摘要：
Method for applying a corrosion-protection layer to the base body (1) of a gas turbine blade by embedding particles (3) of SiC in a metallic matrix by means of powder, paste or electrolytic/electrophoretic methods and compacting, welding or fusing and bonding the matrix-forming material to the base body (1) by means of hot-pressing, hot isostatic pressing or laser beam, electron beam or electric arc. Protective layers are formed which do not flake off and with high silicon content which is at least partially contained in the embedded, partly modified SiC particles (6) as a reservoir for the operation.
