Oxidation investigations were made on titanium at 800, 1000, and 1200 deg C in air and in oxygen at various oxygen pressures. The oxide layers produced at 800 deg C are TiO/sub 2/ with the rutiie structure. At 100U and 1200'C more laVers with the rutile structure. At 1000 and 1200 deg more layers are formed. The internal porous layers are TiO, Ti/sub 2/O/sub 3/ and TiO/sub 2/. The exterior, large-grained, porous-free layer is TiO/sub 2/ with a rutile structure. It was established that at 1000 and 1200 deg C the formation site of the TiO/sub 2/ layers is the TiO/sub 2/ gas phase boundary. This was explainable by the fact that both oxygen ions and titanium ions diffuse through the exterior oxide layer. The oxygen uptake of the metallic nuclei in the oxidation was determined bv microhardness measurements and weighing. (tr-auth)
