Thermal oxidation of the intermetallic Al3Y surface

Autor: V. A. Kochedykov, N. A. Popov, L. A. Akashev, V. G. Shevchenko

Publikováno v: Russian Metallurgy (Metally). 2013:553-556

The oxidation of the intermetallic Al3Y surface in air at temperatures of 673 and 823 K is studied by ellipsometry. The dependences of the oxide film thickness on the oxidation time are obtained, and the optical constants of oxide films and the inter
