Effect of nitrogen content on high-temperature stability of hard and optically transparent amorphous Hf‒Y‒Si‒B‒C‒N coatings

Popis výsledku v původním jazyce

We study the effect of nitrogen content on functional properties, thermal stability, and oxidation resistance of hard and optically transparent amorphous Hf‒Y‒Si‒B‒C‒N coatings prepared by pulsed magnetron sputtering. Ab-initio simulations are performed to link the experimentally obtained properties with the atomic and electronic structures of the fabricated materials. It is shown that the content of N in the material, varied from subsaturation 46 at.% to saturation 51 at.%, is of significant importance for the optimization of thermal stability and tuning the refractive index and extinction coefficient. We identify an optimum N2 content in the plasma and in turn N content in the coatings which outperform the previously introduced high-temperature material Hf6Y2Si29B12C2N45. The results constitute progress in the efforts to combine multiple functional properties with exceptional (above 1300 °C) thermal stability and oxidation resistance.
