    Abstract: A method of correcting defects in a metal workpeice. A location of a defect in a workpiece is determined. The defect comprising a void or an inclusion in a workpiece substrate. The workpiece substrate is comprised of a metal alloy. Material of the workpiece substrate at the location of the defect is removed to form cleaned area in the workpiece substrate. The cleaned area in the workpiece substrate is coated with a high-density coating. A sintering heat treatment is performed on the coated workpiece substrate to remove entrapped gas from the coating material prior to a step of hot isostatic pressing treating. Then, hot isostatic pressing treating is performed on the coated workpiece to produce diffusion bonding bewteen the workpiece substrate and the high-density coating. The material can be removed by techniques such as sandblasting or grinding. A high-density coating process such as hyper-velocity oxy-fuel thermal spray process or a detonation gun process is used to apply the high-density coating to the substrate at the location of the cleaned area. The high-density coating may have the same metal alloy composition as the metal alloy substrate. The metal alloy substrate may comprise a nickel or cobalt-based superalloy, and the high-density coating may have the same nickel or cobalt-based super alloy composition as the metal alloy substrate.

    Abstract: Disclosed are a method for assembling a polishing while inspecting for air leakage in the polishing head and an apparatus for performing the same. By the present invention, a polishing head may be tested for air leakage at each assembly step thereof, so that the polishing head may be assembled free of air leakage, thereby reducing testing time of the polishing head, and failure of the polishing head due to air leakage may be prevented. The apparatus includes a housing supporting the polishing head and having coupling lines coupled with ends of tubes provided in the assembled polishing head, or the polishing head being assembled. A pneumatic pressure regulating section selectively supplies positive pressure or vacuum to the tubes through the coupling lines. A sensor section detects the pressure and level of vacuum in the tubes. A determining section determines if there is air leakage in the polishing head.

    Abstract: The present invention relates to a method for repairing a turbine blade having a crack in a trailing edge portion of the blade. The method comprises the steps of cutting back a first surface of the turbine blade adjacent the blade trailing edge portion where the crack is located, and cutting back a second surface of the turbine blade adjacent the blade trailing edge portion where the crack is located. Each cut back step comprises cutting back the respective surface by a depth greater than the length of the crack and less than the trailing edge radius to remove the crack and form a cut back trailing edge portion. A compound radius is used to prevent a blunt transition into the trailing edge that would result in aerodynamic losses and to reduce the airfoil root stresses. The method also includes applying a thermal barrier coating to the turbine blade to increase service life. Prior to applying the coating, the tip portion of the turbine blade is modified to account for the change in the thermal characteristics of the turbine blade.

    Abstract: A modular submersible repairing system is capable of dealing with various tasks somewhat inefficiently, though, and of being inserted and installed in a reactor instantly, and highly maneuverable. A repairing method is carried out by the modular submersible repairing system. The modular submersible repairing system comprises a working unit including at least one type of tool module (1) capable of repairing structures in a reactor, a scanning/pitching module (2) capable of being selectively connected to or disconnected from the tool module, and provided with a scanning/pitching shaft for scanning or pitching the tool module, a submersible fan module (3) capable of being selectively connected to or disconnected from the scanning/pitching module, and a first buoyant module (4) for keeping the orientation of the tool module; and a base unit including a manipulator module (5) internally provided with an actuator driving mechanism, a adsorbing module (6) capable of being detachably mounted on the manipulator module and of adsorbing to a wall, and a second buoyant module (8) for keeping the orientation of the manipulator module. Each of at least the scanning/pitching module and the manipulator module is provided with a submersible connecting device (18, 21) capable of being operated in water for engagement and disengagement. The configuration and functions of the modular submersible repairing system can be changed or modified according to various purposes of work in the reactor by properly combining those modules. The modules can be connected together in the reactor by remotely operating the submersible connecting devices.

    Abstract: A method and apparatus is disclosed for expanding the ends of a sleeve that has previously been installed into a defective section of inaccessibly located soft metal heat exchanger tubing. The sleeve ends are expanded using an apparatus of a plastic bladder connected to a series of connectable sections of sufficient length to reach the ends of the installed sleeve. The expansion is performed by locating the plastic bladder inside the sleeve at one end and hydraulically compressing the plastic bladder and forcing it to expand in diameter as a function of Poisson's ratio to thus expand the sleeve end into the tube.
