摘要:
This invention relates to processes for the formation of composite layers containing insoluble particles in metal matrices onto bodies to achieve enhanced thermal properties.
摘要:
A roughened bond coat comprises a screen that includes interwoven wires defining openings and a metallic material disposed on the screen. The screen and metallic material form a roughened bond coat possessing an uneven, undulated, and irregular surface. The metallic material may be one of a slurry and a powder, and applied by coating and spraying, respectively. A thermal barrier coating system, which is formed with and incorporates the roughened bond coat, exhibits greater adhesion of a thermal barrier coating and bond coat due to an increased interfacial surface area provided by the uneven, undulated, and irregular surface.
