Comparison of Na2SO4, K2SO4 and Na2SO4-K2SO4 deposit induced hot corrosion of a β-NiAl coating

Hot corrosion behaviour of a β-NiAl coating induced by Na2SO4, K2SO4, and Na2SO4-K2SO4 deposits was investigated at 700 °C in air + 300 ppm SO2. To provide an insight into the corrosion mechanisms, phase equilibria of the Na2SO4-K2SO4-NiO-SO3 system were calculated using an in-house developed thermo...
