Abstract
A method for applying a thermal barrier coating to an article having cooling holes and concurrently cleaning obstructions, such as TBC overspray or other debris, from those holes is disclosed. A thermal barrier coating is applied to a first surface of an article having cooling holes. Concurrently therewith, a plurality of particles are projected against a second surface of the article, such that at least some of the particles pass through the cooling holes, strike the overspray constituents prior to cooling, knocking at least some of the obstructions out of the cooling hole.
