“…The thickening of the coating would lead to the internal melt failing to cool in time, which provided a temperature condition for the conversion of γ-Al 2 O 3 to α-Al 2 O 3 . The chemical reactions that might occur throughout the process are shown in Equations ( 1)- (3).…”

“…Al-Li alloy is extensively used in structural materials, such as fuel tanks, skeletons, and housings in the aerospace industry, due to its properties of low density, high specific strength, and high elastic modulus [1,2]. Al-Li alloy is used with the atmospheric corrosion elements and its workloads tend to occur with intergranular corrosion, stress corrosion, pitting, and spalling damage [3][4][5]. This will seriously affect the properties of Al-Li alloy.…”

Micro arc oxidation (MAO) coatings were prepared on the surface of 2195 Al-Li alloy by adding different amounts of indium sulphate (In 2 (SO 4 ) 3 ) into an electrolyte consisting of silicate and phosphate. The surface, cross section, phase composition, and electrochemical experiments of MAO coatings were analysed. X-ray diffraction results show that the coating was composed of γ-Al 2 O 3 , α-Al 2 O 3 , and In 2 O 3 . The results show that after adding In 2 (SO 4 ) 3 , the discharge holes on the surface of the coating were more uniform and the thickness was also increased. The corrosion resistance of MAO coatings was improved by the addition of In 2 (SO 4 ) 3 .

“…Limited studies currently exist on the microstructural characterization, process parameterization, or property modification of AA2070 alloy, whether primary or secondary. Semenov et al [25] explored corrosion resistance against various aggressive atmospheres, Liu et al [26] investigated the impact of plastic deformation and the addition of small Sc percentages on AA2070 microstructure and mechanical properties, and Staroselsky [27] assessed potential applications of these alloys in the aeronautic and aerospace sectors.…”

Aluminum and its alloys are very versatile materials used in a wide range of applications due to the initial characteristics of pure aluminum and the combination of properties obtained from its blend with other elements. Considering that aluminum is the second-most-produced metal after steel, and that its production will increase over time based on the demand to produce products through conventional and additive methodologies, this will lead to an increase in the energy consumed as well as the footprint of carbon generated. It is for this reason that the generation of competitive aluminum alloys must be approached from secondary sources (recycling). To address these environmental issues, in this work, 2070 aluminum alloy (AA2070) samples were manufactured using secondary aluminum powder and compared with the primary aluminum source. The samples were compacted at 700 MPa and sintered at a different range of temperatures between 525 °C and 575 °C. The study includes thermodynamic modeling, microstructure, and mechanical characterization. Microstructure and phases characterization were carried out via scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis, respectively, whereas the mechanical characterization comprised relative density evaluation, hardness, and flexion tests. Results were compared with the calculation of phase stability using Thermo-Calc software 2020a. Based on the results obtained, it can be concluded that the secondary AA2070 optimal sintered temperature, where the components raised the highest mechanical properties and effective relative density range, is 575 °C. Furthermore, the recycled alloys have similar relative densities and flexural strengths than the corresponding alloys made from primary aluminum powder.
