the electrochemical behavior of AM Al-10Si-Mg in a range of standard solutions in order to assess variability in different electrolytes. Polarization and electrochemical impedance spectroscopy testing in a range of NaCl and standard solutions, such as B117 (5% NaCl), G85-A2 (5% NaCl plus acetic acid), and G110 (5% NaCl plus 0.3% H2O2) will reveal the effect of electrolyte on the oxide properties and corrosion rate. These results will aid in our understanding of existing and future data by facilitating comparison across research groups who may utilize varying experimental methods and electrolytes.
