Material system for repairing thermal barrier coating and method thereof
A method for repairing a thermal barrier coating (140) deposited on a component (100) having a localized exfoliation (150) of the thermal barrier coating (140), the method comprising: depositing a primer slurry on a thermally grown oxide (132) of the component (100) exposed due to the localized exfoliation (150); depositing a ceramic slurry on the primer slurry; and heating the primer slurry and the ceramic slurry. The primer slurry includes a primer including at least one of a metal and a metal oxide. The ceramic slurry includes a ceramic material, a ceramic slurry binder material, and a ceramic slurry fluid carrier. Heating the primer slurry and the ceramic slurry forms a first chemical bond (210) between the primer and a thermally grown oxide (132) and a second chemical bond (230) between the primer and the ceramic material.
用于修复沉积在部件(100)上的热障涂层(140)的方法，所述部件(100)具有热障涂层(140)的局部剥落(150)，所述方法包括：在由于局部剥落(150)而暴露的部件(100)的热生长氧化物(132)上沉积底漆浆料；在底漆浆料上沉积陶瓷浆料；以及加热底漆浆料和陶瓷浆料。所述底漆浆料包含含有金属和金属氧化物中的至少一种的底漆。所述陶瓷浆料包含陶瓷材料、陶瓷浆料粘结剂材料以及陶瓷浆料流体载体。加热底漆浆料和陶瓷浆料在底漆和热生长氧化物(132)之间形成第一化学键(210)，并且在底漆和陶瓷材料之间形成第二化学键(230)。
