Summary: In this study, two-phase WO3 photoelectrodes with different morphologies were obtained by controlling the concentration of Na2WO4 in the precursor solution, and their performance in photoinduced cathodic protection (CP) was explored. The heterojunctions formed between hexagonal and monoclinic WO3 contribute to the directional separation of photogenerated carriers. Additionally, the ordered growth of WO3 nanorods perpendicular to Ti substrate facilitates the directional transmission of photogenerated carriers, resulting in good photoinduced CP performance.

Summary: There is limited data regarding the corrosion rates of reinforcements in marine conditions. In this study, long-term corrosion rates were examined for both small specimens and large reinforced concrete blocks in direct contact with natural seawater. The small specimens had embedded bars at different cover depths, with corrosion rates measured periodically over a span of 10 to 23 years using the polarization resistance method. The large blocks, which had been semi-buried for approximately 25 years in a tidal area of a beach in Spain, had their corrosion rates measured only four times. Surprisingly, the bars showed no signs of corrosion despite high contamination at a cover depth of 3 cm. Additionally, the statistical distribution of corrosion rates in other marine structures is presented.

Summary: MOF materials are widely used in various fields due to their rich porous structures, stable and continuous pores, and high specific surface area. In this study, two MOFs with similar spatial structures were reported, and the modulation of end microstructures was achieved by varying the F content. The output performance of friction power generation increased with the increase in F content, and the obtained polyacidic ligand materials can be used to construct self-powered corrosion protection systems, effectively protecting metallic materials from corrosion.

Summary: The combination of coatings and cathodic protection is a commonly used method for corrosion protection, but the protection life often falls short of the original design. This study investigated the degradation behavior of epoxy coatings in seawater with the presence of Pseudomonas aeruginosa, and found that Pseudomonas aeruginosa accelerated the degradation of coatings while cathodic protection promoted biofilm formation on the coating surface. The findings shed light on the shorter protection life of organic coatings and provide guidance for selecting suitable coatings with anti-fouling and anti-corrosion properties.

Summary: This paper investigates the deposition of calcareous material on carbon steel through cathodic protection. A Response Surface Methodology (RSM) was used to model the electrodeposition process in ASTM seawater by varying temperature and current density parameters. The compactness of the calcareous deposit was observed at a current density <= 150 mu A/cm2. A minimum current density of 55 mu A/cm2 was required to provide cathodic protection and initiate electrodeposition, effectively inhibiting corrosion. Moreover, the developed RSM models can predict the amount and composition of the material under current density of 55 - 310 mu A/cm2 and temperature of 4 - 25 degrees C.

Summary: The electrochemical behavior of steel used for concrete reinforcement can be either active or passive. It remains passive as long as the concrete environment remains highly alkaline, but carbonation and/or chloride contamination can cause it to become active and corrode. This study proposes a boundary element method for solving 3D periodic cathodic protection problems, with a reduced computation cost through the application of acceleration techniques based on adaptive cross approximation.

Summary: The combination of strengthening and corrosion protection using multi-functional material, such as carbon fiber reinforced polymer (CFRP), has been studied in this paper. It was found that a double protection of CFRP wrapping and impressed current cathodic protection (ICCP) was more effective than epoxy coating or sole CFRP wrapping. The optimal ICCP current density depended on the degree of pre-corrosion, and CFRP wrapping provided greater improvements in charge transfer resistance compared to epoxy coating. This work provides a basis for further optimization of ICCP-strengthening technique for corroded reinforced concrete components.

Summary: In this study, Ti-xFe (x = 3,5,9 wt%) alloys were surface modified by micro-arc oxidation (MAO) to improve their antimicrobial properties and biocompatibility.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
