A method and device which uses the technique of microarc oxidation (MAO) or plasma electrolytic oxidation (PEO) to create a thin ceramic conversion coating on metal sheets, foils or wires. The device comprises a mild steel metal tank 1 which is lined with fibre reinforced plastic (FRP) and contains an alkaline electrolytic solution, perforated nylon sheets 3, three bar nylon guides 4, three copper rods 5 which are supplied with power by high conductivity copper clamps 8 that are connected to a power system comprising thyristors 6 and transformers 7, a rotation drive 10, three collecting nylon rods 9, electrolyte inlet 11 and electrolyte outlet 12. The nylon bar guides 4, copper rods 5 and the collecting nylon rods 9 are rotated by the drive means 10. In use, the metal to be coated passes through the electrolytic solution along the copper rods 5 and the nylon bar guides 4 where a coat forms before being collected by the collecting nylon rods 9. |
