Description
サーマロン(商標)は、アルミニウム主体のクロム酸塩/リン酸塩接着材料の下塗り層、高温適合性重合樹脂防食被覆材による中塗り層、PTFE(ポリテトラフルオロエチレン)含有の上塗り層を含む、施工厚さが100〜150μmの被覆材料である。サーマロイ(商標)は、高濃度シリコン外層を有するニッケルアルミナイド金属間化合物から成る。サーメテル(商標)は、無機被覆材料の一種であり、金属/セラミックス複合材料複合材料を形成する金属に適用される。サーマガード(商標)は、セラミック結合剤を用いた、アルミニウムを含有する水ベースの被覆材料であり、この場合のポリマーバリヤ層106の施工厚さは、2〜600μmである。前記ポリマーバリヤ層106は、分散液状または粉状で担体(すなわち、ロータアセンブリの露出面全体または特定領域)に施工可能である。その仕組みとは、ポリマー材料を含有する水または溶剤懸濁液を、スプレー法および焼付け法によって前記担体に拡散処理し、それによって形成された層が、前記ポリマー材料の溶融温度を超える環境になると消耗し、犠牲的被覆として前記担体を保護する、というものである。既知の粉末ポリマー材料塗布方法の例として、静電ガン、静電流動床または電着ガンなどを用いた粉末スプレー法や、前記粉末を、ポリマー材料の溶融温度超に熱した担体に吹き付け、塗工層を形成する溶射法、担体を回転させながら炉熱などで担体およびポリマー材料を溶融温度超まで熱し均質な塗工層を形成する「ロトライニング」と呼ばれる方法が挙げられる。
