| Résumé | High temperature oxidation of titanium alloy Ti6242S was studied in air at 560 degrees C up to 10000 h. Oxidation kinetics obeys a parabolic law (k(p) = 8.7 x 10(-15) g(2). cm(-4).s(-1)). Oxygen dissolution in the metal was found to represent between 80 and 90% of the total mass gain. Thin oxide scales are mainly composed of TiO2, in top of which some alumina is present. Titanium nitride was detected as a very thin layer at the outer part of the metallic substrate. Underneath, the oxygen dissolution area was found to reach the maximum brittleness after 1000 h of oxidation. |
