“…8 Phase stability of the binary oxides is another issue which limits the compositional tuning to high temperatures. 9,10 Given these complexities, low-temperature compositional tuning at the atomic scale, especially for low dopant concentrations, is very difficult. Moreover, there is very limited understanding of the microscopic processes which can enable tuning of the composition of binary oxides grown on alloy substrates at low temperatures.…”

“…This detrimental effect of Hf reactive element could be called "overdoping" and has observed in other work with Cr and Zr. [37] These results suggest that the Hf reactive element effect in the active bed is beneficial when its amount does not exceed 7 wt.-%, because it increases the coating thickness at the same temperature and deposition time.…”

“…The 2.2%Zr addition to Ni 3 Al-0.1%B increased the oxidation rate greatly, though the scale adherence was increased [3]. These effects of Cr, B and Zr were validated by Klöwer et al [4] and Chuang et al [5,6]. The scales that formed on Ni 3 Al-(0.3~2%)Zr [5], Ni 3 Al-0.1%B-2.2%Zr [3], and Ni 3 Al-8%Cr-1%Zr-0.2%B [6] consisted of NiO, ZrO 2 , α-Al 2 O 3 and NiAl 2 O 4 .…”

“…The scales that formed on Ni 3 Al-(0.3~2%)Zr [5], Ni 3 Al-0.1%B-2.2%Zr [3], and Ni 3 Al-8%Cr-1%Zr-0.2%B [6] consisted of NiO, ZrO 2 , α-Al 2 O 3 and NiAl 2 O 4 . The previous oxidation studies [4][5][6] were focused on the isothermal oxidation behavior of Ni 3 Al alloys having Cr and/or Zr and/or B; however, the oxidation behavior of the present alloy including cyclic oxidation has not yet been adequately studied. This paper aims to investigate the cyclic oxidation behavior of the Ni 3 Al-Cr-Zr-Mo-B alloy between 900 and 1100 o C in air.…”
