Abstract

This study is a follow-up investigation of the influence of the alloying elements Nd and La on the corrosionCorrosionby immersionImmersion of an extruded and heat-treated Mg10Gd. The previous study made clear that the age-hardened condition has the lowest corrosion rateCorrosion Rate but high pitting corrosionPitting corrosion susceptibility. The extruded Mg10Gd(1Nd)1La shows the lowest pitting factors based on severe corrosion. In this study, the corrosionCorrosion morphology and corrosion rates are discussed based on calorimetric data and 3D-analysis by µCT and compared to the results from the immersion tests. Thermal power and enthalpy readings from the isothermal calorimetryCalorimetry offer information on the reaction kinetics. The... (More)

This study is a follow-up investigation of the influence of the alloying elements Nd and La on the corrosionCorrosionby immersionImmersion of an extruded and heat-treated Mg10Gd. The previous study made clear that the age-hardened condition has the lowest corrosion rateCorrosion Rate but high pitting corrosionPitting corrosion susceptibility. The extruded Mg10Gd(1Nd)1La shows the lowest pitting factors based on severe corrosion. In this study, the corrosionCorrosion morphology and corrosion rates are discussed based on calorimetric data and 3D-analysis by µCT and compared to the results from the immersion tests. Thermal power and enthalpy readings from the isothermal calorimetryCalorimetry offer information on the reaction kinetics. The corrosion rateCorrosion Rate values are discussed based on the evaluation method—in general agreement alloying with Nd reduces the corrosion rateCorrosion Rate. The pitting factor is found to be very dependent on the reference average penetration: weight or volume loss, or evaluation by 3D volume or by 2D cross-sections.
