ABSTRACT
The features of selective anodic dissolution of Al11Au6 intermetallide and Au–Cu–Ag solid solution in the melt of CsCl–KCl–NaCl eutectic at 520оС were studied. Microporous structures containing up to 95 mol % of gold were fabricated in the potentiostatic regime. It is shown that the pore size and distribution depend essentially on the nature of the alloy, and the mechanical strength of the sample during and after the dealloing is strongly influenced by the magnitude of the applied potential.
