Abstract

Alloy corrosion is a field of scientific study that combines electrochemical kinetics with aspects of the morphological evolution of surfaces. The basic alloy corrosion process is de-alloying, where a significant difference in the equilibrium metal/metal-ion electrode potentials for two metals occurs. In alloy systems where the ambient temperature corresponds to a small fraction of the homologous melting temperature, site-percolation thresholds set a lower bound on the parting limit. The parting limit represents the critical content of reactive alloy components that is required to allow de-alloying at an arbitrarily high anodic potential. Another field of alloy corrosion is passivation, where sharp compositional threshold behavior is observed.
