Abstract
Description
本国際出願は、2016年11月16日に出願された米国特許出願第15/353,429号に対する優先権およびその利益を主張し、その全体があらゆる目的のために参照により本明細書に組み込まれる。
[発明の概要]
[発明が解決しようとする課題]
腐食環境と強力な電界/磁界のこのような組み合わせにより、耐食性絶縁体の必要性が生じる。そのような用途のための最も耐食性に優れた絶縁材料は、酸化イットリウム(「イットリア」としても知られる)のような希土類化合物であることが一般に認められている。残念ながら、希土類化合物は高価であり、機械的に脆弱であるという2つの傾向がある。それ故、業界は、酸化アルミニウムのようなより安価な絶縁体の上に希土類化合物のコーティングを使用する傾向がある。
本開示の実施形態は、半導体処理反応器と共に使用するために構成された耐食性構成要素を含み、該耐食性構成要素は、a)セラミック絶縁基板と、b)該セラミック絶縁基板と結合した耐食性非多孔質層であって、耐食性非多孔質層の総重量に基づいて少なくとも15重量%の希土類化合物を有する組成を有しており、また実質的にマイクロクラックおよび亀裂を含まず、かつ少なくとも約100nmおよび最大約100μmの平均粒径を有する微細構造を特徴とする耐食性非多孔質層とを備える。
(i)60μmダイヤモンド:表面を平らにするために必要に応じて、(ii)15μmダイヤモンド、固定砥粒パッド:2分、(iii)9μmダイヤモンド、ラルゴ(プラスチック)パッド:8分、(iv)3μmダイヤモンド、DAC(ナイロン)パッド:6分、(v)1μmのダイヤモンドの起毛布:3分に従って研磨された(研磨用品はStruers社によって提供された)研磨部分の画像分析によって測定される。「粒径」は、ASTM−E112法により測定される。本明細書で言及される「グリーン」または「未焼結」セラミックは、高温熱処理によって緻密化されていないセラミック材料または粉末を含む。「焼結された」または「共焼結された」とは、焼結を促進するために高温熱処理に曝される1若しくはそれ以上のセラミック材料を指す。「焼結」は、多孔性を徐々になくすことによって材料の輸送および緻密化を促進するための加熱または熱処理プロセスである。焼結プロセスは、制御された微細構造および多孔性を有する物質を製造するために使用される。「コーティング」は、基板、例えば焼結後の基板に適用される層である。「積層体」または「複合積層体」は、例えば焼結などのプロセスを介して接合される層のアセンブリである。「構成要素」は部品または製品である。
60μmダイヤモンド:表面を平らにするために必要に応じて
15μmダイヤモンド、固定砥粒パッド:2分
9μmダイヤモンド、ラルゴ(プラスチック)パッド:8分
3μmダイヤモンド、DAC(ナイロン)パッド:6分
1μmダイヤモンド、起毛布:3分
に従って研磨された(研磨用品はStruers社によって提供された)、研磨部分の画像分析によって測定された。
本開示の多数の変形形態および修正形態を使用することができる。本開示のいくつかの特徴を、その他のものは提供せずに提供することは可能であろう。
