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 anti-corrosion aluminum alloy pipeline. The aluminum alloy pipeline comprises Mg0.2%, Si2.0%, Cu4.0%, Mn0.2%, Fe0.2%, Zr0.1% by weight percentage , Er0.1%, Cr0.01%, Ni0.01%, Ti0.1%, Al balance. The aluminum alloy pipeline is through (1) smelting; (2) adding Al-5Ti-B, Al-lOSr and RE three kinds of metal refinement modifiers to add refinement modifiers; (3) standing for 2h under the condition of 100MPa Forming an ingot; (4) Five hot rolling, three cold rolling under ultrasonic vibration; (5) C and V laser modification and (6) Octadecyl trichlorosilane solution surface treatment to obtain a finished product. The invention utilizes multiple means to modify and process the material of the aluminum alloy pipe, so that the aluminum alloy pipe can still maintain the integrity of the oxide film when corroded under severe working conditions, avoid metal failure, and meet the requirements of today's industrial development.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to a novel high-strength corrosion-resistant aluminum alloy pipeline. 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 development of...
