“…5a. It was proposed [29] that an application of light increases the process of corrosion of steel at the initial stage by accelerating the oxidation of Fe to Fe 2þ . When a corrosion product film is formed on the steel electrode surface, the photoaccelerated corrosion is either due to the increase in conductivity of the surface layer or photo-induced dissolution of the layer [30].…”

In this work, the electrochemical corrosion behavior of X80 pipeline steel was investigated in a near-neutral pH solution using electrochemical impedance spectroscopy (EIC) and photo-electrochemical (PEC) measurements as well as X-ray photo-electron spectroscopy (XPS) technique. The effects of hydrogencharging and stress were considered. The results show that the steel is in an active dissolution state, and a layer of corrosion product is formed and deposited on the electrode surface, which is subjected to further oxidation to form ferric oxide and hydroxide. Photo-illumination enhances anodic dissolution of the steel when it is under anodic polarization due to destroying of the corrosion product film. When the steel is under cathodic polarization, the cathodic current density decreases upon laser illumination due to the photo-oxidation of hydrogen atoms generated during cathodic reactions, which behaves as an anodic reaction to offset the cathodic current density. Hydrogen-charging and stress decrease the corrosion resistance of the steel and enhance the dissolution rate of the steel.

“…[12][13][14][15][16] The research about the influence of UV light on corrosion and passive behavior of metals and alloys began in the 1980s. 17 The photo inhibition effects on metal Ni, 10 304 5 and 316 6 stainless steels in neutral chloride solution were firstly reported by Macdonald, Breslin and their collaborators. The effects of the illumination duration 6 and UV light intensity 11 were also investigated.…”

The influence of ultraviolet light (UV, λ = 254 nm) illumination on pitting of AISI 304 stainless steel was investigated using critical pitting chloride concentration (CPCC) measurement. In a H 2 SO 4 solution with a gradually increased chloride ion concentration, the CPCC was measured for AISI 304 samples at 0.65 V SCE and 30 °C under different illumination conditions. Direct UV illumination significantly reduced the CPCC value from 0.286 ± 0.018 M (in the dark) to 0.087 ± 0.008 M. Both the passivation process in pure H 2 SO 4 solution and pit growth in acidic chloride solution were affected by UV illumination. The passive film formed in 0.1 M H 2 SO 4 solution with UV illumination (in which a smaller ratio of metal oxides to metal hydroxides was observed) had a lower corrosion resistance than that formed in the dark, indicating the decreased stability of passive film after UV illumination. In addition, UV illumination also accelerated the pit growth rate of 304 samples in acidic chloride solution. After the CPCC tests, lacy cover and rough edges were observed with pits formed in the dark, while no lacy cover was present for pits developed under UV illumination.
