Abstract

The invention discloses a preparing method of a Ti2AlC particle reinforced copper base composite, and belongs to the field of composite preparing. The method comprises the specific steps that Ti2AlC particle suspension is prepared; an oxygen-free pure copper plate in the completely annealed state is subject to surface treatment; the dispersed Ti2AlC particle suspension is evenly sprayed to the surfaces of copper plates, the two copper plates are overlapped, fastened, rolled, and cut in half, the above process is repeated few times, Ti2AlC particles are continuously added, and finally, a boardis continuously subject to accumulative roll-bonding at multiple passes. According to the preparing method, dispersion of reinforced particles in a base body can be obviously improved, through the coordinative effect of particle reinforcing, refined crystalline strengthening and work hardening, the hardness and the strength of the composite can be obviously improved, conductive performance is notobviously reduced, and the preparing method is easy to operate, simple in process, low in cost and capable of being produced in batch.

Description

technical field [0001] The invention belongs to the field of composite material preparation, in particular to a Ti 2 Preparation method of AlC particle reinforced copper matrix composite material. Background technique [0002] With the rapid development of industries such as machine manufacturing, electronic communication, rail transit, instrumentation and military industry, people have higher and higher requirements for the strength, electrical conductivity, thermal conductivity and fatigue performance of copper and its alloys. [0003] The strength and wear resistance of the matrix can be effectively enhanced by adding reinforcing phases (ceramic particles, whiskers, fibers, carbon nanotubes, graphene, etc.) to copper and its alloys. In general, the mechanical properties of Cu-based composites increase with the increase of the reinforcement phase content, however, the electrical conductivity of the composite material decreases significantly when the reinforcement phase co...
