WebIn this paper we present a new framework, based upon percolation theory, within which various aspects of corrosion in alloy systems may be understood. We have developed a new model of selective dissolution (de-alloying) which is able to account for all the known features of the phenomenon. WebJul 12, 2024 · The selectivity of alloy dissolution decreases as the current density increases. (3) The galvanostatic dealloying of the Zn 0.67 Ag 0.33 alloy leads to formation of characteristic uniform porous structures with pores and ligaments of approximately the same size lying in the interval of 0.5–5 µm.
