Using auger electron spectroscopy for studying the composition of the surface of multicomponent alloys under the effect of pulsed laser irradiation

Auger electron spectroscopy was used to study the composition of the oxides formed on the surface of iron-based alloys under pulsed laser irradiation. Laser treatment in air leads to the formation of a multilayer and multicomponent oxide film on the alloy surface. The upper layer of the oxide film c...

Summary:Auger electron spectroscopy was used to study the composition of the oxides formed on the surface of iron-based alloys under pulsed laser irradiation. Laser treatment in air leads to the formation of a multilayer and multicomponent oxide film on the alloy surface. The upper layer of the oxide film consists of local areas of FeO and Fe 2 O 3 and superoxides (Cr, W, Mo) of the doping elements, while the base for the deeper layers consists of Fe 3 O 4 . The laser treatment of tool steels induces a considerable depth redistribution of the doping elements, which affects the composition and depth of the corresponding oxides in the developed film.
