Title:
METAL COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/000615
Kind Code:
A1
Abstract:
A metal composite material. The metal composite material is prepared by the following method: providing Mg, Mo, Al, Ni and Ti powder; weighing the Mg, Mo, Al, Ni and Ti powder according to a predetermined chemical formula; performing first-time ball-milling on the weighed Mg, Mo, Al, Ni and Ti powder to obtain first mixed powder; performing vacuum smelting on the first mixed powder to obtain an Mg based alloy ingot; crushing the Mg based alloy ingot; providing a carbon nano tube and graphene powder; performing surface modification on the carbon nano tube and the graphene powder; mixing the crushed Mg based alloy ingot with the surface-modified carbon nano tube and the graphene powder, and performing second-time ball-milling to obtain second mixed powder; performing first-time thermal treatment on the second mixed powder to obtain third mixed powder; and performing second-time hot-pressing sintering on the third mixed powder. The process solves the problems of poor compatibility, easy segregation and unstable properties between nonmetal particles and metal matrix, and prepares a hydrogen storage material which is stable in property, strong in hydrogen storage capacity and suitable for industrial production.
