Getting filamentary spatial composition with reticulated structure by cluster nickeling of polymer foam

Abstract

A foamy spatial nickel composition with a reticulated structure was obtained by foamed polymer with chemical & galvanic metallization. Some characteristics of the developed filamentary spatial compositions were investigated; it was found that its open porosity is at least 90%, density not exceeding 0.3 g/cm³, and the rate of deposition of nickel reaches 0.5 m/min. The pore size of nickel foam corresponds to the pore size of foamed polymer; microhardness of the deposited nickel is 5000–5500 MPa and compressive strength is 15 MPa. It shows the advantage of nickel spatial composition to the foamed metals, obtained from the foaming of the molten metal, and the proposed field of application for this development.
