.... Comparative information is presented in Table 2 on the corrosion resistance to fused salts, alkalis, and low-temperature oxides for two different classes of structural ceramics, oxides and nonoxides. The data in Table 2 show that both dense oxides and nonoxides are susceptible to attack at low...

... barrier coating (TBC) is applied. Metals and alloys are known to experience accelerated oxidation when their surfaces are covered with a thin film of fused salt in an oxidizing gas atmosphere at elevated temperatures. This is known as high temperature or “hot” corrosion where a porous non-protective...
