Low Temperature Hot Corrosion Screening of Single Crystal Superalloys. [PDF]

open access: yesMaterials (Basel), 2018
Single crystal superalloys were screened in Type II molten (Na,K)-sulfate hot corrosion re-coat tests in air +300 ppm SO2 at 700 °C. They exhibited large 20–40 mg/cm2 weight changes, repeated spallation, and non-protective, 25–50 μm thick corrosion layers after 300 h of testing.
