| Abstract [eng] |
The oxidation of titanium substrates in the air under laser irradiation is investigated. The experimental dependence of TiO2 layer thickness on the number of laser pulses is subjected to the comprehensive analysis. The prevailing chemical and physical processes on the substrate surface and in the near-surface layer are determined. It is found that the laser irradiation drives the surface-energy induced mixing in the near-surface layer of titanium substrates. The mixing rate sharply depends on temperature. This allowed to detect the exothermic phase transition from anatase to rutile in the titanium dioxide films using ex-situ experimental measurements. |
