Mechanical properties of chromia scales

Abstract
Depth-sensing submicron indentation testing was used to measure the elastic-plastic behavior of sintered chromia and oxide scales formed on pure chromium in air. The use of top-down indentations limited the amount and precision of the scale data due to surface roughness and substrate effects. Nevertheless, results for the hardnesses and elastic moduli were within the range expected for such oxides. Within experimental uncertainty, the mechanical properties of the scales and those of the corresponding bulk oxide were generally comparable.
