摘要： A method for repairing a titanium alloy surface of a turbine component includes the step of cold gas-dynamic spraying a powder material comprising at least one titanium alloy directly on the titanium alloy surface. The method may further include the steps of hot isostatic pressing the cold gas-dynamic sprayed turbine component, and performing a separate heat treating step after the hot isostatic pressing. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on compressor turbine components.

摘要： A method is provided for repairing degraded and/or eroded areas on gas turbine blades and vanes. The method is directed to turbine blades and vanes made of advanced superalloy materials with high elevated-temperature properties. The method uses multiple laser beams to perform steps of preheating the repair area, welding the repair area, and post-welding heating of the repaired area. The method uses an array of two or more lasers to perform the steps of heating, welding, and post-weld heat treatment in nearly simultaneous operation thereby dramatically reducing or eliminating the hot cracking associated with other welding methods used with superalloy materials. The method is further directed to cladding or material buildup of degraded turbine blades where the weld material is the same as the matrix or better superalloy materials.
摘要翻译：提供了一种用于修复燃气轮机叶片和叶片上的劣化和/或侵蚀区域的方法。该方法涉及由具有高升温性能的先进超级合金材料制成的涡轮叶片和叶片。该方法使用多个激光束来对维修区域进行预热，修理区域的焊接和修补区域的焊后加热等步骤。该方法使用两个或更多个激光器的阵列在几乎同时的操作中执行加热，焊接和焊后热处理的步骤，从而显着地减少或消除与超级合金材料使用的其它焊接方法相关的热裂纹。该方法进一步涉及劣化涡轮机叶片的覆层或材料堆积，其中焊接材料与基体或更好的超合金材料相同。

摘要： A laser nozzle for use in a laser powder fusion (LPF) welding process provides longer service life and ease of maintenance. Eliminating the use of laser nozzle inserts, the laser nozzle uses an inner tip that is less subject to damage from the welding process. The laser beam travels down an open central passage to exit out the inner tip in focused alignment with a conical powder flow stream ending in a point generally coincident with the laser beam. The powder supply travels through a passage that is generally coaxial to the central laser passage. A circumscribing passage for inert shielding gas or the like is coincidentally coaxial with both the laser powder flow channel and the central laser channel. Coolant is circulated through a main body portion of the nozzle in order to keep the entire assembly cool. Both the laser and the flow of powder may be adjusted according to operating preferences. A porous shielding cover prevents ejecta and other materials from entering into the shielding gas flow channel. The entire assembly is easily constructed from readily available materials and is easily disassembled for cleaning. Reassembly is also easily achieved in order to enable rapid refurbishment and reconstitution of an optimal LPF welding nozzle.
摘要翻译：用于激光粉末熔融（LPF）焊接工艺的激光喷嘴提供更长的使用寿命和易于维护。消除激光喷嘴插件的使用，激光喷嘴使用较少受到焊接过程损坏的内部尖端。激光束沿着打开的中心通道向下移动，以与以与激光束大致重合的点为止的圆锥形粉末流动流聚焦对准地离开内部尖端。粉末供应穿过通常与中心激光通道同轴的通道。用于惰性保护气体等的外接通道与激光粉流路和中心激光通道两者同时同轴。冷却液通过喷嘴的主体部分循环，以便使整个组件保持冷却。可以根据操作偏好来调整激光和粉末的流动。多孔屏蔽罩防止喷射和其他材料进入保护气体流动通道。整个组件可以容易地由易于获得的材料构成，并且易于拆卸以进行清洁。重新组装也很容易实现，以便能够快速翻新和重建最佳的LPF焊接喷嘴。
