Paper Title:
Effect of Bi Content on Electrochemical Properties of Al-Bi-Sn-In-Ga Alloys
  Abstract

Five Al-Bi-Sn-In-Ga alloys with different Bi content were designed and prepared. Their electrochemical properties in 3% sodium chloride solution, the distribution of alloying elements and surface morphologies were studied by means of loss of weight method, polarization curve, electrochemical impedance spectroscopy (EIS) and energy spectrum analysis. The results indicate that, a good deal Bi and other alloying elements form new phases which exist in grain boundaries in the form of dot or granule, and Bi rich regions are prone to become the inductive points of pitting corrosion. Moreover, there is a certain linear relation between Bi content and the self corrosion rate.
