Beschreibung
Zusammenfassung:	A novel coating system is provided that allows for a single coating structure to exhibit properties previously considered mutually exclusive. A unique approach for tailoring specific properties of a coating structure as a function of location within the coating is provided with a specially designed undercoat having a columnar macrostructure and a second coating layer that is selected to be compatible with and complement the undercoat. The composite coating system can maintain thermocomechanical compliance while improving various bulk and/or free surface properties of the composite coating system. 提供种新颖涂层体系，所述新颖涂层体系允许单涂层结构显示先前认为互斥的性质。采用具有柱状宏观结构的特别设计的底涂层以及经选择来与所述底涂层相容并且互补的第二涂层，提供了种用于随所述涂层内的位置变化而调整涂层结构的特定性质的独特方法。所得的复合涂层体系可以维持热机械顺应性，同时改善所述复合涂层体系的各种整体(bulk)和/或自由表面性质。
