Description

Clamping type magnesium alloy sacrificial anode

Technical Field

The utility model relates to the technical field of metal corrosion prevention, in particular to a clamping type magnesium alloy sacrificial anode.

Background

The corrosion phenomenon caused by the metal oxide formed by the metal exposed to the natural environment is a necessary process, and huge expenses are needed to repair or replace various metal components with the loss of service performance caused by corrosion every year in the world. Various products or facilities comprising iron or steel members, such as infrastructures like roads, bridges, railways, buildings, etc.; corrosion protection is required for industrial pipelines such as petroleum, natural gas and the like. The research shows that: the costs or expenses for prevention, repair and replacement due to corrosion can be estimated to be 3% to 4% of the GDP in industrialized countries.

The corrosion of metals is due to the loss of electrons due to oxidation of their surfaces, and corrosion protection is usually performed by cathodic protection in order to prevent corrosion of metals. Cathodic protection refers to an electrochemical protection technique in which cathodic current is applied to the metal surface to be protected to polarize the cathode, thereby reducing or even preventing corrosion. Cathodic protection typically includes both impressed current cathodic protection and sacrificial anode cathodic protection. Impressed current cathodic protection requires the use of a forced power source that can be placed in a safe zone when a sufficiently large potential difference exists, so that corrosion of the protected metal can be reduced or prevented, whereas impressed current cathodic protection requires the use of a forced power source, which is costly due to continuous power consumption and high monitoring and maintenance requirements. The sacrificial anode cathode protection is to carry out current on a sacrificial anode material and metal, free electrons are provided through self dissolution and consumption of the sacrificial anode to protect the protected metal, the sacrificial anode material is subjected to continuous corrosion and consumption, and frequent maintenance and replacement are usually required, but the conventional sacrificial anode is generally troublesome to replace, time and labor are wasted in disassembly and assembly, and later-stage replacement work is not facilitated.
