3. Behavior of the main refractory metals and alloys
3.1 Iron-based alloys
There are metals or related chemical elements whose oxide layer is impermeable and protective. They form a single, stable oxide whose composition is close to that of the stoichiometry; diffusion is therefore difficult, since these oxides only contain point defects due to thermal activation (see above). above); these are silicon, chromium and aluminum, whose oxides are, moreover, stable (with the exception of chromium oxide Cr 2 ...
