Foam metal processing technology

Abstract

The invention discloses a foam metal processing technology. The foam metal processing technology comprises the steps that an aqueous solution of anionic surfactants, nano conductive carbon slurry andan electroplating solution C are prepared, and a non-metallic insulating foam sponge is cleaned by the aqueous solution containing the anionic surfactants; the cleaned and dried foam sponge is drawn to a material holding groove containing the nano conductive carbon slurry for walk-dipping, then the foam sponge is drawn to a double-roll machine for extrusion, and the extruded dipped foam sponge isdrawn to a hot air drying device for walk-drying; and the dried dipped foam sponge is put into electroplating equipment for electroplating required metal. The foam metal processing technology has a simple preparation process and low processing cost, and the prepared foam metal has higher porosity, more uniform holes, more obvious three-dimensional network structure and lower cost.

Description

technical field

[0001] The invention relates to a metal foam processing technology, which belongs to the technical field of metal foam. Background technique

[0002] Metal foam is a special metal material containing foam pores. Commonly used metal foams include nickel foam, nickel-iron foam, copper foam, copper-iron foam, etc., which have the characteristics of high porosity, large specific surface area and unique three-dimensional network structure. . Metal foam plays an important role in the fields of wave absorption, filtration, catalysis, and energy storage. It is a new type of material that has gradually developed with human science and technology. It is often used in a series of industrial developments such as aerospace and petrochemicals.

[0003] The preparation methods of metal foam mainly include electroplating method, casting method, powder metallurgy method, molten metal foaming method, vapor phase deposition method, etc. Among them, the preparation process of e...
