ABSTRACT
Electron beam processing of materials is a high-tech process that uses a high-energy electron beam for various types of processing. The report presents some basic aspects of the processing method such as the principle of operation, main applications, and advantages. Titanium carbide coatings, which are widely used in industry due to their exceptional properties, are examined in detail. In this study, the possibilities for modification and improvement of the surface structure and properties of titanium substrates by the formation of composite Ti/TiC layers are presented. The layers were fabricated on the top of a pure titanium substrate. On the top of the Ti plates, a layer of carbon powder with a thickness of 0,4.10-3 m was deposited. The samples were electronbeam processes where the power of the beam was varied from 900 to 1500 W. The phase composition of the experimentally obtained samples was studied by X-ray diffraction technique. The microstructure and elemental composition were investigated by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The results obtained show that the coating formed by the highest value of the electron beam power is characterized by the highest thickness and homogeneity distribution of the alloying carbon element.
