NICKEL-BASE SUPERALLOY COATED WITH ALLOY CONSISTING OF IRIDIUM AND PLATINUM AND THEN DIFFUSION-METALLIZED WITH ALUMINUM

Title:

NICKEL-BASE SUPERALLOY COATED WITH ALLOY CONSISTING OF IRIDIUM AND PLATINUM AND THEN DIFFUSION-METALLIZED WITH ALUMINUM

Document Type and Number:

Japanese Patent JP3837559

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a coated nickel-base superalloy at a low cost which has superior mechanical strength, oxidation resistance and corrosion resistance at a high temperature, and is suitable for a jet engine, a gas turbine blade and a turbine vane, which are exposed to a high temperature and high stress.
SOLUTION: The nickel-base superalloy has an alloy coating consisting of iridium and platinum formed on its surface, and further has an aluminum layer diffusion-metallized on the alloy coating.
