The gas transportation SHS-technology of obtaining multicomponent titanium coatings in the mode of thermal self-ignition on iron-carbon alloys is considered. Laws and mechanisms of their formation are investigated. The dependence of the thickness of the coating on the technological parameters of the process (temperature and duration of isothermal aging) has been experimentally established. With the help of methods of mathematical modeling, optimal compositions of SHS-mixtures for the application of complex coatings have been developed. The influence of composition of reaction mixtures on the properties of the obtained coatings is studied. In order to analyze the process of formation of complex coatings on the basis of titanium in the conditions of SHS, the equilibrium state of reaction products in multicomponent powder systems was performed. Proposed kinetic scheme of chemical transformations is proposed. Installed kinetic and thermophysical patterns of growth of coatings.
