The invention discloses a high-temperature-resistant AlN and Al2O3 co-reinforced aluminum-base
composite material and a method for preparing the same, and belongs to the technical field of
metal-basecomposite materials. The method includes compressing superfine aluminum
powder until the
porosity of the superfine aluminum
powder is appropriate, loading the superfine aluminum
powder in jackets, sealing the jackets and drilling the peripheries of the jackets to allow an appropriate quantity air to flow into the jackets; placing the jackets in air furnaces, heating the jackets at the low temperatures and thickening oxidation films; increasing the temperatures until the temperatures reach the high temperatures, generating AlN and Al2O3 from
nitrogen and
oxygen in the air,
sintering powder treated at the high temperatures, and carrying out
heat processing on the powder to obtain the high-temperature-resistant AlN and Al2O3 co-reinforced aluminum-base
composite material which is an (AlN+Al2O3) / Al
composite material with excellent high-temperature strength and
heat resistance. The high-temperature-resistant AlN and Al2O3 co-reinforced aluminum-base composite material and the method have the advantages that the air is used as
oxygen and
nitrogen sources, and complicated equipment can be omitted; risks such as aluminum powder
combustion can be prevented, the quantities of
oxide and
nitride can be easily regulated and controlled, and the high-temperature-resistant AlN and Al2O3 co-reinforced aluminum-base composite material and the method are short in period, low in cost, easy to control and suitable for large-scale industrial preparation.
