Problems solved by technology

Its disadvantages are: 1. The dissolution rate is slow, and the actual electrochemical dissolution mechanism is not clear
[0005] However, the alloy material in this patent application is fixed, the dissolution medium cannot be selected, and the mechanical and physical properties of the material body are poorly adjustable. Therefore, it cannot meet the requirements of people's construction.

Abstract

The invention discloses a rapidly dissolvable non-rare-earth magnesium alloy material and a manufacturing method thereof. The magnesium alloy material is formed by smelting alloy with binary Mg-M, ternary Mg-M-N or multielement phases being balanced. According to the alloy formed in this way, the material electrical resistivity can be controlled, and therefore the dissolution property can be predicted, and dissolution residues cannot influence the subsequent dissolution process. The rapidly dissolvable non-rare-earth magnesium alloy material has the rapidly dissolvable character in a certain medium, rapid dissolution is achieved, the dissolution residues cannot make dissolution be out of control, and the overall environment and dissolution mechanism can be improved.

Description

technical field [0001] The invention belongs to the technical field of metal material production, in particular to a soluble metal material and a preparation method thereof. Background technique [0002] In some special construction environments, in areas that are difficult to reach manually, some special equipment needs to be sent in to complete the work. After the work is completed, the equipment cannot be effectively removed due to various environmental factors. Using dissolvable materials can avoid this limitation and directly explain the disappearance in the environment. Therefore, it is required to use a metal material with a certain mechanical strength, and the body of the metal material can be rapidly degraded or completely dissolved in a certain environmental medium after performing its function. These materials are mostly used in long-distance construction environments that are difficult to touch or operate manually, such as underground engineering, oil productio...
