“…Early studies show the passive film on the surface of alloy steel has a certain degree of corrosion protection when it is exposed to sunlight in the atmospheric environment (Sun, 2018; Liang et al , 2010; Xia et al , 2019a). Some scholars have studied the influences of various types of radiation on atmospheric corrosion of metal materials and found the radiation can accelerate the corrosion process of metal materials (Yamashita et al , 2007; Mallégol et al , 2008; Xia et al , 2020). In addition, the corrosion behaviors of Q235 under UV light and darkness was compared through the indoor simulation experiment.…”

Purpose This paper aims to study the effect of ultraviolet (UV) light on the corrosion behavior of BC550 weathering steel in simulated marine atmospheric environment. Design/methodology/approach The effect of UV light on the corrosion behavior of BC550 weathering steel in simulated marine atmospheric environments were investigated by the corrosion weight gain experiment, in situ electrochemical noise, scanning electron microscope and X-ray diffraction. Findings UV light accelerated the corrosion process of BC550 weathering steel in the simulated marine atmospheric environment during the first 168 h. The maximum influence factor of UV light was 0.32, and it was only 0.08 after 168 h of corrosion process. Originality/value As the extension of corrosion time, the thickness and density of the corrosion product layer increased, which weakened the acceleration effect of UV light.
