Description
1) 基板との密着性が良好であること
2) 熱膨張係数のミスマッチが少ないこと
3) 緻密でありながら厚さ方向の貫通割れの生じないこと
4) 安価な材料系で構成されること
5) 修復可能な施工プロセスであること
が求められる。
焼結後のコーティングの表面および断面を光学顕微鏡および走査型電子顕微鏡(SEM)で観察した。
インデンテーション法で弾性率を測定した結果、ムライト粉末とアルミナ・シリカゾルバインダを原料とするコーティングの弾性率と比較して、Aは1.61倍、Bは1.76倍の値が得られた。
基板との引張り密着強度はAが33.5MPa、Bが14.5MPaであった。
ふるい分級した8号珪砂(粒径45μm〜53μm、平均約50μm)を1150℃に加熱した試験体に衝突させ、エロージョン試験を行った。粒子投入量は3g、粒子投入時間は2min(砂流量1.5g/min)とし、粒子速度は600m/s、衝突角度は最もエロージョンレートが高いと予測される90deg.とした。
