A method was proposed for increasing the oxidation resistance of promising wrought Ti2AlNb ortho-alloys by depositing γ-TiAl-based coatings. Using original vacuum pulse-arc melting 100 μm thick granule layers, coatings with different Al/Ti ratios and a thickness 50–60 µm were obtained on surface Ti50Al25Nb25 alloy. Granules Ti50Al44Nb4.9Mo1B0.1 (at.%), 20–60 in size, employed. To vary Al content, initial granules their mixture powder used. Excellent adhesion is ensured similar chemical...
This work aimed to study the oxidation resistance of γ-TiAl based alloy, doped with small concentrations carbon, silicon, and yttrium oxide in air at 800 1100 °C for 30 h. The TNM-B1 alloy samples were produced via high-energy ball milling, self-propagating high-temperature synthesis, hot isostatic pressing techniques. microstructure, kinetics 800–1100 °C, scale structure, mechanism studied. alloys modified carbon silicon was characterized by formation a three-layer coating. Y2O3 performed...
Modern Russian steelmaking plants use predominantly alumina-containing materials for liquefying lime in a ladle-furnace unit, which replaced fluorspar. Alumina-containing currently available on the market cannot be used directly without preliminary preparation (refining, heat treatment or briquetting), are simply unsuitable ladle processing of steel. This work describes laboratory studies production refining fluxes by sintering units such as machines pellets firing producing agglomerate (in...
