Oxidation kinetics and mechanisms of growth of alumina scale on precipitation-hardened Pt–Al–Cr–Ru alloys
Source abstract
Abstract
Abstract To understand the mechanisms of oxidation at different conditions, water-quenched and air-cooled Pt 84 :Al 11 :Cr 3 :Ru 2 (at.%) samples were oxidised in air between 1150 and 1350 °C, for up to 100 h. Well-adhering and protective external α-Al 2 O 3 scales, which are non-uniform in thickness, formed. Parabolic scaling kinetics were established, and Pt 84 :Al 11 :Cr 3 :Ru 2 (at.%) exhibited slower scale growth rates and lower activation energies, compared to most other Pt-, Ni- and Fe-based superalloys. Mechanisms of α-Al 2 O 3 growth were proposed to be mainly by inward diffusion of oxygen along the oxide grain boundaries, with some outward diffusion of aluminium ions along the short circuit paths, such as pores.
