Abstract
Al-C, Cr-C, Al-Cr and Al-Cr-C thin film coatings were sputtered onto Ni-201 substrates. Samples were deposited with 1.0 ± 0.3 mg cm−2 Na2SO4 and exposed to dry air/2 ppm SO2 gas atmosphere, at 700°C for 250 hours. Coated samples had reduced corrosion rates relative to uncoated samples. Al–C and Cr–C coatings were not effective since NiO was the only compound detected on the surfaces; in contrast Cr–Al and Cr–Al–C developed protective layers of Al2O3 and Cr2O3 with Cr–Al–C coated samples having the least corrosion rate.
