Abstract

The invention discloses a wear-resistant aluminum alloy section and a preparation method thereof. The aluminum alloy material comprises an aluminum alloy substrate and a wear-resistant coating which coats the surface of the aluminum alloy substrate, wherein the wear-resistant coating is prepared from epoxy resin, an abrasive material, filler, a curing agent, a toughening agent, polyoxyethylene alcohol ether, solydimethyl siloxane, carboxymethyl cellulose and benzalacetone in a weight ratio. The preparation method for the wear-resistant aluminum alloy section comprises the following steps: firstly, cleaning and treating the surface of the aluminum alloy substrate; coating the wear-resistant coating, wherein the coating operation comprises the following steps: uniformly coating the surface of the aluminum alloy substrate with the prepared wear-resistant coating; pretreating at the temperature of 80 to 90 DEG C for 10 to 15 minutes; heating to 180 to 200 DEG C; performing thermal treatment for 2 to 3 hours; lastly, naturally cooling to the room temperature to obtain a final product. The wear-resistant aluminum alloy section is simple in process, and has a good friction resisting effect; meanwhile, a formed coating is environment-friendly, and conforms to the environmental protection policy.

Description

technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to a wear-resistant aluminum alloy profile and a preparation method thereof. Background technique [0002] Aluminum alloy is one of the most widely used materials in non-ferrous metals. Aluminum alloy has many excellent properties such as low density, high specific stiffness and specific strength, good plasticity and formability, easy processing, high thermal conductivity and high electrical conductivity. Aerospace, military industry, construction, automobiles, ships and other fields have been successfully applied. In order to reduce weight, reduce energy consumption, improve efficiency and enhance maneuverability, aluminum is used to replace copper or even steel as much as possible. However, aluminum alloys have low hardness, poor wear resistance, and poor corrosion resistance, which limit their applications. At present, the surface treatment of aluminum alloy mainly includ...
