Method for electrochemical production of a metal strip, comprises guiding a rotating substrate by an electrochemical coating plant and electrochemically depositing a self-supporting layer on the substrate

摘要

The method comprises guiding a rotating substrate (11) by an electro chemical coating plant (17), electrochemically depositing a self-supporting layer on the substrate during guiding through the coating plant, and removing the self-supporting layer under obtaining a metal strip (22) from the substrate. The substrate is provided with a nickel oxide layer with a thickness of 10 nm before guiding into the coating plant. The nickel oxide layer is removed again from the substrate after the removal of the metal strip. The nickel oxide layer is produced with a thickness of 0.5 nm.

The substrate is provided with a nickel oxide layer with a thickness of 10 nm before guiding into the coating plant. The nickel oxide layer is removed again from the substrate after the removal of the metal strip. The nickel oxide layer is produced with a thickness of 0.5 nm. In the coating plant, electrolyte particles are dispersed that are deposited in the layer to be formed. Carbon nanotubes are used as particles. A brush plating is carried out in the coating plant. The nickel oxide layer is electrochemically produced through an anodic passivation. The substrate is coated with a nickel layer before producing the nickel oxide layer. The nickel layer is produced electrochemically as a bright nickel in a Watts-plating bath (15). The nickel oxide layer is removed from the substrate after stripping the metal strip in a decoating bath.
