    摘要： A brazing filler metal sheet is prepared. The brazing filler metal sheet includes a brazing filler metal layer, a sticking material layer, and a released paper. The brazing filler metal layer includes a brazing filler metal. A coating material layer is laminated on the brazing filler metal layer. The coating material layer includes a mixture of coating material particles and a binder. As the coating material particles, MCrAlY particles and abrasive particles are used. The coating material layer is then dried, and the brazing filler metal sheet is cut (step S4), and adhered to a rotor blade. The rotor blade is heated, to melt the brazing filler metal. The brazing filler metal diffuses due to the heat treatment holding process. A solidified layer is then formed by cooling. This solidified layer is subjected to blasting to allow the cubic boron nitride particles to protrude.

    摘要： The present invention provides an abrasion-resistant coating which has high oxidation resistance and durability and can be applied easily at a low cost. The abrasion-resistant coating in accordance with the present invention is formed at the tip end of a base material forming a gas turbine blade. The abrasion-resistant coating at the tip end has a thickness of 300 microns. On the tip end, hard particles H consisting of CBN are fixed in a bond coating formed by heating, melting, and solidification of a mixture of a brazing filler metal and M—Cr—Al—Y (M designates a metal element such as Co and Ni). The hard particles H are Ni and Co coated to improve wettability relative to the brazing filler metal, and are arranged so that some of them are partially protruded from the surface of bond coating to exhibit the grindability.

    摘要： The present invention provides a gas turbine in which a proper clearance is kept between a rotor blade and a shroud for a long period of time from the operation start, so that damage to the rotor blade is less liable to occur. In a turbine portion of the gas turbine in accordance with the present invention, the rotor blade and the shroud face each other. At the tip end of the rotor blade is formed an abrasive layer, and on the inner peripheral surface of the shroud is formed a heat insulating layer. The abrasive layer is formed of a matrix and many abrasive particles dispersed in the matrix. The abrasive particles include protruding particles protruding from the matrix and embedded particles embedded in the matrix. In initial sliding of the rotor blade and the shroud at the early stage of operation, the inner peripheral surface of the shroud is ground by the protruding particles. After the protruding particles have disappeared, the inner peripheral surface of the shroud is ground by the embedded particles.

    摘要： When a three-dimensional structure is formed by welding a plurality of members, accurate welding can be performed matching the three-dimensional shape. The teaching data consisting of the three-dimensional position at each of the welding points determined on each of the welding lines at a predetermined spacing on the basis of the design data of the three-dimensional structure is stored in a memory 18. A laser slit light sensor (a laser slit light emitting section 12 and a CD camera 13) is controlled by a total controller 17 via a camera controller 14 to photograph the welding point in order to obtain the image data of the welding point. An image processing apparatus 16 processes the image data to determine the amount of deviation from the design data of welding points. The total controller modify the teaching data on the basis of the amount of deviation from the design data of welding points to establish the modified teaching data and controls a welding head so that it moves according to the modified teaching data.

    摘要： A method and apparatus automatically repairs cracks produced in a member to be repaired. A wide field image is obtained by photographing the whole surface of a blade 31 or the like in a wide field view by a remote camera 11 and the position of cracks on the surface of the blade is obtained as a rough position information of the cracks by processing the image of wide field view. Then the cracks are photographed in a narrow field view at the predetermined spacing along the cracks based on the rough position information by a light section method. The narrow field images are processed to obtain the position, width, and depth of the crack at each predetermined spacing, which compose crack data at the series of points, and the cracks are repaired based on the crack data at the series of points.
