Abstract

The invention discloses a preparation method of a high-strength fast-dissolving magnesium alloy material, and belongs to the technical field of metal material corrosion. The magnesium alloy material comprises the following components in percentage by weight: 0.5 wt%-8 wt% of Ni, 1 wt%-3 wt% of Cu, 0.5 wt%-4 wt% of Fe, 0.5 wt%-2 wt% of Si, 0.1 wt%-1 wt% of Al, 7.5 wt%-15 wt% of a first quantitative magnesium ingot, 10 wt%-20 wt% of a second quantitative magnesium ingot and the balance of a third quantitative magnesium ingot. In the preparation process, powder and block raw materials are matched, and the adding sequence and the adding proportion of all elements are adjusted, so that the corrosion rate of the magnesium alloy is greatly increased, and the mechanical properties of the tensile strength and the compressive strength of the magnesium alloy within the application field requirement range can be kept.

Description

technical field [0001] The invention belongs to the technical field of metal material corrosion, and in particular relates to a preparation method of high-strength and fast-dissolving magnesium alloy material. Background technique [0002] Magnesium has high chemical activity and is often made into sacrificial anodes and is widely used in sacrificial anodes and corrosion battery anodes. The principle is to connect the magnesium anode to the protected cathode electrode. Since the magnesium anode has high activity and a negative potential than the cathode, the electrons on the anode will continuously transport electrons to the protected cathode through the electrolyte solution, so that the protected cathode is in Negative potential and can be protected. During the corrosion process, the magnesium anode will gradually corrode until it disappears. In the application of corrosion battery and short-term blocking, the corrosion rate of the magnesium anode needs to be large enough...
