られるという問題がある。In recent years, various methods have been introduced for electrolytically coating steel (S) IJ tubes with zinc-nickel alloys, but all of these involve coating on both sides. If coating only one side is desired and the steel strip is moved through an electrolyte containing zinc and nickel salts, the problem is that the nibkel will stick to the sheet metal on the uncoated side, interfering with further processing. .

により、上記の課題を解決した。An object of the present invention is to provide a method that does not have the above-mentioned drawback of adhesion on the uncoated surface. by applying a thin layer of the same material as that desired to be coated, then coating only one side with the material, and then electrolytically dissolving and removing said thin layer from the side opposite to that to be permanently coated. The above problem was solved by this method.

ing cell). This is done using a special electrolyte. Electrolytes based on aqueous sodium chloride solutions have been found to be particularly good in this regard. However, other soluble metal chlorides may also be used, for example potassium chloride, magnesium chloride. p
The h value is 7-12, i.e. p)! From a neutral solution of =7 p
Slightly alkaline solutions up to H=12 have been found to be particularly good. The reason is that dissolved metallic zinc and nickel readily precipitate as hydroxides in this pH range and do not stick on the steel strip. The hydroxides precipitated from these electrolytes can be removed from the solution by known methods such as precipitation and/or filtration and hydrocyclone or centrifugation.

側から溶解する。To melt the zinc-nickel alloy, a steel strip must be connected to the anode. Testing has shown that a connection method known in the industry as an inner (or center) conductor type is convenient for this purpose. Second
The figure shows a delaminated electrolytic cell so designed. As shown in the figure, at least one pair of electrodes (11), (12) to (1) are connected, one to the anode and the other to the cathode.

Furthermore, as the electrode material for the delaminated electrolyzer, both stainless steel and nickel or other known electrode materials can be used.Also, titanium sheets plated with platinum or iridium oxide can be used. Titanium sheets coated with metal can also be used as anodes.

流を供給した。There was a brown smear on the non-coated surface of the IJ tube, and chemically fixed nickel was detected on the non-coated surface using an electron scanning microscope. Therefore, according to the present invention, a thin layer removal electrolytic cell was added to this electrolytic coating apparatus, and the protective layer was electrolytically coated in the first electrolytic cell. An aqueous sodium sulfate solution was used as the electrolyte, and a dissolving current was supplied by a contact roller connected to the anode.

Only when the current was increased by a factor of 3 did the strips lose their adhesion, but a slight brown stain was visible on the surface after rinsing. Therefore, the electrolytic solution was adjusted to I=7 or replaced with an aqueous solution of phosphoric acid. In this case, the residual zinc-nickel on the surface disappeared only when a current three times the theoretical value was applied, but a slight brown smear was still visible, and an electron scanning microscope showed that phosphate crystals formed on a part of the surface. was identified. When passed through the delaminating electrolyzer according to the invention, the surface was metallically clean. and,
Only when treated with a sodium chloride electrolyte and an electrode arrangement with steel stout J tubes as internal conductors, contaminants such as residual zinc and nickel could not be detected even by electron scanning microscopy.
