【発明の名称】超合金基体上への白金-ケイ素-添加拡散アルミニド被膜の形成法

Document Type and Number:

Japanese Patent JPH0788564

Kind Code:

B2

Abstract:

A platinum-silicon powder is electrophoretically deposited on a nickel- or cobalt-base superalloy substrate (12). The deposited powder is heated to form a transient liquid phase on the substrate (12) and to initiate diffusion of Pt and Si into the substrate (12). An aluminium-chromium powder is then electrophoretically deposited on the Pt-Si enriched substrate and diffusion heat-treated to form a corrosion- and oxidation-resistant Pt-Si-enriched diffused aluminide coating (14) on the substrate (12). The presence of both Pt and Si in the aluminide coating (14) unexpectedly improves coating ductility as compared to a Pt-enriched diffused aluminide coating without Si on the same substrate material.
