Paper Title:
Cyclic Oxidation Behavior of Sputtered Nanocrystalline Coating with Yttrium Additions in Air
  Abstract

K38 nanocrystalline coatings with various amounts of yttrium addition were deposited by magnetron sputtering. Cyclic oxidation tests were conducted at 800-1000oC in air in order to reveal the effect of reactive elements on the oxidation behavior of nanocrystalline material. The results indicated that the influence of yttrium was not observable at 800oC. At 900 and 1000oC, addition of 0.1 wt.% Y decreased the growth rate of scale, while 0.5 wt.% Y addition significantly increased the oxidation rate of nanocrystalline coating.
