Coating processes for corrosive environmental influences that is exposed to the iron-containing objects and coatings for the underwater body of steel boats

摘要

Coating processes for corrosive environmental influences that is exposed to the iron-containing objects with at least one zinc containing layer and an overlapping this coating, characterized by the following processing steps:1.1 a jet treatment for the exposure of the surface (16) of the object (11) to provide a cleaned and roughened surface structure,1.2 direct application of a rough, however, dense zinc layer (26) on this surface (16) having a melting - spraying process,1.3 Applying at least an adhesion-promoting, dense primer layer (28, 29) based on plastics, directly on the zinc layer (26) in a plurality of layers,1.4 Application of an intermediate layer (41) with adhesion-supporting characteristics to the primer layer (28, 29),1.5 Applying a conclusion coating (33).
