Category）It is made up of the hole of rigid backbone and inside, the Novel engineering with excellent physical characteristic and good mechanical performance
Material, develops rapidly in the later stage eighties 20th century.The superior physical properties that it possesses（As density is small, rigidity is big, ratio
Surface area is big, energy-obsorbing and damping performance is good, sound-deadening and noise-reducing effect is good, capability of electromagnetic shielding is high etc.）Expand to its application field
The fields such as aviation, electronics, medical material and biochemistry.And the metal polyporous material with through hole also has heat exchange heat radiation energy
Power is strong, good penetrability, thermal conductivity high the advantages of.
Nickel porous or nickel foam have been widely used at present battery electrode material, filtration supports, chemical catalyst carrier,
The various fields such as electromagnetic shielding material, noble metal displacement recovery.Using porous matrix foamed plastics, by chemical nickel plating, true
The methods such as empty nickel plating prepare conductive layer, after nickel preplating sulfate plating nickel electrolyte in plating thick nickel, then through calcination, also
Former, annealing operation just can obtain the three-dimensional netted foam nickel material of function admirable.The nickel porous of preparation are adopted this method, its hole
Footpath is generally limited by the aperture of matrix foamed plastics, and aperture is generally larger.
De- alloyage is a kind of method for preparing nano-porous materials, it is also possible to for preparing porous nickel alloy, but this
Method belongs to dealloying corrosion, is typically all to be carried out on metal material top layer for preparing during porous metal material, it is difficult to prepare
Massive material.
The content of the invention
It is an object of the invention to provide a kind of nickel foam prepared with three-dimensional through hole structure or foam nickel-base alloy
Preparation technology.
The present invention specifically provides the preparation method of a kind of nickel foam or foam nickel-base alloy, it is characterised in that：In vacuum
