The paper presents a preliminary study on the obtaining of a composite powder by an electrolytic method. The composite powder particles are composed of iron nickel alloy that represents the matrix of the composite, and titanium carbide as the reinforcement. The matrix was obtained by electrolytic co-deposition from pure iron and nickel, in form of consumable electrodes. The titanium carbide powder is in suspension in the electrolyte. By the migration of metallic ions towards the cathode, the iron- nickel alloy is formed and, by simultaneously driving the carbide particles found in the electrolyte onto the cathode, the composite powder is obtained. The resulted composite powders were characterized by optical and electron microscopy. The influence of obtaining conditions over the morphology and structure of composite powders is emphased.

Titanium carbide has been attractive for years an engineering ceramics due to its high hardness, high melting point, and good chemical stability. Similarly, titanium dioxide has excellent anti-microbial ceramic material by photon energy. In this study, the anatase type titanium dioxide layer prepared by oxidation of the titanium carbide powder by high temperature oxidation in air atmosphere was investigated in order to determine the possibility of its photocatalyst materials by radiant energy. TiC powder samples of different grain size were gained by ball mill. These samples were oxidized at room temperature to high temperature. The samples exhibited a steady mass gain with increasing oxidation temperature. Based on the results of the X-ray diffraction analysis, anatase type TiO2 was detected on the titanium carbide samples. It is considered, the titanium carbide showed convension anatase type titanium dioxide layer produced by oxidation.

In this study the structure and properties of surface layers obtained on cp-titanium workpieces by non-vacuum electron beam cladding of titanium carbide powder were investigated. The structure of modified materials was examined by optical microscopy and scanning electron microscopy. It was shown that the cladded layer had a high quality and thickness of about 2.3 mm. The cladded layer microstructure consisted of high-strength titanium carbide crystals distributed in titanium matrix. Morphology of titanium carbide particles and their volume fraction changed in the direction from the surface layer to the heat affected zone. The average microhardness value of the cladded layer was ~500 HV. Surface alloyed layers were of higher wear resistance compared to cp-titanium.
