Problems solved by technology

Although an oxide film is formed on the surface of the aluminum alloy in the natural environment to resist corrosion, the oxide film formed on the surface of the aluminum alloy in the natural environment is about 4nm thick, loose and porous and has an uneven structure. Occurs from the pores of the oxide film, or from the wear of the oxide film, resulting in metal failure, which cannot meet the requirements of today's industrial development

Abstract

The invention discloses a novel high-strength corrosion-resistant aluminum alloy door and window. The novel high-strength corrosion-resistant aluminum alloy door and window comprises an aluminum alloy frame. The aluminum alloy frame comprises, by weight, 0.2% of Mg, 2.0% of Si, 4.0% of Cu, 0.2% of Mn, 0.2% of Fe, 0.1% of Zr, 0.1% of Er, 0.01% of Cr, 0.01% of Ni, 0.1% of Ti, and the balance Al. A finished product is obtained after the aluminum alloy frame is subjected to (1) smelting, (2) adding of three metal refinement modifiers of Al-5Ti-B, Al-10Sr and RE, (3) two hours of standing under the condition of 100 MPa, and forming of a cast ingot, (4) five passes of hot rolling, and three passes of cold rolling under ultrasonic vibration, (5) modification with C laser and V laser, and (6) surface treatment with a octadecyltrichlorosilane solution. According to the novel high-strength corrosion-resistant aluminum alloy door and window, various methods are used for conducting modification and treatment on materials of the aluminum alloy frame, the completeness of an oxidation film can still be kept when the aluminum alloy frame is subjected to corrosion under adverse working conditions, so that metal failure is avoided, and the requirements of current industrial development are met.

Description

technical field [0001] The invention relates to the field of doors and windows, in particular to novel high-strength corrosion-resistant aluminum alloy doors and windows. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. It is divided into 1000 series, 2000 series, 3000 series... 9000 series. In related technologies, the 6000 series aluminum alloys mainly contain two elements of magnesium and silicon, which have the advantages of low melting point, corrosion resistance, heat resistance, wear resistance, easy coating and good processability. However, 6000 series aluminum alloys are rarely With the strength and formability of steel, aluminum alloy cannot completely replace steel to reduce the weight of equipment and reduce energy consumption and pollutant emissions. Moreover, with the...
