摘要：

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-xLa(2)O(3) 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.
