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 new method for repairing turbine engine components is provided. The method utilizes a cold gas-dynamic spray technique to repair degradation on turbine blades, vanes and other components. In the cold gas-dynamic spray process particles at a temperature below their fusing temperature are accelerated and directed to a target surface on the turbine blade. When the particles strike the target surface, the kinetic energy of the particles is converted into plastic deformation of the particle, causing the particle to form a strong bond with the target surface. Post-spray processing is then performed to consolidate and homogenize the applied materials and restore integrity to the material properties in the repaired turbine component. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on gas turbine components.

摘要： A new method for increasing the durability of a turbine engine is provided. The method utilizes a cold gas-dynamic spray technique to apply wear resistant materials to turbine blades. These wear resistant materials improve the durability of the turbine blades, and thus can improve the overall durability, reliability and performance of the turbine engine themselves. In the cold gas-dynamic spray process particles at a temperature below their fusing temperature are accelerated and directed to a target surface on the turbine blade. When the particles strike the target surface, the kinetic energy of the particles is converted into deformation of the particle, causing the particle to form a strong bond with the target surface. Post-spray processing is then performed to consolidate the coating materials and restore material properties in the turbine blade. Thus, the cold gas-dynamic spray process can apply a coating of wear resistant materials to the turbine blades.

摘要： The present invention provides methods and apparatus to restore a blade leading edge on a gas turbine engine component such as an airfoil of a turbine blisk. The method utilizes welding image technology and power control systems in order to provide effective welding with superalloy materials such as Inconel 713 and Inconel 625. The method includes machining away a damaged leading edge and providing a repaired region through successive depositions of superalloy powder filler through laser fusion welding. Deposition material is added until the repaired region exceeds the original dimensions of the airfoil. The airfoil is then machined and finished to return it to original airfoil dimensions.
