Method and device for the partial galvanization of surfaces which are conducting or have been made conducting

A device for the partial galvanization of a surface of a material which is or has been made conducting, comprising:

• an electrolyte solution for use in depositing a metal or its alloy on the surface to be galvanized;
• a flow-on channel and a flow-off channel positioned at an angle relative to the surface of less than 45.degree. and arranged to direct the electrolyte solution at an angle onto the surface to be treated where it is removed at an angle to the surface by the flow-off channel such that on the surface to be treated a substantially laminar flow arises;
• the flow-on channel and flow-off channel each being constructed of a corrosion-resistant material;
• and a metallic anode element arranged in at least one of the flow-on and flow-off channels.

A device for the partial galvanization of a surface of a conductive material, comprising:

• means for supplying an electrolyte solution for use in depositing a metal or its alloy on the surface to be galvanized;
• a flow-on channel connected to said means for supplying and a flow-off channel positioned at an angle relative to the surface to be treated of less than 45.degree., the two channels being positioned to direct the electrolyte solution onto the surface to be treated such that a substantially laminar flow arises across the surface from the flow-on channel to the flow-off channel;
• the flow-on channel and the flow-off channel each being constructed of a corrosion-resistant material;
• and a metallic anode element arranged in each of the flow-on and flow-off channels directly adjacent to the area at which the surface to be treated is to be located, each of said anode elements having a tunnel-like shape through which the electrolyte solution flows.
