A method for producing a galvanically deposited protection layer against hot gas corrosion of a structural component, involves immersing the structural component in an electrolytic bath of a cobalt and/or nickel matrix material. Alloying chromium and/or aluminum particles are suspended in the electrolytic bath. Gas bubbles are mixed into the electrolytic bath, and the immersed structural component is rotated in the bath while the galvanic deposition or coating takes place. The bath is stationary and rotation of the structural component takes place about a substantially horizontal axis.

Galvanically or electrolytically deposited protective coatings are produced on structural components such as gas turbine blades by suspending in the electrolytic solution a metal alloy powder of which the particles have a spherical configuration and a passivated surface. The concentration of the particles in the electrolyte is preferably smaller than 100 g/l, whereby a high insertion rate of up to 45% by volume has been achieved at relatively low costs and small technical efforts.
