Method for coating, pole tube and device for executing the method

摘要

The method involves forming a corrosion protection layer on a workpiece. A metallic bonding layer is applied electrolytically on boundary surface of workpiece, before formation of corrosion protection layer. The metallic bonding layer is made of electrolytic nickel strike. The corrosion protection layer is made of zinc material. Independent claims are included for the following: (1) pipe pile; (2) apparatus for coating two different metallic materials on surface regions of workpiece; and (3) clamping leg.
