The corrosion of metal by radiation is called radiation corrosion. It is a special corrosion phenomenon that occurs when metal is exposed to irradiated corrosive environment. The core mechanism of action can be divided into three categories.: Radiolysis effect radiation will decompose corrosive media such as water and generate strong oxidizing components such as oxygen and hydrogen peroxide, which will accelerate the cathode reaction and move the electrode potential forward. In most cases, it will accelerate the metal corrosion rate. For example, the corrosion rate of No. 20 steel can be increased by 3 to 5 times. Irradiation-Electrochemical Effect: Metal surface atoms absorb radiation energy and become more active, making them more likely to participate in electrochemical reactions, which can increase the corrosion rate of carbon steel and low alloy steel by about 10%. Structural effect radiation will destroy the metal lattice and form defects such as dislocations and cavities. It may also change the structure of the oxide film and speed up the diffusion of oxygen ions, ultimately increasing the corrosion rate of materials such as zirconium alloys and stainless steel by 1.2 to 4.4 times. However, there are also special cases. In certain nickel-chromium alloys, under certain radiation environments, radiation will cause metal atoms to diffuse and fill the corrosion holes, which will instead delay corrosion and achieve a similar self-healing effect.
