    • Electrostatic deposition of high performance powdered materials [8] onto gas turbine surfaces. The process also includes post-deposition thermal staging of the deposited powder [8] to provide a durable coating that will satisfy the demands of turbine engine operation. The process envisions application of organic-based powdered materials, glass/ceramic powdered materials and metal-based powdered materials and combinations thereof using electrostatic techniques to components [12] exposed to low temperature operations, such as may be found in the front section of a gas turbine engine or to the exterior portions of an aircraft engine, and metal-containing glass ceramics, glass-ceramic materials, or materials that can be transformed into glass ceramic materials, when applied to components [12] exposed to high temperature operations, such as may be found in the turbine and exhaust sections of a gas turbine engine or the flaps of an aircraft.
    • 将高性能粉末材料[8]静电沉积到燃气轮机表面上。 该方法还包括沉积粉末的沉积后分级[8],以提供可满足涡轮发动机运行要求的耐用涂层。 该方法设想使用静电技术将有机基粉末材料,玻璃/陶瓷粉末材料和金属基粉末材料及其组合应用于暴露于低温操作的组分[12],例如可以在 燃气涡轮发动机或飞机发动机的外部部分,以及当应用于暴露于高温操作的部件[12]时,可以转化成玻璃陶瓷材料的含金属玻璃陶瓷,玻璃陶瓷材料或材料,例如 如在燃气涡轮发动机的涡轮机和排气部分或飞行器的翼片中可以看到的那样。
