Description
この実例は、結果として得られるコーティングのヘイズに対する排気流の低減の影響を説明するものである。
この実例では、化学気相成長システムの様々な堆積パラメータを調節し、結果として得られるコーティングのヘイズに対する影響を決定した。表2は、様々な堆積のパラメータ及び測定された特性を示している。
この実例は、結果として得られるコーティングのヘイズに対する入口キャリア・ガスの流速の影響を説明するものである。表3に示すように、サンプル番号5及び6は、異なる入口キャリア・ガスの流速を用いて調製した。サンプル5及び6は、同じ化学物質の流速、12.7cm(5インチ)/分の同じベルト速度、同じ排気送風機の速度、及び同じ水/MBTCの比を用いて堆積させた。変更した唯一のパラメータは、入口キャリア・ガスの流速であった。表3に示すように、高いキャリア・ガスの流速を有するサンプル5は、低い流速を有するサンプルより低いヘイズ(3.21%)を有していた。入口の流速をほぼ半分だけ低減することによって、コーティングの厚さは約25%増大しただけであり、表面抵抗率は約6.6%だけ低下したが、ヘイズは3倍増大した。
