抄録	In thermal barrier coatings (TBC), failure occurs near or at the interface between the metallic bondcoat and topcoat. During high temperature service an oxide scale consisting mainly of α-alumina forms and is named thermally grown oxide (TGO) along the bond/topcoat interface. For diminishing the creation of thermally grown oxide (TGO), a dense coating with low residual stress and thermal stress buffer layer was preferable. In this study, to deposit such a kind of coating, a gas tunnel type plasma spraying system was utilized to produce an alumina/zirconia functionally graded thermal barrier coating and discussed its physical and mechanical properties, thermal behavior and high temperature oxidation resistance of the coating are discussed. Consequently, the proposed system exhibited superior mechanical properties and oxidation resistance at the expenses of a slightly lower thermal insulating effect. This interlayer is preferred in order to minimize the detrimental effect of the phase transformation of γ-Al₂O₃ to α-Al₂O₃.
