Abstract

The invention discloses a processing process of a corrosion-resistant aluminum-magnesium alloy. The corrosion-resistant aluminum-magnesium alloy comprises melt, an additive and a treating agent. Rareearth metal La and alkali metal Be are added to the melt, wherein La and Be can improve the high temperature performance and hot cracking performance of the aluminum-magnesium alloy, the alloy grainsof the aluminum-magnesium alloy can be refined, and the wear resistance of the aluminum-magnesium alloy can be improved. By adding silicon, the fluidity of the aluminum-magnesium alloy can be improved, and the wear resistance of the aluminum-magnesium alloy is improved to a certain degree. Copper and magnesium are adopted as a wild phase to improve the mechanical performance of the aluminum-magnesium alloy. The processing process is reasonable in matching design, technological parameters are optimized, and the strength of an alloy matrix is improved; and meanwhile, the hydrophobicity of a surface film of the alloy matrix is improved, contact of corrosive liquid and the alloy matrix is effectively isolated, the anti-corrosion performance is better, and high practicality is achieved.

Description

technical field [0001] The invention relates to the technical field of alloy processing, in particular to a processing technology of a corrosion-resistant aluminum-magnesium alloy. Background technique [0002] The main element of aluminum-magnesium alloy is aluminum, and a small amount of magnesium or other metal materials are added to strengthen its hardness. Aluminum alloy with Mg as the main added element is also called anti-rust aluminum alloy because of its good corrosion resistance. It is one of the common alloys in our daily life and is widely used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors. [0003] With the advancement and development of science and technology, our research on aluminum-magnesium alloys has become more and more in-depth, and the requirements for the corrosion resistance and strength of aluminum-magnesium alloys have become higher and higher. The strength and strength of aluminum-magnesium alloys on the mark...
