“…Because of the potential use of nickel aluminides at high temperatures, it is imperative to understand and study their oxidation behavior. It was reported that the types of scale (oxide or mixture of oxides) and scale morphology formed on the surface of the alloy during high-temperature oxidation/or sulphidation were influenced by both the compositions of the gas and the alloy as well as the reaction temperature [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Both thermodynamic and kinetic factors should be considered to understand this complex corrosion process.…”
