FOAM OF THE COPPER-ZINC ALLOY WITH EXCELLENT CORROSION RESISTANCE AND THEREOF MANUFACTURING METHOD

摘要

A copper-zinc porous alloy with excellent corrosion resistance which not only improves corrosion resistance and antibacterial deodorizing effect, but also prolongs service life of the copper-zinc porous alloy by alloying zinc into a porous copper metal of three-dimensional network-shaped structure, and a manufacturing method thereof are provided. A copper-zinc porous alloy with excellent corrosion resistance has a three-dimensional network-shaped structure by alloying 15 to 35 wt.% of zinc into a porous copper matrix. A manufacturing method of a copper-zinc porous alloy with excellent corrosion resistance comprises: coating porous copper of a three-dimensional network-shaped structure with a powder mixture comprising 2 to 25 wt.% of zinc or zinc dust powder, 0.5 to 5 wt.% of ammonium chloride(NH4Cl) powder and the balance of alumina(Al2O3) powder; and heating the powder mixture coated porous copper in a temperature range of 350 to 750 deg.C for 10 to 120 minutes to diffuse and infiltrate the powder mixture into the porous copper.
