Summary: To better understand the anodic polarization of Mg, a gel electrolyte doped with phenolphthalein was used to avoid convective effects and reveal alkaline zones. This article provides new insights on Mg dissolution when galvanically coupled to AA7075. It has shown that OH- ions generated during Mg dissolution are locally neutralized in the electrolyte and accurately identified the location of Mg(OH)2 compound formation during anodic dissolution.

Summary: This study investigates the corrosion fatigue crack growth (CFCG) in the local zones of A7N01S-T5 aluminum alloy metal inert gas (MIG) welded joints from high-speed train underframes. The results indicate that the base metal (BM) region has the highest rate of CFCG compared to the heat-affected zone (HAZ) and the weld metal (WM) zone. The failure mode of the BM is hydrogen-assisted propagation, while the HAZ and WM exhibit anodic dissolution. The study provides insights into the specific CFCG mechanisms in each zone of aluminum alloy welded joints.

Summary: This study investigates the failure of transpassive films on transition metal alloys and finds that the failure of the film on nickel-based superalloy is mainly due to cracking on niobium-segregated phases and erosion-induced degradation at the metal/barrier layer interface. The study also reveals the formation of a bi-layer structure in the transpassive film after secondary passivation.

Summary: The application of corrosion inhibitors is a feasible way to protect metals from corrosion reactions. The use of organic corrosion inhibitors has significant drawbacks, such as toxicity to the environment, which has led to the exploration of biodegradable and safe alternatives. Plant extracts and wastes contain phytochemicals that can be used as corrosion inhibitors, offering advantages such as being environmentally friendly and low cost.

Summary: Hypoeutectic Al-Si alloys are widely used for their excellent castability, corrosion resistance, and mechanical properties. However, the presence of coarse Si particles limits their corrosion resistance. Additive Manufacturing (AM) processes provide an effective solution to this problem. This study employed Selective Laser Melting (SLM) to produce AlSi10Mg samples using two different growth strategies. The corrosion properties were compared between stress relief thermal treatment and growth strategy for alloy manufacturing.

Summary: The research examined an additively manufactured aluminium alloy with high solute content, Al-14Zn-3Mg, which showed lower corrosion rate compared to a conventional wrought alloy, AA7075-T6. This difference was attributed to the microstructure and solute content of Al-14Zn-3Mg, specifically the absence of coarse intermetallic particles. Various tests were conducted to analyze the corrosion behavior of this new alloy manufactured through LPBF.

Summary: The study found that square wave polarization (SWP) with alternative stages of pulse current and stable current period plays different roles in stress corrosion cracking (SCC) of pipeline steels. The former mainly contributes to the local anodic dissolution process, while the latter strengthens the cathodic hydrogen evolution process.

Summary: The study investigated the anodic dissolution behaviors of aluminum in AlCl3-[BzMIM]Cl ionic liquid using various electrochemical techniques. Passivation was observed during the process, with an increase in temperature leading to a positive shift in corrosion potential, an increase in corrosion current density, and a decrease in polarisation resistance. Impedance measurements indicated that the anodic dissolution process of aluminum consisted of charge transfer, confinement of the passivated film on the electrode surface, and diffusion-induced Warburg impedance.

Summary: This study investigated the potential of expired paracetamol in preventing copper corrosion in a synthetic acid rain solution, showing that paracetamol can protect copper from dissolution. The binary system of paracetamol and potassium sorbate exhibited higher inhibition efficiency compared to paracetamol alone. Quantum chemical parameters and Gibbs free energy calculations confirmed the inhibitory ability of paracetamol by adsorption on the copper surface.

Summary: Stainless steel 316L, a biomaterial used for medical implants, must be highly resistant to corrosion in the aggressive human body environment. Amino acids like L-Lysine and L-Threonine have been found to act as corrosion inhibitors in artificial body solutions by adsorbing onto steel surfaces. The study also shows that the addition of sodium dodecyl sulphate (SDS) can enhance the adsorption of amino acids on the steel surface, increasing their protection ability against corrosion.

Summary: The research aimed to develop a cheap and non-toxic electrochemical sensor for determining a target analyte and reducing electronic waste. The sensor was prepared using a graphite rod from zinc-carbon batteries and was used to detect L-tryptophan in a Britton-Robinson buffer solution. Two electrochemical methods, differential pulse voltammetry and cyclic voltammetry, were employed in the experiment. The pH value of the support solution, scan rate, and L-tryptophan concentration were found to affect the current response. The oxidation of L-tryptophan was determined to be an irreversible two-electron/two-proton reaction controlled by a mixture of adsorption and diffusion.

Summary: The stability and corrosion resistance of metals are important factors in their applications. Electrochemical measurements have dominant role in studying the behavior of metals due to their efficiency, reliability, speed, cost-effectiveness, and ease of execution. Corrosion inhibitors, particularly environmentally friendly and non-toxic ones, are extensively studied to reduce metals corrosion. Purines, found in biochemical structures like DNA and RNA, are being investigated as potential corrosion inhibitors for various metals and alloys.

Summary: This research focuses on blackberry leaf extract (BLE) as an environmentally friendly corrosion inhibitor for copper in 0.5 M NaCl. High-performance liquid chromatography (HPLC-DAD) was used to identify caffeic acid, quercetin-3-O-glucoside, and kaempferol-3-Oglucoside in BLE. The functional groups of BLE were identified using attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). Electrochemical methods, including potentiodynamic polarization, electrochemical frequency modulation, and electrochemical impedance spectroscopy, show that BLE acts as a mixed type inhibitor with a maximum inhibition efficiency (IE) of 97.19%. The corrosion process is controlled by diffusion when BLE concentration is lower than 15 g/L, and by charge transfer at 15 g/L BLE.
