  • In this study, we investigated the effect of the addition of Sr (0wt%, 0.1wt%, 0.2wt%, and 0.3wt%) on the microstructure and corrosion behavior of Al3Ti/ADC12 composite by optical microscopy, X-ray diffraction, scanning electron microscopy, and energy diffraction spectroscopy. The results reveal that the α-Al phases were nearly spherical and 40 μm in size and that the eutectic Si phases became round in the composite when the Sr content reached 0.2wt%. The Al3Ti particles were distributed uniformly at the grain boundary. The results of the corrosion examination reveal that the Al3Ti/ADC12 composite exhibited a minimum corrosion rate of 0.081 g·m–2·h–1 for an Sr content of 0.2wt%, which is two thirds of that of unmodified composite (0.134 g·m–2·h–1). This improved corrosion resistance was due to galvanic corrosion, which resulted from the low area ratio of the cathode to anode regions. This caused a low-density corrosion current in the composite, thereby yielding optimum corrosion resistance.

      Abstract
    • In this study, we investigated the effect of the addition of Sr (0wt%, 0.1wt%, 0.2wt%, and 0.3wt%) on the microstructure and corrosion behavior of Al3Ti/ADC12 composite by optical microscopy, X-ray diffraction, scanning electron microscopy, and energy diffraction spectroscopy. The results reveal that the α-Al phases were nearly spherical and 40 μm in size and that the eutectic Si phases became round in the composite when the Sr content reached 0.2wt%. The Al3Ti particles were distributed uniformly at the grain boundary. The results of the corrosion examination reveal that the Al3Ti/ADC12 composite exhibited a minimum corrosion rate of 0.081 g·m–2·h–1 for an Sr content of 0.2wt%, which is two thirds of that of unmodified composite (0.134 g·m–2·h–1). This improved corrosion resistance was due to galvanic corrosion, which resulted from the low area ratio of the cathode to anode regions. This caused a low-density corrosion current in the composite, thereby yielding optimum corrosion resistance.
