Description
Summary:The regularities of the formations of nitride coatings based on the base of high entropy multicomponent alloy Ti 30 Zr 25 Nb 20 Hf 15 Ta 10 Y 5 in the initial state without nitrogen and in nitrogen. The initial material of the alloy is solid solution on the base of the bcc-lattice. At the further sputtering of sample in the atmospheres with different contents of nitrogen the coating forms on the base of fcc-lattice. At the optimal conditions of the sputtering the nitride coating on the base of the highly entopic multicomponent alloy has the hardness at the level of 50 GPa and the reduced elastic modulus 350 GPa.
