    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.

    摘要: This invention relates to a component of an iron, cobalt or nickel-base alloy with a protective arrangement to prevent aluminizing or chromizing during gas diffusion coating, with a first layer as an interlayer and a second layer as a getter layer for reaction gases, where the first layer is a slip casting layer composed of oxide ceramic particles carried in a low-carbon vehicle free from halide, and the second layer is a metal layer or a metallic slip casting layer. The metal layer contains at least 50% by weight of the base-metal fraction of the component and exhibits all major alloy constituents of the component. The metal layer may be a sintered metal shape.

    摘要: A process for vapor depositing a metallic interlayer on the surface of a metal component, for example, by sputtering and thereafter depositing an aluminum diffusion coating on the interlayer. The metallic interlayer is vapor deposited on the surface of the component in a noble gas atmosphere, more than one-half of which, in per cent by weight, is composed of noble gases which are heavier than argon. Advantageously, the noble gases can be krypton or xenon. The process can be used with particular advantage for applying protective aluminum diffusion coatings on turbine blades.
