Atomistic mechanism of activation controlled liquid metal corrosion at the Fe-Pb interface
A bcc iron bicrystal in contact with liquid lead is studied in molecular dynamics simulations to describe the atomistic mechanism of liquid metal corrosion in the activation controlled case. In this process, the main structural features involved are Fe grain boundaries and Fe-Pb interfaces. The atomistic model considered reveals that the interplay of atomic processes such as surface self-diffusion of Fe and dissolution of Fe into Pb determines the mechanism and kinetics law of liquid metal corrosion. Analysis of the proposed mechanism explains the dependence between the kinetics of liquid metal corrosion and the grain size of the specimen.
