Based on the background information regarding the irradiation electrochemical effects mentioned earlier, here are several typical practical application examples: Nanosecond laser irradiation improves the corrosion resistance of 17-4PH stainless steel. Laser irradiation can eliminate scratches on the material surface, reduce roughness, and optimize the microstructure; it is more environmentally friendly compared to traditional chemical passivation methods, and it significantly enhances the pitting resistance of stainless steel in environments containing Cl⁻ ions. Highly active oxygen-evolving catalysts prepared by ion beam irradiation: Ar ion irradiation of FeOOH induced a phase transition, resulting in Fe₃O₄ rich in oxygen vacancies; this material exhibited an overpotential of only 353 mV at a current density of 10 mA/cm², showing catalytic activity superior to that of commercial RuO₂. The irradiation electrochemical behavior of stainless steel in reactors: When 1X18H9T steel is irradiated with thermal neutrons, the breakdown potential in sodium chloride solution shifts positively by 100–150 mV; this effect is caused by the accumulation of oxidation products resulting from water dissociation. Electron beam irradiation regulates the electrochemical properties of semiconductor interfaces. Irradiation with electrons of specific energy can eliminate the distortions and hysteresis in the C-V curve of the Al₂O₃-SiO₂ bilayer structure, optimize the charge distribution at the interface, and enhance the electrical stability of the devices.
