Abstract
Two‐dimensional computer simulations have been used to demonstrate the main atomistic features of a percolation model for alloy passivity. The simulations reproduce all the qualitative features of passivation in Fe‐Cr alloys, including a critical alloy composition and a passivation potential which decreases with increasing Cr content. New features which would appear in three dimensions are discussed.Keywords
