Abstract
Cast Ti–44Al–6Nb–2Cr–0.3Si–0.1C alloy having good air-oxidation resistance was corroded under 1 atm of flowing 0.2%SO2/Ar gas at 900-1100 oC for 50-300 h in order to examine its corrosion behavior in a SO2-containing environment, because SO2 is an industrially important by-product in the field of combustion and processing of fossil fuels......

High-temperature Corrosion of CrAlSiN Thin Films in N<sub>2</sub>/0.1%H2S Gas
Muhammad Ali Abro, Junhee Hahn, Dong Bok Lee
Korean J. Met. Mater. 2018;56(4):272-279.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.272

Abstract
Cr25.2Al19.5Si4.7N50.5 thin films were deposited on steel substrates by cathodic arc plasma deposition. They consisted of alternating fcc-Cr(Al)N/hcp-Al(Cr,Si)N nanolayers. They were corroded at 900 and 1000 oC for 5-100 h in N2/0.1%H2S gas atmosphere. Their corrosion mechanism, the structure of the formed scales, and the role of film-constituting elements during.....
