Abstract
【解決手段】遮熱コーティングの施工のため、作業室2内でプラズマジェット5を作業室内に導入された基体3の表面に向け発生させ、セラミックコーティング材料をPS−PVDによって基体3の表面に施工する。セラミックコーティング材料は粉末としてプラズマジェットに注入し、部分的に又は完全に蒸発させる。第1の作業ステップでは、注入したセラミックコーティング材料粉末の大部分が蒸発するように設定し、蒸気相から基体表面上に凝縮して、基体表面の材料との混合相を形成する。第2の作業ステップでは、注入する粉末の供給速度を、第1作業ステップの5倍に増大し、粉末の蒸発割合を減少させる。コーティング材料は、異方性微細構造を形成し且つ基体表面に対し実質的に垂直に整列する細長い柱状体の形態で堆積される。
