Method of manufacturing a component with a protective arrangement which prevents aluminizing or chromizing during gas diffusion coating |
摘要 |
A method for selectively protecting a component made of an iron-base alloy, cobalt-base alloy or nickel-base alloy with a protective arrangement which protects select areas of the component from aluminizing or chromizing during gas diffusion coating, wherein a first layer acts as an interlayer and a second layer acts as a getter layer for reaction gases. The method comprises the steps of depositing a first layer of slip cast material comprising oxide ceramic particles carried in a low-carbon, halide free, liquid vehicle; depositing a second layer comprising metal or a metallic slip, which comprises at least 50% by weight of the base metal of the component and all major alloy constituents of the component; aluminizing or chromizing by gas diffusion coating; and removing the protective arrangement from the component.
