一种石墨烯-不锈钢复合材料及其制备方法和应用
摘要：
本发明公开了一种石墨烯?不锈钢复合材料及其制备方法和应用。该石墨烯?不锈钢复合材料是由以下方法制备得到的，包括：真空条件下，向用于铸造不锈钢的熔体中以喷雾形式加入石墨烯浆体，搅拌混合，铸造，热处理，即得；其中，复合材料中石墨烯质量为不锈钢质量的1％～10％。本发明提供的石墨烯?不锈钢复合材料，石墨烯浆料以喷雾形式加入到用于铸造不锈钢的熔体中，避免了石墨烯之间的团聚；石墨烯加入熔体中可以起到弥散强化的作用，增加复合材料的硬度、导热性和散热性，所得石墨烯?不锈钢复合材料，硬度大于200HB，导热性、散热性能优良。
摘要（英）：

The invention discloses a graphene-stainless steel composite material and a preparation method and application thereof. The graphene-stainless steel composite material is prepared by the following method; and the method comprises the following steps: under vacuum condition, graphene slurry is added in a melt for casting stainless steel in a spray manner for mixing, casting and heat treatment to obtain the graphene-stainless steel composite material, wherein the mass of graphene in the composite material is 1-10% of the mass of the stainless steel. In the graphene-stainless steel composite material provided by the invention, the graphene slurry is added in the melt for casting the stainless steel in a spray manner, so that the agglomeration among graphene is prevented; the graphene is added in the melt to achieve a dispersion strengthening effect and to improve the hardness, the heat conductivity and the cooling property of the composite material; and the graphene-stainless steel composite material has the hardness of higher than 200 HB, and is excellent in heat conductivity and the cooling property.
