文摘

The reaction of nickel with Na₂SO₄ was studied in an O₂-.1SO₂ atmosphere at 700 °C, conditions typical of type II hot corrosion. The interaction of NiO with the sulfate was thermodynamically analyzed and compared with the dissolution–precipitation process known to occur at higher temperatures. Here the dissolution stage was short-lived due to a positive solubility gradient for Ni2+. The relatively fast growth of a NiO layer above a nickel sulfide layer was attributed to the inward molecular transport of SO₂–SO₃ through the porous NiO. The influence of environmental variables was further assessed by reacting nickel with and without Na₂SO₄ in air and then with no deposit in O₂-.1SO₂. The roles of the deposit and atmosphere on the boundary conditions affecting the oxidation–sulfidation process were discussed on the basis of the observed reaction paths.
