In the Ti6A14U alloy, the corrosion rate is increased by 48.5 using the oxidized titanium hydride powder; 61.35 and 58.1% less than titanium BT1-0 in 10-, 20- and 30% aqueous solutions, respectively. Nitrogenation by one to three orders of magnitude reduces the corrosion rate of the consolidated material, and the effectiveness of such anti-corrosion protection for samples synthesized from oxidized powdered raw materials is higher, especially for titanium BT1-0 (twice).
