Abstract

The invention discloses a surface nickel-phosphorus plated graphene reinforced titanium-based composite material, the surface of graphene in the composite material is coated with a nickel-phosphorus layer, and the surface nickel-phosphorus plated graphene is dispersively distributed on the surface of a titanium ball; wherein the graphene is distributed at the grain boundary of the titanium matrix, and the composite material only has diffraction peaks corresponding to the alpha phase and the beta phase of titanium. The invention further discloses a preparation method of the surface nickel-phosphorus plated graphene reinforced titanium-based composite material. According to the composite material, the problem that graphene and titanium easily generate TiC is solved, meanwhile, the dispersity of the graphene is better, the graphene is not prone to damage in the ball milling and sintering process, and therefore the performance of the composite material is improved to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of material preparation, in particular to a surface nickel-phosphorus graphene reinforced titanium-based composite material and a preparation method thereof. Background technique [0002] The development requirements of a new generation of aerospace vehicles with lightweight and high performance make it necessary to improve the comprehensive performance of titanium alloys when applied in this field. In addition, due to the poor thermal conductivity during the processing of titanium alloys, the processing heat cannot be quickly conducted out, which is easy to generate thermal stress and damage the titanium alloy parts. [0003] Graphene (GNFs) is a single atomic layer material composed of sp2-hybridized carbon atoms, due to its excellent properties, such as excellent mechanical properties, high electrical conductivity and excellent thermal conductivity (5 times that of diamond, copper 10 times), and GNFs hav...
