It is applied to the various high-technology fields such as space flight, aviation, environmental protection, the energy and biological medicine.
At present, the method preparing foam metal has casting, foaming, sintering process and sedimentation.Wherein, first three technique
The shortcomings such as the foam metal of preparation, has distribution of pores and size is uneven, and mechanical property is prominent and discreteness is big；Sedimentation
In electrochemical process, owing to substrate is confined to conductive material, and limited by limiting current density, therefore deposition velocity is relatively
Slowly, production efficiency is low, relatively costly.But, chemical plating process is possible not only on the metallic substrate (ferrum, rustless steel, aluminum, copper etc.)
Can also on nonmetallic substrate (pottery, glass, diamond, carbon plate, plastics, resin etc.) deposition metal level (as nickel, ferrum, copper,
Gold, lead etc.).Without additional power source, there is not the impact that electric force lines distribution is uneven, the coating of deposition is uniform, fine and close, hole
Less, hardness is high, have fabulous process based prediction model.
Roughening treatment during control, chemical plating process and substrate are removed technology and combine by the present invention, it is thus achieved that internal diameter is controlled
Metal hollow ball monomer.Then being mixed with corresponding metal nanoparticle by single body hollow ball, cold-rolled sintered shaping obtains foam
Metal blocks.First, by controlling different coarsening times, different-grain diameter graininess substrate is obtained (such as silica-gel desiccant, dioxy
SiClx, silicon)；Secondly, chemical plating is utilized to prepare metal level on non-metallic particle substrate；Strong base solution is finally utilized to remove lining
The end, it is thus achieved that the metal ball of hollow structure.Substrate size (i.e. metal ball internal diameter) is determined by coarsening time, and shell thickness is by chemical plating
Sedimentation time determine.So, this technique has the advantages such as simple, convenient, economic and spherical shell internal diameter is controlled, particularly suitable
In the foam metal material preparing different inner diameters.
Summary of the invention
It is an object of the invention to provide a kind of technology and cold-rolled sintered of roughening treatment during control, chemical plating, substrate being removed
Combine, it is thus achieved that the technique of foam metal block.And make it be applied to various high-technology field.
