Abstract
【解決手段】 成膜法は、物品をインダクタに対して位置決めし、物品をインダクタで加熱し、次いで物品に皮膜材料を施工して結晶質皮膜を形成することを含む。物品の加熱は物品の表面の第1の温度を結晶形成に資する第2の温度に上昇させる。別の成膜法は、物品を位置決めし、物品の表面を結晶形成に資する第2の温度に均一に加熱し、次いで物品の表面に耐環境皮膜材料を施工して結晶質耐環境コーティングを形成することを含む。耐環境コーティングの施工は大気プラズマ溶射堆積法によって実施される。被覆物品は、複雑な幾何学形状の物品と、物品の表面に施工された結晶質皮膜とを含む。結晶質皮膜は増大した剥離耐性を有する。
