Combinatorial Study on Phase Formation and Oxidation in the Thin Film Superalloy Subsystems Co–Al–Cr and Co–Al–Cr–W
journal contribution
posted on 2018-09-20, 00:00 authored by Dennis Naujoks, Martin Weiser, Steffen Salomon, Helge Stein, Sannakaisa Virtanen, Alfred LudwigTwo Co-based superalloy
subsystems, the ternary system Co–Al–Cr
and the quasi-ternary system Co–Al–Cr–W with
a constant amount of 10 at. % W, were deposited as thin-film materials
libraries and analyzed in terms of phase formation and oxidation behavior
at 500 °C in air. By combining energy-dispersive X-ray analysis
and X-ray photoelectron spectroscopy high-throughput composition measurements,
a detailed evaluation of the dependence between the initial multinary
metal composition and the oxide scale composition which is forming
upon oxidation on the surface of the thin film is established. Phase
maps for both materials libraries are provided by high-throughput
X-ray diffraction. In addition, the oxidation of a Co–Al–Cr–W
bulk sample was analyzed and compared to a corresponding film in the
library.
