Abstract
Comprehensive studies of nanocomposite coatings in the Mo–Hf–La–Si–B system with different lanthanum content have been carried out. Coatings were obtained by magnetron sputtering of mosaic targets containing Mo–xLa2O3 segments (x = 5, 20, 40%). It is shown that the most effective in terms of increasing hardness, elastic recovery, plasticity index, resistance to elastic deformation, and heat resistance of coatings is the introduction of 3 at % La into their composition.
