Th. oxidation beh.vior of th. Al Co Cr Fe Ni YTaxh.gh.entropy alloy（h.A） doped with.different Ta contents at 1100 °C is investigated. In th.s study, different reasons for th. spallation of th. oxide scales of h.As with.ut/with.excessive Ta addition after 1000 h.of oxidation are discussed, and th. most suitable Ta doping content for th.s h.A is explored, in wh.ch.th. h.A exh.bits both.an exceptionally low oxidation rate, and th. formation of oxide scales composed of intact a-Al2O3. Meanwh.le, it is found th.t th. addition of Ta can effectively inh.bit th. ph.se transition of β ph.se, wh.ch.makes th. surface of th. oxide scale smooth.r. By combining our experimental results with.Wagner–h.uffe th.ory, th. influence of Ta drag effect on oxide scale growth.is explained, wh.ch.provides some th.oretical guidance for th. subsequent design of Al Co Cr Fe Ni h.As, and can lead to th. development of th.rmal barrier coatings at h.gh.r service temperature.
