Abstract
This invention relates to the field of aluminum alloy materials technology, specifically to a corrosion-resistant ceramic aluminum alloy composite material and its preparation method. By weight, it comprises: 100 parts of an alloy matrix, 0.15-0.35 parts of zirconium, 0.25-0.55 parts of rare earth elements (the rare earth elements being a mixture of cerium and lanthanum, with a cerium to lanthanum mass ratio of 5-7:3-5), and 12-20 parts of a first reinforcing phase. Its core innovation lies in constructing a multi-layered coated reinforcing phase, solving three major technical problems in traditional ceramic reinforcing phases: weak interfacial bonding between the ceramic reinforcing phase and aluminum alloy powder, easy interfacial reaction, and poor corrosion resistance. This significantly improves the mechanical properties and corrosion resistance of the composite material.
