PROBLEM TO BE SOLVED: To form a vertically cracked thermal barrier coating.SOLUTION: A vertically cracked thermal barrier coating (200) is formed by positioning an article (100) relative to a heat source (102). The article (100) includes a thermal barrier coating (202) disposed on a first surface (204) of a substrate (206), and the substrate (206) includes a second surface (208) distal across the substrate (206) from the first surface (204). Heat is applied locally to a discrete portion (210) of the second surface (208) of the substrate (206). A vertical crack (212) in the thermal barrier coating (202) is formed over the discrete portion (210).SELECTED DRAWING: Figure 1 【課題】垂直亀裂遮熱コーティングを形成する。【解決手段】物品（１００）を熱源（１０２）に対して位置決めし、垂直亀裂遮熱コーティング（２００）を形成する。物品（１００）は、基材（２０６）の第１の表面（２０４）上に配置された遮熱コーティング（２０２）を含み、基材（２０６）は、第１の表面（２０４）から基材（２０６）を越えて遠位の第２の表面（２０８）を含む。熱は、基材（２０６）の第２の表面（２０８）の不連続部分（２１０）に局所的に加えられる。遮熱コーティング（２０２）の垂直亀裂（２１２）は、不連続部分（２１０）の上に形成される。【選択図】図１
