Features of Structure Formation During the Thermal Synthesis of Powders Carbide-Steels from Waste Sludge of Bearing Steels

Institute for Problems of Materials Science NAS of Ukraine, 3, Krzhyzhanovsky Str, Kyiv, Ukraine

The peculiarities of structure and phase composition of the briquettes material obtained by thermal fusion of the mixture consisting of a powder slurry obtained by grinding rollers and cone bearings, titanium hydride and graphite. It was shown that after synthesis at temperatures of 1150÷1200 0С phase composition of the obtained alloy includes mainly phases of titanium carbide, cementite and α-Fe. When boron carbide introduced into the mixture too, the last dissociates during thermal synthesis, resulting along with titanium carbide in the alloy significant content boride phases - TiB, TiB2, Ti2B5 and FeB was identified.
Keywords: carbon, thermal fusion, composite powder, titanium carbide, boron carbide slurry, the diffraction pattern of the phase composition.
