Abstract
Abstract—Samples made of titanium grade BT 1-0 in the form of disks were subjected to isothermal aging at 875°C with access to atmospheric air for 2, 4, 6, 7, and 13 days. As a result of XRD, it was established that the oxide layer is rutile TiO2. The metal blank absorbs oxygen and nitrogen from atmospheric air, which are concentrated in the surface layer. The increase in the mass of oxygen going to the formation of rutile is 96–98 wt % of the total amount of gas absorbed. The rest of the absorbed gas (2–4 wt %) is contained in the metal blank in the form of solid solutions. The gas absorption rate of a titanium blank is proportional to the rate of rutile formation. The process kinetics for each of the sample surfaces (side and end), which is described by an exponential law, is determined. At the initial stage of the oxidation process, the surface geometry does not affect the rate of formation of the ceramic layer of rutile; subsequently, there is an “acceleration” of rutile growth on the end surface.
