dc.description.abstract
The high-temperature hot corrosion (HTHC) behavior of Ti₁₋ₓAlₓN-coated c-263 alloy was studied with- and without a Na₂SO₄/MgSO₄ salt mixture at 850 °C in a SOₓ-rich atmosphere. In absence of the salt deposit, both, the bare c-263 alloy and cathodic arc evaporated Ti₁₋ₓAlₓN specimens follow a quasi-cubic corrosion rate. However, when exposed to salt under identical conditions, the rates increase significantly, featuring a compounded parabolic-linear rate law for the c-263 alloy, and a parabolic-like rate behavior for Ti₁₋ₓAlₓN-coated specimens. The rate-determining step of the HTHC mechanism was attributed to a nitride-to-oxide transformation, followed by a sequential fluxing of the formed oxides.
