Structural State and Properties of Nitride Coatings Based on the Highly Entropic Alloy Ti30Zr25Nb20Hf15Ta10Y5

详细

The regularities of the formations of nitride coatings based on the base of high entropy multicomponent alloy Ti₃₀Zr₂₅Nb₂₀Hf₁₅Ta₁₀Y₅ 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.
