Abstract

The evolution of the phase composition of a metal-ceramic material formed by direct laser deposition using synchrotron radiation has been studied. Electron microscopy and X-ray phase analysis demonstrate that active formation of secondary phases of compounds occurs during repeated remelting in the process of multilayer deposition. Insignificant formation of secondary phases occurs during single-track deposition due to the short lifetime of the molten pool. It is established that an increase in the concentration of secondary phases leads to an increase in the material microhardness.
