“…There was not phase changed in the Al-Si coating below 573 • C [40]. Due to the hindrance of Si in the Al-Si coating, the interdiffusion between Al atoms and the substrate in the Al-Si coating was very slow [41][42][43][44]. Therefore, the heating rates of 50 • C/s, named rapid heating, can be applied to heating the Al-Si coating at the stage of 20-500 • C which did not significantly influence on the microstructure of the Al-Si coating.…”

In this study, the influence of the multi-step heating methods, such as two-step heating methods and three-step heating methods, on the properties of Al–Si coating boron steel sheet were evaluated by using the Gleeble-3500 thermal simulator. The evolution of microstructure and 3D surface topography of the Al–Si coating were also investigated. The results showed that the heating rates of 50 °C/s, named rapid heating, at the stage of 20–500 °C did not significantly influence the microstructure and 3D surface topography of the Al–Si coating in the two-step heating methods. The results also indicated that the volume fractions of Fe3Al2Si3 intermetallic compound, FeAl intermetallic compound and a-Fe phase in the Al–Si coating reduced by rapid heating at the stage of 700–930 °C in the three-step heating methods. The roughness of 3D surface topography of the Al–Si coating increased by rapid heating at the stage of 700–930 °C. Rapid heating at the stage of 700–930 °C had little influence on the porosity of the Al–Si coating. The results provided a theoretical basis for the popularization and application of rapid heating in the Al–Si coating boron steel sheet.

“…One example is the aluminized steel DX51D AS120 B CO according to the UNE-EN 10346 standard. This flat steel product combines the properties of aluminum, good corrosion resistance, and high thermal conductivity, with the excellent mechanical properties of steel [12]. To aluminize the steel substrate, a thin layer of an aluminum-silicon alloy [13] with a silicon content of 8–11% is fixed on the steel surface by a hot dip process.…”

Many trays and pieces of Al-Mg and aluminized steel are used in the food industry. Sometimes these elements have non-stick coatings to solve problems related to the adhesion of masses and food products. With use, the coatings deteriorate and lose efficiency and must be removed to apply a new coating. The thermal cycles suffered by these alloys during the removal process of the deteriorated coating (500 °C) and the polymerization of a new coating (400 °C) can affect the durability and efficiency of the metallic substrates. The evolution of the mechanical and microstructural properties of the Al-Mg and aluminized steel substrates after two thermal cycles was studied in this work. The following parameters were analyzed: tensile strength, elongation (%), hardness, ASTM grain size, and the nature and distribution of the constituent particles. The report concluded that the removal of the coating, after each cycle, produced a decrease in the mechanical properties of the substrates. The hardness and tensile strength in Al-Mg decreases between 20–27% and in aluminized steel between 10–11%. In both cases, the process does not compromise the reuse of the substrate for the application of a new coating layer. The final blasting stage does not affect the Al-Mg alloys but may affect the aluminized steel Al-Si protective layer if special precautions are not taken.
