Problems solved by technology

[0004] The low density of graphene, poor dispersion performance, and the thermal stability of the graphene-metal matrix interface are all important factors restricting the research of graphene-metal composites. Therefore, it is difficult to obtain metal-based graphene composites by traditional melting methods.
Due to the large difference in density between graphene and nickel-based superalloys, it is difficult to disperse graphene evenly in superalloy powders by directly mixing graphene with superalloy powders

Abstract

The present invention proposes a method for preparing nickel-based high-temperature ene alloy powder, which uses a planetary ball milling method to prepare nickel-based high-temperature ene alloy powder, aiming at the problems of low graphene density, poor dispersion performance, and easy interface reaction during the preparation of the melt. By using planetary ball milling for superalloy powder, superalloy powder flakes with lamellar structure are prepared, and then the lamellar superalloy powder is added to the graphene solution, and mechanically stirred continuously to make graphene evenly dispersed in the superalloy Then, the graphene / superalloy powder sheet is washed and dried, and finally the graphene / superalloy powder sheet is placed in a stainless steel sheath, and vacuum heating and degassing are carried out to remove the adsorbed gas on the surface of the composite powder, and the prepared Nickel-based high temperature olefin alloy composite powder.

Description

technical field [0001] The invention relates to a method for preparing an alloy powder, in particular to a method for preparing a nickel-based high-temperature alkene alloy powder. Background technique [0002] Graphene has sp 2 The honeycomb-shaped quasi-two-dimensional C atomic crystal of hybrid orbitals was first isolated from graphite by A.K.Geim and K.S. Novoselo in 2004 and can exist stably. It is currently the thinnest material in the world with a thickness of one single atom. Graphene not only has excellent electrical properties (electron mobility as high as 200,000 crn at room temperature 2 V - 1 S -1 ), light weight, good thermal conductivity (3000~5000Wm -1 K -1 ), large specific surface area (2630m 2 g -1 ), its Young's modulus (1100GPa) and fracture strength (125GPa) are also comparable to carbon nanotubes. [0003] Because graphene has high strength, high conductivity, and high specific surface area, it is expected to obtain high-performance composite ...
