Abstract

The invention relates to the technical field of metal-based composite materials, in particular to a continuous SiC fiber-reinforced refractory metal-based composite material based on a nano-multilayer structure and a preparation method and application of the continuous SiC fiber-reinforced refractory metal-based composite material. The transition metal layer is deposited on the surface of the continuous SiC fiber with the carbon coating on the surface, so that the bonding performance of the continuous SiC fiber with the carbon coating on the surface and the subsequently deposited metal nitride layer is effectively improved, and the residual stress is effectively released; and the interface bonding strength of the continuous SiC fiber with the carbon coating on the surface and the nano multi-layer composite refractory metal layer is improved. The nano-multilayer composite refractory metal layer is prepared from the refractory metal elementary substance target materials made of at least two materials, compared with a refractory alloy target material, the temperature of follow-up hot isostatic pressing forming is remarkably reduced, interface reaction and fiber degradation can be inhibited, the selectable types of refractory alloy matrix components are greatly enriched, and the requirements of different application environments on the performance of the composite material can be met and the cost is low.
