“…Transition metal nitrides are used as anticorrosion and coating materials, 24,25 and the group 4 and 5 metal oxides have high chemical stabilities as well known valve metals. Therefore, group 4 and 5 metal nitrides, oxides and oxynitrides are expected to be stable under an acidic and oxidative atmosphere.…”

Zirconium-based compounds, such as ZrO x N y , have been investigated as a cathode of polymer electrolyte fuel cells. ZrO x N y was prepared using radio-frequency ͑rf͒ magnetron sputtering under an Ar + O 2 + N 2 with heating the substrate. The solubility of ZrO x N y deposited at 500°C was less than 5 ϫ 10 −8 mol dm −3 in 0.1 mol dm −3 H 2 SO 4 at 30°C under atmospheric condition, indicating that ZrO x N y had a high chemical stability in acidic media. The effect of the heat-treatment during the film deposition on the catalytic activity for oxygen reduction reaction ͑ORR͒ and the properties of ZrO x N y has been examined. The ORR current density on ZrO x N y deposited at a substrate temperature of 800°C was ϳ30 times greater than that at 50°C. The dependence of both the ORR current density at 0.4 V and the apparent activation energy of the ORR at 0.4 V on the substrate temperature changed near 500°C. The crystalline structure of ZrO x N y also changed near 500°C. In addition, the catalytic activity for the ORR increased with the increasing crystallinity and decreasing ionization potential of the specimens. Therefore, the crystalline structure, the crystallinity, and the ionization potential might affect the catalytic activity for the ORR.

“…At the same time, higher nitriding temperatures and longer nitriding times cause thicker nitrided layers. It has been reported that TiN is more chemically inert and electrically insulating than titanium alloys [11]. Although the Ti2Ni phase was reported to have a poor corrosion resistance [18], we believe that TiN phase existing in the outermost part of the compound layers makes ion-nitrided TiNi alloys more chemically inert than non-ion-nitrided TiNi alloys.…”
