Abstract: A method for joining engine components includes positioning a first plurality of thermal protection structures across a thermal protection space between a first thermal protection surface and a second thermal protection surface. The first and second engine components are locally joined by forming a first plurality of transient liquid phase (TLP) or partial transient liquid phase (PTLP) bonds along corresponding ones of the first plurality of thermal protection structures between the first thermal protection surface and the second thermal protection surface. The second thermal protection surface is formed from a second surface material different from a first surface material of the first thermal protection surface.

Abstract: A method of removing a ceramic thermal barrier coating system (18). Laser energy (20) is applied to the thermal barrier coating system in the presence of a flux material (22) in order to form a melt (26). Upon removal of the energy, the melt solidifies to from a layer of slag (28) which is more loosely adhered to the underlying metallic substrate (12) than the original thermal barrier coating system. The slag is then broken and released from the substrate with a mechanical process such as grit blasting (30). Sufficient energy may be applied to melt an entire depth of the coating system along with a thin layer (34) of the substrate, thereby forming a refreshed surface (36) on the substrate upon resolidification.

Abstract translation: 一种去除陶瓷热障涂层系统（18）的方法。 为了形成熔体（26），在助焊剂材料（22）的存在下，将激光能量（20）施加到热障涂层系统。 在去除能量时，熔体从比原来的热障涂层系统更松散地粘附到下面的金属基底（12）的熔渣（28）固化。 然后利用诸如喷砂（30）的机械工艺将炉渣从基材上破碎并释放。 可以施加足够的能量以与衬底的薄层（34）一起熔化涂层系统的整个深度，从而在再次固化时在衬底上形成刷新的表面（36）。
