Problems solved by technology
Due to the poor hardness and corrosion resistance of the aluminum-magnesium alloy substrate, only a low-temperature hard oxidation mold is formed on the aluminum-magnesium alloy substrate. The thickness of the hard oxidation mold is limited, and it is difficult to meet the high-quality requirements of modern cars.

Embodiment 1
[0011] A preparation method of a wear-resistant and corrosion-resistant aluminum-magnesium alloy material: firstly, a metered amount of aluminum-magnesium alloy (Al-0.9Mg-0.2Si-0.5Y) is added into a crucible, and heated to 651-659°C to form a solid with a volume of about 10%. The corresponding aluminum-magnesium alloy slurry is injected into a mold preheated to 260°C for forming, and the mold is heated by high frequency during forming (select the quenching temperature from 476 to 482°C according to the aluminum-magnesium alloy material to ensure that the initial hardened layer is formed while forming , and then quickly put the formed parts into water to cool to obtain the required parts close to the finished product size; then heat at 530°C for 4.5 hours for fine-grain treatment to obtain the final hardened layer; finally, the hardened layer is oxidized by arc suppression An aluminum-magnesium alloy material is formed by electrolytic water treatment.

Abstract
The invention relates to the metal manufacturing, in particular to an aluminum magnesium alloy material with wear resistance and corrosion resistance, and a preparation method thereof. The method comprises the following steps: firstly pouring the aluminum alloy slurry with 10% of solid phase by volume into a preheated die for molding to form an initial rigidification layer, wherein the high-frequency heating and quenching temperature is from 452 to 510 DEG C during the molding; then performing the grain refining process on the initial rigidification layer at the temperature of 500 to 530 DEG C for 4 to 4.5 hours to obtain the final rigidification layer; finally carrying out micro arc oxidation electrolysis water treatment on the rigidification layer to obtain the aluminum magnesium alloy material. The aluminum magnesium alloy material has the properties of wear resistance and corrosion resistance, low preparation cost, and convenient and simple operation for preparation, and can be widely used in the manufacture of parts for high-performing cars.
Description
technical field [0001] The invention relates to the metal manufacturing industry, in particular to a preparation method of a wear-resistant and corrosion-resistant aluminum-magnesium alloy material. Background technique [0002] The National Planning Commission and the Ministry of Science and Technology jointly issued the "Guidelines for Priority Development of Key Fields of High-tech Industrialization" to determine that the key industries for priority development in the automotive field are mainly concentrated in the auto parts manufacturing industry. The development direction of "miniaturization, light weight and high speed" of the automobile industry provides great opportunities for the development of aluminum-magnesium alloy materials. Since the late 1970s, automobile emission regulations have become increasingly stringent. In order to improve fuel efficiency and reduce emissions, the exhaust temperature of the engine has been continuously increased. In order to improve...
