Abstract
A method for coating articles, such as gas turbine blades, with a coating of variable thickness by securing a shield having one or more holes extending therethrough to the article thereby defining a shielded portion of the article, exposing the article and shield to a metal-bearing gas which is circulated around the article to deposit a metallic coating thereon, wherein the circulation of the gas adjacent the shielded portion of the article is restricted by the presence of the shield, thereby producing a substantially thinner coating on the shielded portion of the article than on the unshielded portion.
