The study of quasi-crystalline thin films based on aluminum for corrosion protection is a current trend in modern materials and coatings. In recent decades, quasicrystals have attracted the attention of scientists due to their unique physical and chemical properties, which can significantly improve the corrosion resistance of metals.Considering the continuous progress in terahertz technology and material science, terahertz absorbers have received much attention.
This paper presents an absorber film with a lattice structure based on AlCuFe quasicrystal. This film consists of AlCuFe quasicrystal lattice and a gold substrate, which facilitates its processing. The film has three optimal absorption bands in a given frequency range. When the polarization of the incident wave changes, it exhibits ideal absorption properties in one frequency band. The study of the relative impedance showed that it is close to the impedance of free space in the absorption zone, which is consistent with traditional theoretical models. The analysis of the electric field confirms that the absorber film effectively absorbs electromagnetic waves due to resonance effects and has high tuning, significant quality factor and sensitivity. The highest quality factors reach 242, and the refractive sensitivity of each mode exceeds 2700, reaching a maximum of 4032. These properties open up broad prospects for the application of the film in biomedicine and communication technologies.
Thin films formed on the basis of aluminum quasicrystals have high strength and a continuous structure, which makes it difficult for corrosive agents to penetrate. Synthesis of such films is carried out using deposition methods such as magnetron sputtering and laser ablation deposition.
During the experiments, the dependence of corrosion resistance on the composition and thickness of quasi-crystalline films was studied. The results demonstrated increased corrosion resistance compared to traditional coatings. This opens up new horizons for the use of quasi-crystalline technologies in protecting metal structures from destruction, which is of significant importance in industry and construction.
