  • Repair and fabrication of combustion turbine components by spark plasma sintering
    Patent number: 6384365
    Abstract: A method of consolidating or repairing turbine component parts, such as turbine blades (10), requires providing a turbine component part (60, 61, 62, 63), establishing a contact pressure between the opposing surfaces (40, 42), where, optionally, fine particles may be present between such surfaces (40, 42), and then generating an electrical field to provide heat, and applying pressure on the opposing surfaces, resulting in high temperature spark plasma sintering to provide a consolidated turbine blade (50).
