The article shows that the hardness of most stainless steels is 2-3 times less than high-entropy coatings, which shows the prospect of their use as parts of various industrial structures. Microhardness of metallic glasses, which have a defect-free base, and do not differ from high-entropy coatings. In the article, an equation is obtained that shows that the destruction of the coating is proportional to the surface energy and inversely proportional to the Gibbs energy. For stainless steels, the surface energy is about the same as for high-entropy coatings. The Gibbs energy of high-entropy coatings is 2 times higher than that of stainless steels, which leads to a high hardness of high-entropy coatings, which is observed experimentally.
