Abstract
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 S), 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.
