Summary: The corrosion-fatigue behavior of friction stir welded AA2024-T3 in a 3.5% NaCl solution was investigated. Corrosion-damage analysis revealed that the heat-affected zone in the shoulder-affected region was more susceptible to corrosion attack due to microstructural coarsening. A mechanism was proposed for the microstructural evolution in the shoulder-affected zone. A significant reduction in the fatigue life of the welded component was observed in the 3.5% NaCl solution compared to laboratory air, attributed to pit formation caused by the dissolution of Al-matrix near intermetallic particles.

Summary: This study investigates the microstructure and intergranular corrosion behavior of 2024 alloy with varying Cu and Mg content. It is found that theta (Al2Cu) and S (Al2CuMg) particles precipitate along grain boundaries after quenching. The presence of these particles greatly affects the intergranular corrosion susceptibility. The alloy's resistance to intergranular corrosion decreases with higher Cu and Mg contents.

Summary: The aeronautic industry is facing challenges in the lifetime, weight, and accuracy of aircraft skins to meet strict requirements. Mechanical milling is replacing chemical milling for aluminum alloy skin parts. Flexible and reconfigurable vacuum holding fixtures are used, but their deployment is limited by the low stiffness of parts. The reduction of mass and stiffness during milling affects natural frequencies and thickness, and a new cutting force model for flexible fixtures is proposed.

Summary: Chromic acid anodizing (CAA) is still commonly used in the aeronautic industry for corrosion protection, but Ce-containing sulfuric acid anodizing (SAA) has been identified as a promising alternative. This study found that thin sulfuric acid anodizing (TSAA) films containing Ce formed at low current density can approach the performance of CAA.

Summary: The influence of metal cations on the corrosion behavior of AA2024-T3 aluminum alloy in model freshwater was investigated. Immersion experiments, surface analysis, and electrochemical measurements were conducted. The corrosion rate of AA2024-T3 decreased as the corrosion indicator Y increased after long-term immersion, and the presence of Zn2+ reduced the corrosion rate of the alloy. Scanning electron microscopy (SEM) observations revealed fewer corrosion products for the specimens immersed in Zn2+-containing solution. X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) showed the attachment of Zn2+ to aluminum alloys, forming protective layers. Furthermore, electrochemical impedance spectroscopy (EIS) results indicated that Zn2+ reduced the area of defects in the passive film.

Summary: The Ocimum basilicium seeds extract (OBSE) was used as an antioxidant and ecological inhibitor against corrosion of 2024-T3 aluminum alloy in 3 wt% NaCl solution. The study showed that increasing the concentration of OBSE can significantly improve the corrosion inhibition efficiency, and through mixed inhibition control, the corrosion process is delayed.

Summary: This study evaluated the properties of Si/DLC coatings deposited by PECVD technique, including microstructure, mechanical, and electrochemical properties. Tetramethylsilane and acetylene were used as precursor gases. The coating showed improved corrosion resistance with increased deposition time, attributed to the growth of coating thickness and fewer film defects. The Si/DLC film failure mechanism was suggested.

Summary: This study investigated corrosion phenomena associated with tinplate cans exposed to different aqueous solutions commonly found in canned tomato products. The presence of cysteine, an amino acid, and/or nitrate were found to correlate strongly with degradation of the coating, while storage of chloride, nitrate, and thiosulfate ions in cans with bisphenol A (BPA) not intentionally added (BPA-NI) led to extensive blister formation. Additionally, volatile sulfur-containing compounds produced during sterilization may be the origin of headspace blackening in protein-containing foods.
