Abstract

The invention discloses an iron-containing magnesium-based composite material as well as a preparation method and an application thereof. The mass fraction of Fe in the composite material is 0.01 to 10 percent, and the balance is magnesium, and the material density is 1.37 to 2.35g/cm<3>. The preparation method of the iron-containing magnesium-based composite material comprises the following steps: (1) ball milling magnesium powder and iron powder to form a uniform mixture, wherein the mass fraction of the Fe powder in the mixture is 0.01 to 10 percent, and the balance is magnesium powder; (2) placing the uniform mixture processed in the step 1 into a forming mold, and pre-pressing and forming under the conditions that the temperature is 25 to 150 DEG C and the pressure is 50 to 300 MPa; and (3) sintering the material pressed and formed in the step (2) under the argon protection condition, wherein the sintering temperature is 580 to 600 DEG C, the sintering time is 2 to 5 hours, and the pressure is 100 to 300 MPa. The iron-containing magnesium-based composite material can be used as a hydrogen evolution reaction raw material and a fracturing ball during the petroleum exploitation process. The iron-containing magnesium-based composite material is simple in preparation process and high in hydrogen generation and dissolving rate; and moreover, the hydrogen generation rate can be controlled by virtue of porosity and the surface area, and the application of the product produces no pollution.

Description

technical field [0001] The invention belongs to the field of magnesium-based composite materials, and in particular relates to an iron-containing magnesium-based composite material and a preparation method and application thereof. Background technique [0002] As the lightest metal material in current engineering applications, magnesium has the advantages of high specific strength, high specific stiffness, good shock absorption and thermal conductivity, and is often used in aerospace, automobile and other fields. However, magnesium-based composite materials are extremely easy to be corroded because the potential of the magnesium electrode is low. When in contact with other metals, magnesium generally acts as an anode to undergo galvanic corrosion. During the corrosion process, hydrogen gas is generated and a large amount of heat is released. Hydrogen is used as a clean fuel, and the gas emitted during combustion is water. It has no pollution to nature, and the energy release...
