Abstract
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.
