Title:
タービン部品のアルミナイジングに用いられるマスカント
Document Type and Number:
Japanese Patent JP6480662
Kind Code:
B2
Abstract:
A mask is used in aluminizing of superalloy turbine component, such as a turbine blade, where a region exposed to relatively high operating temperature is aluminized to form a diffusion aluminide coating and another region exposed to relatively lower operating temperatures is masked to prevent aluminizing of the masked region while concurrently being enriched in Cr and/or retaining a pre-existing Cr-content from the superalloy chemistry itself or from a previous chromizing operation.
