Abstract

The invention discloses a graphene strengthening nickel base composite material and a preparing method thereof. The method includes the steps that a reducing agent and nickel sulfate are sequentially added into an oxidized graphene solution; nickel powder prepared through reduction is directly compounded with oxidized graphene in the solution, and oxidized graphene / nickel composite powder is initially obtained; the oxidized graphene / nickel composite powder is dried and restored to obtain graphene / nickel composite powder; and composite blocks, composite wires and composite strips of graphene / nickel are obtained through powder metallurgy, hot extrusion and rolling technologies. Graphene in the composite material is evenly scattered, base and strengthening body interface bonding is good, and the composite material has the excellent physical performance. Meanwhile, the process of the graphene strengthening nickel base composite material and the preparing method is simple, the procedure is easy to control, and large-scale application and production are easy to achieve.

Description

technical field [0001] The invention relates to a method for preparing a metal-based composite material in the field of material technology, in particular to a graphene-reinforced nickel-based composite material and a preparation method thereof. Background technique [0002] In the field of aerospace, high-temperature alloy materials represented by nickel alloys are widely used in the main load-carrying components of aircraft, aero-engines, aviation fire control systems, hot-end components of advanced propulsion systems, and high-temperature key components of other equipment. With the development of the aerospace industry, especially with the development of national defense weapons and equipment in the direction of high performance and high efficiency, actual engineering has higher and higher requirements for the comprehensive performance of high-temperature materials, making it difficult for a single material to meet actual needs. Due to the advantages of good high temperat...
