Zusammenfassung:	PROBLEM TO BE SOLVED: To improve heat insulation property, heat cycle durability and erosion resistance, in a thermal barrier coating method, a thermal barrier coating film and a turbine member.SOLUTION: In a thermal barrier coating method having steps for: forming an undercoat layer 23 as a metallic bond layer on a parent metal 22; and forming a dense longitudinal-crack coat layer 24 containing ceramics on the undercoat layer 23, a median size of granularity of thermal spray powder is set as D50=1.0 μm-1.5 μm, and suspension plasma spray coating is performed by using suspension formed by mixing a solvent with the thermal spray powder, to thereby form the dense longitudinal-crack coat layer 24.SELECTED DRAWING: Figure 2 【課題】遮熱コーティング法及び遮熱コーティング膜並びにタービン部材において、遮熱性と熱サイクル耐久性と耐エロージョン性の向上を図る。【解決手段】母材２２上に金属結合層としてのアンダーコート層２３を形成するステップと、アンダーコート層２３上にセラミックを含む緻密縦割れコート層２４を形成するステップとを有し、溶射粉末の粒度のメジアン径をＤ５０＝１．０μｍ〜１．５μｍに設定し、溶射粉末に溶媒を混合した懸濁液を用いてサスペンションプラズマ溶射して緻密縦割れコート層２４を形成する。【選択図】図２
