Summary: Limited studies have been conducted on the effect of a magnetic field on the corrosion behavior of steels. Investigating the effect on pipeline material in the oil and gas industries will be beneficial regarding corrosion prediction and control. Results show that the presence of a magnetic field increases the corrosion rate of API 5L X65 carbon steel, with flow velocities and magnetic orientation influencing the anodic corrosion current significantly. This study provides important direction in understanding the combined effect of magnetism and flow on corrosion in pipelines used in the oil and gas industries.

Summary: This article presents a comparative analysis of bond strength tests between hot-dip galvanized and black steel rebars to concrete with and without chlorides. The presence of zinc coating on rebars was found to impact anchorage parameters, and the stiffness of rebar anchorage was significantly higher in chloride contaminated concrete compared to concrete without chlorides.

Summary: The impact of chloride and pH on the passivation and corrosion behavior of Q235 steel in simulated concrete pore solutions was investigated. The results showed that increasing chloride concentration led to decreased corrosion resistance of the passive film. Lower pH values also increased the susceptibility of the passive film to corrosion. Alkaline solutions provided better protection for the steel in the presence of chloride.

Summary: This study investigated the passivation and depassivation properties of Cr-Mo corrosion resistance steel in simulated concrete pore solution. The results showed that CR steel exhibited higher corrosion resistance compared to LC steel. The passive film mainly consisted of metal oxides or hydroxides, and the passivation process could be divided into four steps.

Summary: The influence of non-aqueous solvents on the corrosion behavior of passive alloys is still largely unknown. The corrosion of alloy C-22 was studied in organic aprotic solvents containing various water concentrations of HCl. It was found that C-22 is passive in nearly anhydrous solvents, but passivity breaks down when 0.1M HCl is present, leading to either uniform corrosion or pitting. Residual water can either stimulate or inhibit active dissolution depending on its concentration.

Summary: The study found that OSA can mitigate the corrosion damage of 20SiMn steel and reduce corrosion by inhibiting the excessive growth of SRB. The corrosion rate measured indicates that the presence of SRB accelerates corrosion in a carbonated medium, while OSA can reduce the corrosion rate by controlling SRB growth.

Summary: The crevice corrosion of X70 steel varies in different pH solutions, with pH=2 and pH=12 solutions promoting crevice corrosion while pH=6.8 solution prevents it. The increase of pH and Cl- inside crevice contribute to crevice corrosion in pH=2 solution, while the decrease of pH and increase of Cl- inside crevice lead to crevice corrosion in pH=12 solution.

Summary: This study investigates the chloride-induced non-uniform corrosion of steel in cracked reinforced concrete structures using a five-phase mesoscale model. The model considers realistic aggregate, matrix, steel, early-age crack, and damage zone. A physically-based 3D mesoscale modeling approach is developed to simulate the corrosion process. The study finds that early-age cracks accelerate the diffusion of corrosive agents, and increasing crack width, depth, and length intensifies the corrosion of steel.

Summary: This study provides the first description of the effect of Streptococcus mutans on the surface topography and properties of nanostructured titanium. The results show that bacterial incubation leads to a slight decrease in surface nanoroughness but does not reduce the protection provided by the oxide layer. This highlights the importance of considering titanium microstructure when analyzing its behavior in the presence of carbohydrate-metabolizing bacteria.

Summary: This research determined the initial corrosion time and chloride threshold value of steel bars in saline soil simulation solutions through experimentation. Sulfate and other ions were found to influence the corrosion time and threshold value, and a prediction model was established. The results can provide experimental evidence for the service life prediction of reinforced concrete structures in a saline soil environment.

Summary: A new approach is proposed to predict atmospheric corrosion considering different droplet size distributions and geometries. This method utilizes observed droplet size distributions and contact angles to predict corrosion. A finite element model is solved to obtain the current density as a function of droplet geometry, and the computed corrosion current densities are used to estimate material loss for different droplet size distributions and electrolyte configurations, revealing the extent of the impact of droplet size distribution on atmospheric corrosion.

Summary: This study applies transfer learning to improve long-term atmospheric corrosion predictions by transferring data from controlled environments to uncontrolled outdoor conditions. Among the tested transfer learning methods, freezing the initial layer and fine-tuning others at a lower rate showed the best results. This approach effectively forecasts outdoor corrosion behavior using a limited dataset, addressing data scarcity in machine learning models for atmospheric corrosion.
