Abstract

PURPOSE:To aim at improvement of cooling effect by cutting grooves on the stock material of a turbine blade and closing the grooves with a covering member to form cooling passages. CONSTITUTION:A large number of grooves 2 are cut on the surface of the stock material 1 of a turbine blade. Next, a covering member 3 is joined on the surface of the stock material 1 of the turbine blade by the electrical casting to close the grooves 2. The shape of grooves 2 can be thereby set freely so that cooling passages having ideal cooling effect can be formed.
