Latest Patents
Kiyoshi Otake holds a patent for an "Alloy-coated gas turbine blade and manufacturing method thereof." This invention features a coated layer composed of a lower alloy-coated layer formed of an MCrAlY alloy, primarily consisting of cobalt or a combination of cobalt and nickel. The upper alloy-coated layer is made from an MCrAlY alloy whose principal element is nickel. The design includes a portion where the aluminum content is highest at the surface and decreases towards the interior. This configuration enhances the high-temperature anticorrosive properties of the gas turbine blade. The manufacturing process involves forming both coated layers and conducting an aluminum diffusion treatment into the upper layer. This innovative design aims to prevent high-temperature corrosion of the base material, thereby improving the reliability and extending the life of the gas turbine blade.
