Abstract

Zn_1-xLa_xO film was prepared on SS304 steel surface by using hydrothermal method combined with the following heat treatment. The morphology, structure, composition, oxygen vacancy concentration and semiconductor type of film were determined. The corrosion resistance and resistive switching properties of film were analyzed by electrochemical tests and polarization-immersion experiments. The oxygen vacancy formation energy, surface adsorption energy and diffusion energy barrier of films were calculated by density functional theory (DFT). The experimental results show that the polarization treatment enables Zn_1-xLa_xO films switch between high and low resistance states cyclically and stably, and the excellent corrosion resistance and durability are achieved through resistive switching behavior of films. Polarization treatment can reduce the formation energy and diffusion barrier of oxygen vacancies, promoting the formation of oxygen vacancy conductive filaments in the thin film. Regulating the formation and fracture of oxygen vacancy conductive filaments can achieve cyclic switching between high and low resistance states. The film is in a state of constant repair, preventing the invasion of corrosive media through the formation and annihilation of oxygen vacancies, which provides a novel corrosion protection strategy.
