Summary: The galvanic corrosion behavior of the 90/10 Cu-Ni alloy coupled to AISI 316L stainless steel was studied under different temperatures and hydrostatic pressures, showing that both factors have an accelerating effect on the self-corrosion of 90/10 Cu-Ni. The temperature was found to have a more influential effect on the galvanic corrosion process compared to hydrostatic pressure, with a potential relation established between the two factors and the corrosion behavior.

Summary: The study revealed that the sensitivity of AISI 410 stainless steel to intergranular corrosion (IGC) was affected by sensitization heat treatment, with longer tempering time leading to more severe localized attack but also a healing effect. Additionally, electrochemical noise and potentiodynamic electrochemical impedance spectroscopy are useful techniques for investigating the corrosion susceptibility of the alloy.

Summary: Intergranular corrosion is a significant process affecting the behavior of austenitic stainless steels. Factors such as steel composition, prior deformation, and temperature influence the degree of sensitization. Isothermal annealing affects the precipitation of secondary phases, and longer annealing times result in increased amounts of secondary phases. Thermo-Calc software is used to calculate the equilibrium state of secondary phases.

Summary: Corrosion is a major reason for the failure of metallic implants. The presence of bone marrow derived mesenchymal stem cells (BMSCs) can decrease the stability of 316 L stainless steels (316 L SS), leading to preferential pitting corrosion initiation at the peripheries of BMSCs.

Summary: This paper discusses the effect of hydrogen-free active screen plasma nitriding on AISI 316L austenitic stainless steel. The results show that the active screen can form hard diffusion layers at lower temperatures and improve corrosion resistance. However, with longer process time, the corrosion resistance decreases.

Summary: The study investigated the passivation of AISI 316L stainless steel in citric acid solutions with and without H2O2, and how it affected the electronic-semiconducting properties of the passive layers and corrosion resistance of the alloy. Higher passivating current densities were found to lead to lower concentration of charge carriers and improve corrosion performance. However, the addition of H2O2 was associated with deterioration of passive film properties.

Summary: This study aims to explore the effects of transformation-induced plasticity (TRIP) induced by cold rolling on AISI 316L grade ASTM F138: 2019, a biomedical material, and its compliance with ISO 5832. Cold rolling of 316L stainless steel is a cost-effective method that provides good surface finish and dimensional accuracy compared to other manufacturing processes. However, the TRIP effect in cold-worked 316L steel can lead to unwanted phases, limiting its use as a biomaterial. Understanding the TRIP effect through cold rolling can enhance its applicability in biomedical engineering.

Summary: The research found that samples with less internal stress formed denser and less defective passive films on their surfaces, attributed to higher concentration of metal ions at the metal/solution interface during anodization process. Prolonged passivation times resulted in more impurities being incorporated into the growing passive film, deteriorating its electrochemical properties.

Summary: A new method for healing corrosion defects was proposed based on the microarc thermal effect, which has been shown to effectively heal initial corrosion defects and result in a healed microstructure with recrystallized grains. The corrosion performance varies slightly after healing.

Summary: Analysis of irradiation-assisted stress corrosion cracks (IASCCs) in proton-irradiated 316 L stainless steel after constant load test in simulated PWR primary water showed consistent damage with neutron irradiations at similar dose. The microstructural and microchemical features of IASCC cracks were similar to neutron-irradiated samples, indicating the effectiveness of protons in emulating neutron for IASCC study. The preferential oxidation of Si at grain boundaries beyond the crack tip and its dissolution into solution leading to enhanced porosity within the intergranular oxide were identified as important factors behind IASCC in reducing environment.

Summary: The sliding tribocorrosion behaviors of AISI 316 stainless steel in natural seawater environment were influenced by both mechanical effects and electrochemical potential. After conducting tribocorrosion experiments at different potentials, it was found that the lowest coefficient of friction in the wear zone occurred at 0.3V potential.

Summary: During tribocorrosion in NaCl solution, stable corrosion pits with collapsed characteristic were found on 316L stainless steel far below its pitting potential. The collapsed pits were induced by the gradient nano-structured surface (GNSS) formed through surface deformation. High density crystalline defects and dilution of Cr in the topmost region of GNSS caused normal pitting corrosion. Cracking occurred due to local stress concentration at the bottom of the pit. The propagation of the crack crossing the grain boundaries in GNSS by anodic dissolution stress corrosion cracking (SCC) and dissolution of the crack interior led to the collapse of the surface.

Summary: Intergranular corrosion (IGC) is a common form of corrosion in heat exchanger equipment in refineries. This study used various electrochemical measurements to investigate the evolution of IGC and its detection in 304 stainless steel pipes. The results showed that improper onsite operations can lead to rapid IGC development within 15 minutes at 700 degrees C due to chromium carbide precipitates at the grain boundaries. Compared to other methods, electrochemical impedance spectroscopy (EIS) proved to be a nondestructive and effective technique for characterizing the relationship between IGC and microstructure evolution.
