Abstract

Hydrothermal corrosion of thin TiN PVD films (3 μm thickness) at 100 MPa water and 20-800°C temperature range was studied. Noticeable oxidation starts above 200°C and acceleration of oxidation processes takes place in hydrothermal conditions in comparison with airflow oxidation of corresponding PVD films and air oxidation of TiN powders. The formation of Ti_nO_2n-1 homological series phases and regular single crystals in oxide scale were observed. FeTiO₃ ilmenite layer secures high protective properties at 600°C and practically does not contain chromium. Therefore, usual low alloy steel with TiN coating can be used instead superalloy for wet air oxidation system with working temperature up to 600°C.
