鉄箔が必要とされる。Electrolytic iron foil is obtained by electrodepositing iron on a peelable electroforming substrate such as titanium, stainless steel, or niobium using an electrolytic bath containing ferrous ions, and then peeling it off from the electroforming substrate. It will be done. Electrolytic iron foil is thinner, wider, and has better shape than steel sheets or foils produced by conventional rolling methods, and it also has higher strength, magnetism, and heat resistance than aluminum foil or copper foil. Because it can be used as a composite material with paper or plastic, or as an electrical material, it has many uses. Among these applications, composite materials require strength even if they are thinner, as well as toughness that can withstand light bending and drawing.
For electrical materials, electrolytic iron foil with even higher strength is desired. For example, building materials, packaging container materials, etc.
It is used by laminating it with plastic, but laminating requires improved strength of the electrolytic iron foil. In addition, as one of the uses of electrical materials, when electrolytic iron foil is perforated and used as a perforated shielding plate for color televisions, it is often used under high tension to prevent thermal distortion caused by electron beam irradiation. , or because the strength of the electrolytic iron foil allows it to maintain a specific shape, an electrolytic iron foil that has the strength to withstand these is required.

ついては、何らふれていない。In order to make electrolytic iron foil tougher, there is a strengthening method using alloys. Conventional iron alloy electrodeposition is, for example, disclosed in Japanese Patent Publication No. 44-258.
33', Japanese Patent Publication No. 54-12090, the purpose is to improve magnetism, corrosion resistance, and decorativeness, and electrodeposition is not intended. In other words, no consideration is given to manufacturing electrolytic foil by peeling off the plating layer.
-21227 describes a method for manufacturing iron base gold foil, but the alloying element content is as high as 40 to 50%, so it cannot be called electrolytic iron foil, and furthermore, there is no improvement in the mechanical properties of the resulting electrolytic foil. is not mentioned at all.

する方法などがある。In order to produce the above electrolytic iron foil, the concentration of ferrous ions in the electrolytic solution must be 150 to 4 CIOt/l.
If it is less than /l, the stress of the electrodeposited layer will be high and it will become brittle, and the electrolytic iron foil cannot be peeled off from the electroforming substrate. If it exceeds 400,971, the electrolytic voltage becomes extremely high, which unnecessarily increases power consumption, and crystals form as iron chloride, which is undesirable. The violet of N1 and Co ions in the electrolyte is 1 to 509
71 is preferable; if it is less than 12/l, the amount of Ni and Co eutectoid in the electrolytic iron foil is small and there is no toughening effect, and if it is more than 50 t/l, the amount of Ni and Co is too large. Eutectoid, increase electrodeposition stress, and use as electrolytic iron foil:
:X・1. :、、:、I can't be brave. Co content contained in the electrolytic iron foil is 0.5 to 20%, preferably 0.5 to 10961'#IJ, 20
A strip electrolytic iron foil containing 4 or more Ni and 0,000 or more suffers from significant distortion due to electrodeposition stress and cannot withstand use. Also N
Since i and Co have similar properties, they have the same effect on strengthening electrolytic iron foil, and when Ni and CO are used together, the sum of the amounts of each added is equal to the amount added when added alone. corresponds to To make Ni or Co ions coexist in the electrolyte, there are two methods: adding metal salts such as Ni or CO chlorides and sulfates, using these metals or alloys as part of the anode, or using an insoluble anode. There is a method of chemically dissolving these metals or alloys in a separate tank.

を悪曵するので好ましくはない。Further, the electrolysis temperature is preferably 95°C or higher; if it is lower than 95°C, the stress of electrodeposition is high, and even if electrodeposition is possible, it cannot be taken out as a foil. In addition, when the temperature exceeds 120℃,
This is not preferable because the electrolytic solution boils and entrains foreign matter into the electrolytic iron foil, resulting in poor surface conditions.

/d or less, a large amount of Ni or CO will precipitate,
Electrodeposition stress becomes high, cracks occur significantly, and the foil cannot be peeled off from the electroforming substrate. Furthermore, is it preferable to adjust the pH of the electrolyte to below O? , If the pH is 0 or more, the ductility of the electrolytic iron foil will be impaired.

-1096 can be contained, and a strong electrolytic iron foil with less distortion due to electrodeposition stress etc. can be obtained.
