Solid phase synthesis of coating on the base under the electron beam surfacing

摘要

Two-dimensional model of the Ti-Ni coating synthesis in condition of the electron-beam treatment is suggested and investigated. The base is iron. The system of chemical reactions is written according to the phase diagram of Ti-Ni. The results of numerical investigation of the model which illustrate the role of the technology parameters in the conversion regimes are represented. Distribution of temperature and elements concentration and compounds in different time moments for different synthesis conditions is constructed. It is shown that at any process organization the synthesized material becomes chemically heterogeneous.
