“…From this spectrum, the other structures were Fig. 2 [21][22][23][27][28][29]. The XRD patterns of the same specimen measured by the micro-XRD system showed the changes in the chemical structure from the center to the edge of the specimen during an oxidation.…”

“…Ti was chosen as a sample specimen because Ti and its alloys are mainly used as pipeline systems in nuclear reactors due to their excellent corrosion resistance, good mechanical properties and suitable durability characteristics [21][22][23][24]. However, in their native form TiO 2 films have poor mechanical properties and they are easily fractured under fretting and sliding wear conditions.…”

Influence of ammonia on the corrosion behavior of Ti−Al−Zr alloy in 360°C water

The influence of ammonia on the corrosion behavior of Ti-Al-Zr alloy was evaluated in pressurized water at 360°C for 600 days. The results of the corrosion test indicated that the addition of ammonia accelerated the corrosion and hydrogen pickup rates. The oxide scales were composed of a double layer structure, and an inner layer was covered by an outer layer of oxide grains. The XRD studies on the oxide scales showed that the anatase-TiO 2 was continuously transformed into rutile-TiO 2 as the corrosion proceeded. When the same weight gain was considered, the oxide layer grown in water appeared to have a much higher rutile weight fraction than that grown in the ammonia aqueous solution. The deterioration of the corrosion behavior by the ammonia could be mainly attributed to the retardation in the transformation of the oxide structure from a metastable anatase phase to a stable rutile one.
