    摘要: A turbulator fabrication process (100) and a fabricated article are provided. The turbulator fabrication process includes providing a system (200) configured for directing a first fusion energy (201) and a second fusion energy (202), positioning a turbulator material (205) on a substrate (207), and directing the first fusion energy (201) and the second fusion energy (202) toward the turbulator material (205) and the substrate (207). The directing of the first fusion energy (201) and the second fusion energy (202) modifies the turbulator material (205) forming one or more turbulators (210) on the substrate (207). The fabricated article includes a substrate (207) and one or more turbulators (210) formed on the substrate (207). Each of the one or more turbulators (210) includes at least one root portion providing a concave transition between the substrate (207) and the turbulator (210).

    摘要: A method is provided for high velocity air plasma spraying (APS) application of a protective coating system, such as a bond coat with or without an overlying ceramic thermal barrier coat, to a superalloy metal substrate. Application of MCrAlY alloy bond particles (where M is at least one of iron, cobalt, or nickel) onto the metal substrate is maintained at a particle velocity of at least 400 meters per second (m/s), for example within a range of 400 m/s to 700 m/s. The resulting bond coat on the metal substrate has a surface roughness of about 300 to about 500 µinch Ra, and a density of at least 90% of theoretical density. The protective coating may include a ceramic thermal barrier coat applied over the bond coat by any suitable process.
