Tittle:
New method for high-performance metal foams by an electrodeposition process
Summary:
An Italian university research team has developed a new method for the preparation of high-performance metal foams with coating of metal matrix and graphene by an electrodeposition process. The high-performance metal foams have several applications in sectors such as automotive, aerospace, fuel cells.
The technology is covered by patent. The partners sought are SMEs, large companies and research centers for license agreement.
Description:
The technology is proposed by an Italian university research team involved in mechanical engineering field.
Metal foams are porous materials with open-cell structures having an external surface that can essentially consist in one or more metal coatings deposited, e.g. by electrodeposition.
This technology refers to a new method for the preparation of high-performance metal foams with a coating of metal and graphene capable of giving to metal foams better mechanical properties such as compression strength, energy absorption capacity, flexibility and traction strength.
The technology is based on the observation that by varying the amount of graphene used in the preparation method, possibly in combination with other parameters of the method such as metal foam porosity, coating thickness and metal, it is possible to modulate the mechanical properties of open-cell metal foams, remarkably improving them.
In fact, coated metal foams with a thermal conductivity improved by up to 150% and a yield strength improved by up to 50%, compared to non-coated metal foams, were obtained.
The enhancement of thermal conductivity increases with the quantity of covering, and in particular with the amount of graphene.

The partners sought are SMEs, large companies and research centers active in sectors such as automotive, aerospace and fuel cells. The technology proposed is covered by patent. Since the high-performance metal foams have several applications, the license agreement allows one or more applications according to the agreement between the involved parties.
Advantages and Innovations:
The proposed method is covered by patent.
The technology allows the preparation of high-performance metal foams with better mechanical properties such as compression strength, energy absorption capacity, flexibility.
The preparation of open-cell metal foams with a coating of metal and graphene comprises two steps of electrodeposition:
- electrodeposition of a first layer of metal or an alloy thereof and graphene on metal foam;
- electrodeposition of a second layer of metal or an alloy thereof on the metal foam.
The metal foams will preferably be selected from metal foams of aluminum, copper, nickel, iron, titanium, magnesium, lead and the alloys based on such metals.
The thickness of the layer of metal and graphite will preferably be at most 100 microns.

The high-performance metal foams have several applications in sectors such as automotive, aerospace, fuel cells, power electronic systems, etc. for the heat exchange and for the corrosion resistance.
