Abstract

The invention discloses a sacrificial anode material containing Sm-Mg alloy. The sacrificial anode material containing the Sm-Mg alloy is composed of, by mass, 8.0%-8.2% of Al, 0.6%-0.8% of Zn, 0.4%-0.6% of Sm, and the balance Mg and inevitable impurities. According to the sacrificial anode material containing the Sm-Mg alloy, consumption is uniform in a corrosive environment, the consumption speed is low, the service life is long, and the sacrificial anode material containing the Sm-Mg alloy is suitable for cathode protection in corrosive environments such as soil, sea water and water heaters, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of magnesium alloy anode materials, and in particular relates to an Sm-containing magnesium alloy sacrificial anode material. Background technique [0002] The economic loss caused by the corrosion of metal materials is huge. Using sacrificial anodes for electrochemical protection is an effective method to prevent metal materials from corroding, and it is of great significance to improve the corrosion resistance and prolong the service life of metal materials. Sacrificial anodes are widely used in anti-corrosion engineering due to their advantages such as no need for external power supply, no interference with adjacent metal facilities, good current dispersion capability, and easy management and maintenance. Magnesium alloys have good electrochemical properties and are often used as sacrificial anode materials to protect the cathode materials of equipment and devices to prolong the service life of cathode ma...
