Al 2024-T3 alloy (AA2024) is widely used in the aerospace industry because of its low density and good mechanical strength, this latter property resulting from the addition of alloying elements and thermomechanical treatments that make the microstructure complex, improving the mechanical properties. However, the presence of microstructural constituents with compositions different from the…
Friction stir welding (FSW) was developed in the early 90s, and constituted a major breakthrough for joining Al alloys with high mechanical resistance. The procedure involves the use of a non-consumable rotating tool applied in the regions that must be joined, which are held together by applying a forging pressure. The heating caused by the tool rotation and by the plastic deformation, co…

Corrosion degradation of aluminum alloys used in critical industrial sectors, such as aerospace, challenges structural components' durability. Among these alloys, 2024-T3 stands out because it is widely used in this industry thanks to its mechanical strength. Still, it also suffers accelerated corrosion due to precipitated intermetallics forming local galvanic cells. Anodizing, an electro…
AA2050 aluminum alloy is an aluminum, lithium and copper alloy developed in the latest decades of the past century. Due to its great properties, such as, lower density, higher modulus of elasticity (proportional of the amount of lithium), strength and toughness and good corrosion resistance, this alloy is considered, by specialists, as a natural successor of the nowadays most common alloy…
The high-strength aluminum alloys are widely used in the aircraft industry due to its high strength to density ratio that directly affects fuel consumption and the need of maintenance. Therefore, the Friction Stir Welding (FSW) arises as a great development by removing rivets, fasteners and lap joints areas, consequently, decreasing the aircraft weight. However, during the welding process…
Passivation processes are very important both as a way to afford corrosion protection and also prior to application of painting systems. Industrially many of these processes are based on the use of hexavalent Chromium ions (CrVI+). However, although very efficient, these treatments must be banished from industrial use due to their pollutant and carcinogenic characteristics. The literature…
