The optimal test conditions were determined and it was found that pitting mainly initiated at susceptible locations with specific inclusions. After PPT modification, the pitting resistance and protective properties of the oxidation film on 316LN were improved.

Summary: Nickel electrodeposition coating onto a stainless steel AISI 304 substrate was studied using various electrochemical techniques and characterization methods. The results showed that both cyclic voltammetry and linear scan voltammetry led to the formation of a crystalline nickel deposit with different sizes. The coatings exhibited excellent corrosion resistance due to the formation of a passive nickel oxide film in NaOH or NaCl solutions. The atomic force microscopy results indicated the formation of a homogeneous granular film using both electrodeposition techniques. The composition analysis revealed the enrichment of Ni metal, NiO, and Ni(OH)2 in the nickel deposit and passive film.

Summary: In-depth understanding of the tribocorrosion of 316L stainless steel in deep-sea environments is crucial for its application. The study found that the tribocorrosion rate increased with higher hydrostatic pressure, and the passive film formed at higher pressure had lower OH and higher Cl-, leading to increased pitting susceptibility.

Summary: The influence of the native oxide film on passive film properties and localized corrosion of additively manufactured SS 316L was investigated. XPS characterization, electrochemical polarization curves, and SEM morphology analysis were used in 1 wt% HCl. The as-polished sample with the native oxide film showed increased Cr oxidation kinetics, resulting in a more protective and compact film compared to the cathodically-activated sample. Corrosive attack varied between dislocation cell boundaries to cell interiors depending on the initial surface state and polarization conditions. A corrosion mechanism is proposed to explain this variation. Data availability: The datasets generated during and /or analyzed during the current study cannot be shared at this time as the data also forms part of an ongoing study, but are available from the corresponding author on reasonable request.

Summary: This research proposed a mechanistic model for the formation of the thermal oxide film on low Cr stainless steel, and investigated the effects of kinetically and thermodynamically driven phenomena on the growth of a Fe-Cr complex oxide film at 950 degrees C. It was also found that fluoride ions can enter the oxide film and form a complex with Fe, preferentially dissolving hematite islands through a complexation mechanism.

Summary: In this study, corrosion activities of carbon steel B450C and SS 430 in cement extract solution were compared after exposure for 30 days. It was found that SS 430 showed lower corrosion activity than B450C, attributed to its ability to maintain a passive state. Electrochemical impedance spectroscopy revealed that the impedance values of SS 430 increased over time, forming a protective passive layer, while the impedance values of carbon steel initially increased before decreasing, remaining significantly lower than those of stainless steel.

Summary: This research investigates the tribocorrosion behavior of 316L stainless steel in simulated seawater under continuous and intermittent sliding. The study discusses the mechanism of tribocorrosion in terms of wear morphologies, mechanical properties, and chemical composition. The results show that intermittent sliding increases the wear rate, but repeated sliding promotes the generation of a thicker and more compact passive film, which ultimately enhances the wear resistance.

Summary: In this study, the degradation of the passive film on carbon steel under tensile stress was investigated using X-ray photoelectron spectroscopy (XPS). The shedding ratio was proposed as a novel concept to quantify the degradation level of the passive film, and a computational model was derived based on XPS reanalysis. Electrochemical tests confirmed that the shedding ratio increases with applied tensile stress and has an inversely proportional relationship with polarization resistance. Additionally, partial recovery of the passive film degradation was observed after the stress was removed. Overall, the shedding-ratio model based on XPS reanalysis proves to be effective in quantitatively characterizing the degradation level of passive film and warrants further exploration.

Summary: The study on the relaxation process of 316L stainless steel under low oxygen-partial pressured carburizing revealed the formation of surface multilayer with nano-grain carbide. The investigation using electrochemical impedance spectroscopy (EIS) showed that the generation of nano-grain carbide(s) during carburizing deteriorates the electrochemical behavior of the steel. However, steel with higher corrosion resistance tended to have a larger amount of carbide generation due to various factors such as phase, grain size, morphology, and amount of compound formation.

Summary: The effect of methanogenic archaea on the corrosion behavior of 316L stainless steel under different concentrations of organic electron donor was investigated. The results showed that methanogenic archaea can utilize stainless steel as an alternative energy source and promote its corrosion under decreased acetate concentration. Severe pitting corrosion of stainless steel is caused by the secretion of redox-active substances by methanogenic archaea, which has little relationship with the biofilm formed by them.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
