Abstract
A method for preparing a blade of a turbomachine for a spray coating process is provided. The method includes providing a sheet of flexible material which is shaped such that, when the sheet is bent circumferentially around a blade root of the blade along a longitudinal axis of the blade, the sheet forms a circumferential cover on the surface of the blade root, and bending the sheet around the blade root to form the cover. The sheet is positioned on the blade root up to a platform between an airfoil and the blade root. The sheet is placed on the blade root such that the sheet forms a circumferentially closed structure around the blade root. Further, an arrangement for a spray coating process is provided.
