Tensile stress and creep in thermally grown oxide

Boyd W. Veal , Arvydas P. Paulikas & Peggy Y. Hou

Structural components that operate at high temperatures (for example, turbine blades) rely on thermally grown oxide (TGO), commonly alumina, for corrosion protection. Strains that develop in TGOs during operation can reduce the protectiveness of the TGO.
