The structural and chemical microinhomogeneity of the high-entropy TiVZrNbHfTa coating is studied. Electron microprobe analysis shows that the content of elements varies within 10 at.% at a distance of several nanometers. The density of (s + d) electrons remains constant. High-resolution electron microscopy used to examine the fine structure found clusters with the size close to the ‘periodicity’ of the chemical inhomogeneity.
