Abstract

The paper proposed a model of surface modification of a titanium billet by electron beam treatment with using synthesized modifying powders of the Ti-Al-C system. The model takes into account change in the phase composition, heat loss by radiation, melting and shrinking of the powder layer. The change in phase composition is modeled by a detailed reaction scheme. During the calculations it is determined the temperature and concentration fields of pure substances and chemical compounds, effective properties, porosity and layer thickness distributions at different time positions; thermal cycles at specified points of the specimen are analyzed. It is shown that in the result of the modification a heterogeneous multi-phase coating forms from powder layer containing titanium carbide and Max-phase.
