Problems solved by technology

Although this process solves the problem of complex surface treatment, it only improves the corrosion resistance and mechanical properties of porous metals through alternate deposition. When the deposition layer is too thick, the porosity of the material will decrease, so it is difficult to Porous metal materials with high porosity, good corrosion resistance and good mechanical properties are obtained

Description

technical field [0001] The invention relates to the technical field of porous metal materials, in particular to a porous ternary Cu-ZnNi alloy material and its preparation method and application. Background technique [0002] Porous metals are composed of continuous metal phases and pores. Compared with traditional metal materials, their unique pore structure makes porous metals have the characteristics of light weight, large specific surface area, and good energy absorption. According to whether the pores are connected, they can also be divided into open-pore porous metals and closed-pore porous metals. Open-cell porous metal has good properties such as penetration, sound absorption, and heat dissipation, while closed-cell porous metal has the characteristics of low thermal conductivity, strong impact resistance, and high damping. Therefore, porous metals have broad application prospects in chemical industry, machinery, construction, aviation and other fields. [0003] Wh...
