Abstract. Computational thermodynamic approach is proposed for evaluation of phase-chemical composition of metal surface under laser oxidation in the normal atmosphere, depending on its bulk composition, laser exposure conditions, and composition of the atmosphere. The approach is used for analysis of laser heating of commercial titanium Grade 2 in the air.
