The development of aluminum-based high-strength nanostructured materials and coatings is essential for advanced surface engineering applications. Their functional properties strongly depend on the technological operations employed during fabrication. This study analyzes the key technological stages involved in producing aluminum-based nanostructured coatings, including substrate preparation, thin film deposition, anodization, and post-treatment processes. Particular attention is paid to the influence of processing parameters on the formation of nanoscale structures and columnar morphologies. The analysis shows that optimization of technological operations allows effective control of structural characteristics, leading to improved hardness, elastic modulus, and mechanical stability of the coatings. The results demonstrate the potential of optimized aluminum-based nanostructured coatings for use in high-performance engineering and protective applications.
