High-hardness alloy aluminum and production process thereof

Abstract

The invention relates to the technical field of aluminum alloy production, in particular to high-hardness aluminum alloy and a production process thereof. The high-hardness alloy aluminum comprises an alloy aluminum profile base body and a wear-resistant layer, wherein a functional enhancer is melt-injected on the surface of the wear-resistant layer through laser melt-injection; the alloy aluminum profile base body is prepared from the following components in percentage by weight: 0.3 to 0.5 percent of Fe, 0.3 to 0.4 percent of Si, 0.002 to 0.01 percent of Cu, 1.0 to 1.5 percent of Mn, 0.56 to 0.95 percent of Mg, 4.5 to 6.0 percent of Zn, 0.06 to 0.13 percent of Ti, 0.05 to 0.32 percent of Ag, 0.05 to 0.09 percent of Cr, 0.04 to 0.08 percent of V, 0.05 to 0.1 percent of Zr, 0.25 to 0.5 percent of Ni, 0.06 to 1.2 percent of RE and the balance of Al; the alloy aluminum produced through the method has the advantages of being high in hardness and good in strength; and the alloy aluminum product quality is guaranteed, and meanwhile, the probability that the surface of the alloy aluminum product is eroded by microorganisms or bacteria is reduced, so that the service life of the alloy aluminum product is prolonged to a certain extent.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to a high-hardness alloy aluminum and its production process. Background technique [0002] Alloy aluminum plate is to add various alloying elements (main alloying elements are copper, silicon, magnesium, zinc, manganese, secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.) performance and chemical indicators. [0003] Alloy aluminum generally has some special properties that pure aluminum plates do not have, for example: it has relatively good mechanical properties (such as: high hardness, high strength, etc.) and chemical indicators. Therefore, it is widely used in special environments, such as ships, refrigerators, molds, aerospace equipment and other fields. [0004] Although the existing aluminum alloys have certain mechanical properties, their own antibacterial properties are relatively poor, and their mechanical strength is rela...
