隔热涂层系统和形成隔热涂层系统的方法
摘要：
本发明公开一种在基材(102)上形成隔热涂层系统(100)的方法，所述方法制备包含给体粉末、活化剂粉末和粘合剂的浆料。给体粉末包括具有高于铝的熔融温度的金属铝合金，粘合剂包括至少一种有机聚合物凝胶。方法进一步包括施加浆料到基材(102)；加热浆料，以形成铝化物粘合涂层(106)，铝化物粘合涂层(106)包含添加铝化物层(108)和布置于基材(102)和添加铝化物层(108)之间的铝化物互扩散区域(110)；并施加隔热涂层(104)到铝化物粘合涂层(106)。隔热涂层(104)可以为致密的垂直破裂隔热涂层(104)，基材(102)可以为燃气涡轮机组件。本发明也公开由这种方法形成的隔热涂层系统(100)。
摘要（英）：

A process for forming a thermal barrier coating system (100) on a substrate (102) is disclosed including preparing a slurry including a donor powder, an activator powder, and a binder. The donor powder includes a metallic aluminum alloy having a melting temperature higher than aluminum, and the binder includes at least one organic polymer gel. The process further includes applying the slurry to the substrate (102), heating the slurry to form an aluminide bond coating (106) including an additive aluminide layer (108) and an aluminide interdiffusion zone (110) disposed between the substrate (102) and the additive aluminide layer (108), and applying a thermal barrier coating (104) to the aluminide bond coating (106). The thermal barrier coating (104) may be a dense vertically-cracked thermal barrier coating (104), and the substrate (102) may be a gas turbine component. Thermal barrier coating systems (100) formed by the process are also disclosed.
