Abstract

The invention provides a high-efficiency uniform metal infiltrated copper composite material and a preparation method thereof. The method comprises: vacuum drying commercially available metal powder to obtain dried metal powder; and performing vertical fluidized bed crushing on the dried metal powder and grading treatment to obtain metal powder; press the processed metal powder to obtain a metal compact; put the metal compact in a furnace for sintering, and then obtain a metal sintered skeleton; conduct a copper infiltration treatment on the metal sintered skeleton to obtain a metal infiltration copper composite. Solve the problem that in the preparation method of the existing metal copper-infiltrated composite materials, on the one hand, due to the wide distribution and agglomeration of the commercially available metal powder, the uniformity and consistency of the prepared metal skeleton are poor; on the other hand, the metal skeleton is copper-infiltrated During the process, the uniformity and consistency of the metal skeleton copper infiltration cannot be guaranteed, which leads to the technical problem of poor uniformity and consistency of the metal copper infiltration composite material.
