Abstract
This manuscript deals with the electro-deposition of Cu on aluminum foams. Metallic foams are highly porous materials which present complex structure of three-dimensional open cells. This aspect causes strong limitations in mass transport due to electro-deposition technology. Experimental tests were performed to study the influence of the operational parameters on the overall performance of the coated aluminum foams. The experimental findings revealed that the manufactured metal foams were characterized by a high thermal conductivity and low process costs, making these materials very promising in many technological fields. On the basis of the experimental results, analytical models are proposed to predict the quantity and the quality characteristics of the coating.

Summary
Aluminum foams are a recent class of materials for their characteristics have been stimulating great interest in many technological domains. Metal foams possess a light weight and can absorb high impact energies, and they are very efficient vibration damping and are very suitable for thermal exchange applications These properties make them suitable for a wide range of industrial applications [1]. In addition to the lack of knowledge, the production of foams, by using other metals that are not aluminum, is still characterized by industrially unacceptable costs [1] In this context, this paper intends to propose an alternative process to the bulk ones in which copper foams are obtained by electro-deposition. Open cell metal foams have a very complex structure This aspect causes strong limitations in mass transport due to electro-deposition technology [5]. The experimental findings revealed that the manufactured metal foams were characterized by a high thermal conductivity and low process costs, making these materials very promising in many technological fields
