The purpose of this study is to clarify high temperature cyclic oxidation behavior of Fe-20Cr-4Al, Fe-20Cr-4Al-0.1 (Y,Pr, Gd, Ho, Ti, Zr), Fe-20Cr-4Al-0.5 (Y,Pr, Gd, Ho, Ti, Zr), Ni-20Cr-1Si and Y-, Y_2O_3-, CeO_2, Al_2O_3-coated Ni-20Cr-1Si alloys. Oxide scale on the Fe-20Cr-4Al and Ni-20Cr-1Si allys spalled during each cooling time. On the other hand, Oxide adherence of the Fe-20Cr-4Al with reactive elements and Y-, Y_2O_3-coated Ni-"20Cr-1Si aloys was markedly improved. It is suggested that good oxide adherence of the Fe-20Cr-4Al alloys with reactive elements is obtained by change of direction of growing oxide on the alloys. Good oxidation resistance of Y- and Y_2O_3-coated Ni-20Cr-1Si alloys may be attributed to the formation of fine and dense Cr_2O_3 on the alloys.

本研究的目的是阐明Fe-20Cr-4Al、Fe-20Cr-4Al-0.1（Y、Pr、Gd、Ho、Ti、Zr）、Fe-20Cr-4Al-0.5（Y 、Pr、Gd、Ho、Ti、Zr)、Ni-20Cr-1Si 和 Y-、Y_2O_3-、CeO_2、Al_2O_3 涂层Ni-20Cr-1Si 合金。 Fe-20Cr-4Al 和 Ni-20Cr-1Si 合金上的氧化皮在每个冷却时间内都会剥落。另一方面，添加活性元素的Fe-20Cr-4Al和Y-、Y_2O_3涂层Ni-"20Cr-1Si合金的氧化物附着力显着提高。这表明Fe-20Cr-4Al合金具有良好的氧化物附着力。 Y-和Y_2O_3涂层Ni-20Cr-1Si合金具有良好的抗氧化性能。这归因于合金上形成了细小致密的Cr_2O_3。
