Abstract: The production of a porous copper-zinc structure includes providing copper ink, creating a 3D model of the porous copper-zinc structure, 3D printing the copper ink into a porous copper lattice structure using the 3D model, heat treatment of the porous copper lattice structure producing a heat treated porous copper lattice structure, surface modification of the heat treated porous copper lattice structure by nanowires growth on the heat treated porous copper lattice structure producing a heat treated porous copper lattice structure with nanowires, and electrodeposition of zinc onto the heat treated porous copper lattice structure with nanowires to produce the porous copper-zinc structure.

Abstract: Use of a montmorillonite as a corrosion inhibitor for a metallic substrate. A corrosion inhibiting composition for a metallic substrate and a method of reducing corrosion on a metallic substrate. The montmorillonite preferably having a unit cell composition of [(Si8)IV.(Al3.33Mg0.67)IV.O20(OH)4]0.67M+ in which the superscripts (IV) and (VI) denote respective tetrahedral and octahedral layer cations and M+ denotes a univalent or equivalent compensating cationic charge.
