Abstract
A novel approach is proposed and developed to fabricate nanoporous structure on metal substrate for potential functionalization by laser deposition of Cu- Mn alloy hybrid selective electrochemical dealloying. With a deep understanding of the dealloying behavior, we are able to selectively dissolve the relative inert element Cu instead of conventionally the relative active element Mn. As a result, a novel nanoporous Mn structure was successfully realized by our hybrid approach. Due to the characteristics of laser deposition, we are also able to form this nanoporous structure on any location with any shape. This paper reports in detail the fabrication approach for the nanoporous structure, including the formation basis, the influence of dealloying time, current density and laser scanning speed on the nanoporous structures. The characterization of this nanoporous structure is also well presented covering the microstructure and homogeneity.
