Reaction of metallic titanium with SiO gas

Abstract

We have studied the silicidation of thin VT 1-00 titanium strips in a gaseous SiO atmosphere at 1350°C. The results demonstrate that silicidation produces a porous layer of Ti₅Si₃O_x particles on the surface of the titanium strips. This is accompanied by the incorporation of oxygen atoms into the crystal lattice of α-titanium, resulting in the formation of an α-Ti〈O_y〉 (0.1 ≤ y ≤ 0.5) solid solution. The thickness of the Ti₅Si₃O_x layer and the oxygen concentration in the α-titanium lattice depend on the silicidation rate and time.
