在确定和开发具有较高温度能力的热障涂层的替代材料时，材料选择指南是可取的。其中一些涉及确定在高温下表现出特别低的热传导值的候选材料，另一些涉及与粘结合金和高温合金上形成的热生长氧化物接触时的热力学稳定性。利用已有的最小导热系数理论，提出了一种材料参数，该参数可用于确定高温应用中氧化钇稳定氧化锆的候选替代物。(C)2002 Elsevier Science B.V.保留所有权利。
Materials selection guidelines are desirable in identifying and developing alternative materials for higher-temperature capability thermal barrier coatings. Some relate to identifying candidate materials that exhibit particularly low values of thermal conductivity at high temperatures and others relate to thermodynamic stability in contact with the thermally grown oxides formed on bondcoat alloys and superalloys. By using existing theories of the minimum thermal conductivity, a materials parameter is developed that can be used to identify candidate alternatives to yttria-stabilized zirconia for high-temperature applications.
