The iridium - platinum alloy canning nickel basic super alloy which features that aluminum having diffused and permeating in alloy coat

摘要

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.;COPYRIGHT: (C)2005,JPO&NCIPI
