Thermal barrier coating systems and materials |
摘要 |
<p>A new family of ceramic materials is identified having particular utility as thermal insulating or thermal barrier coatings on metallic substrates. The ceramic materials have a pyrochlore structure and are typified by the composition A2B2O7 where A and B are various ions and 0 is oxygen. A may have a positive charge of 3<+> or 2<+> and B may have a positive charge of 4<+> or 5<+>. These materials are characterized by having chemical stability, thermal stability and thermal insulating properties superior to those of currently used thermal barrier ceramics. An example pyrochlore material is lanthanum zirconate. <IMAGE></p> |
