Abstract
A method and apparatus form a thermal barrier coating on a metal component. A molten thermal barrier coating powder is sprayed on the component in sweeping strokes. A plurality of overlapping solidified coating ribbons are deposited on the component and include a sequentially deposited surface ribbon forming sublayer ribbons therebelow. The surface ribbon is preheated at a spray site so that the sprayed molten powder remelts the surface ribbon at the spray site for sequentially welding the sequentially deposited surface ribbons to the sublayer ribbons.
