Abstract

This article reports on a new class of amorphous a-Si₃N₄/MeN_x nanocomposite coatings with a high (≥50 vol.%) content of Si₃N₄ phase; here Me=Zr, Ta, Mo and W. These nanocomposites exhibit high (>1000°C) thermal stability against crystallization and high (>1000 °C) oxidation resistance if the metal Me incorporated in the nanocomposite is correctly selected. It was found that the Zr-Si-N film deposited on Si(100) substrate exhibits no increase of the mass (Δm=0) in thermogravimetric measurements performed in flowing air up to 1300 °C, i.e. up to the temperature that is the thermal limit for Si substrate but not for nanocomposite.
