Method for coating a high temperature resistant article with a thermal protection covering and high temperature resistant article

摘要

To coat the surface (12) of a component (13) which withstands high temperatures with a thermal protective layer, a cooling channel runs through the component with an opening (1) at the surface to be coated. During the coating operation, a mass flow (10) passes through the cooling channel opening of air or nitrogen gas or a noble gas or steam as the coating mass flow (11) is directed at the surface. The angle ( alpha ) between the coating and cooling mass flows is 0 degrees ≤ alpha ≤ 180 degrees .
