Abstract
Glass lining and CVD (chemical vapor deposition) YSZ (yttria stabilized zirconia) coating were applied to improve the corrosion resistance of Hastelloy-XR alloy in an Ar-SO2 atmosphere (PSO2 = 10kPa). A glass lining with the composition of 48 SiO2-8 B2O3-6 Al2O3-11 CaO-25 BaO-2 ZnO (mass%) which protected the alloy substrate showed almost no crystallization and mass change below 1073K, but suffered degradation at temperatures over 1173 K. The YSZ (8 mol% Y2O3) coating had a well-grown columnar structure and showed excellent corrosion resistance at 1273 K.
