Abstract (en)

Process for pre-treatment of turbine blades (5) prior to spray coating in use by a streaming medium of the admitted blade region (8) in a spray coating unit. The blade base (6) is set in a hollow space (4) of a holding unit (1) so that it projects from the hollow space hole forming a gap between the hollow space perphery (3) and the turbine blade, where the gap is bridged over by screens (9-11) fixed to the holding unit. Each screen has a spray resistant synthetic plastic coating, especially in PTFE, placed so that it extends tro the boundary between the blade base (6) and blade region (8). Independent claims are included for:a turbine blade holding unit #a spray coating device.
