Abstract

The invention provides high-strength wear-resistant aluminum alloy for electric power fittings. The high-strength wear-resistant aluminum alloy comprises an aluminum alloy body and an electroplating layer. The aluminum alloy body is prepared from Si-Mg-Nb-Ce-Co-Al alloy materials. The electroplating layer is an Al-Zn-Ni-Cu plating layer. The prepared aluminum alloy has excellent conductivity, wear resistance, corrosion resistance and oxidation resistance, the mechanical strength is remarkably improved, the machining performance is good, and the combining force between the electroplating layer and the body is high. By means of the appropriately-added complexing agent, brightening agent and the like, the electroplating effect is effectively improved, and the service life of the aluminum alloy is prolonged.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a high-strength wear-resistant aluminum alloy for electric fittings. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. However, due to the soft surface of the aluminum alloy, if the surface of the aluminum alloy is not treated, it is directly processed and used, which not only affects its service life, but also affects its appearance. For example, the electroless nickel plating layer has excellent comprehensive physical and chemical properties such as uniformity, hardness, wear res...
