Abstract
A method of consolidating or repairing turbine component parts, such as turbine blades ( ), requires providing a turbine component part ( ), establishing a contact pressure between the opposing surfaces ( ), where, optionally, fine particles may be present between such surfaces ( ), 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 ( ).
