Matrix-type nanostructured columnar composite coatings based on anodic aluminum oxide (Al₂O₃) and tantalum oxide (Ta₂O₅) represent a promising class of functional materials for advanced surface engineering applications. The anodization process enables the formation of ordered Nano porous and columnar structures with a high specific surface area, which can effectively serve as a matrix for composite oxide systems. In this study, the structural and morphological characteristics of anodic Al₂O₃–Ta₂O₅ composite coatings are analyzed, with particular emphasis on the formation of matrix-based nanostructured columnar architectures. The article analyzes the micromechanical properties of matrix nanostructures.
