Abstract Scope |
Nanoporous metal foams possess interesting properties including good electrical and thermal conductivity, surface-to-volume ratio and yield strength. Individual properties can be tuned through changes in the foam morphology, including ligament and pore size. Gradient nanoporous metal foams in particular allow for novel combinations of chemical and mechanical properties.
As a first step in the design of gradient nanoporous foams, the composition and the role of the interfaces must be understood. Thus, bilayer nanoporous copper foams are synthesized by dealloying Cu-Al/Cu-Al or Cu-Al/Cu-Zn sputtered films via free corrosion, with the goal of producing a sharp gradient in ligament size between layers. Cross-sectional SEM is performed to characterize the as-sputtered film microstructure, the representative foam morphology, and the evolution of the dealloying reaction front as a function of time. |
