Abstract—Selective dissolution, alloying, and change in the crystalline structure independently determine the
potential of zero charge, charge density, and specific free interphase energy of the interface between the Ag–Au
alloys and an aqueous solution of potassium fluoride. This is to a considerable extent associated with the close-
ness of the metallic system to an ideal state.
