種々試みられている。However, when stainless steel plates are used for the purposes mentioned above, if they are not maintained regularly, spots may occur.
Corrosion progresses. Unfortunately, this trend is becoming more pronounced as environmental pollution progresses and applications become more severe. For this reason, various attempts have been made to plate stainless steel plates to improve their corrosion resistance.

いう問題があった。(Problem to be solved by the invention) However, Zn--, which has excellent corrosion resistance, is used in stainless steel sheets.
When applying Ni alloys by electroplating, if the pretreatment is just general pretreatment such as degreasing and pickling, there is a problem that the adhesion of the plating is poor and it is not possible to produce plated steel sheets with good workability. .

できるようにした。(Means for Solving the Problems) The present invention provides Zn-old alloy plating with excellent adhesion by applying Fe-B alloy to a stainless steel plate by electroplating and then applying Zn-Ni alloy by electroplating. Made it possible to manufacture steel plates.
ステンレス鋼板は、表面が酸化皮膜に覆われているが、

少なくしてもめっ！＆密着性を改善できるという利点が
ある。The surface of stainless steel plate is covered with an oxide film,
This oxide film cannot be easily removed by degreasing or pickling, and good plating adhesion cannot be obtained even when electroplating a Zn-Ni alloy. However, after degreasing, pickling, etc.
For unknown reasons, when e-B alloy is pre-plated,
The oxide film is removed and activated, and the regeneration of a passive film such as an oxide film is prevented. In addition, this Fe-B alloy plating has better uniformity (coverage) than simple Fe plating, so even if the amount of plating deposited is small, the plating will still work! & It has the advantage of improving adhesion.

それ以上多くすることは経済的に不利となる。Figure 1 shows various types of F with different B contents on stainless steel plates.
After electroplating the e-B alloy, the Zn-Ni alloy was electroplated (coating amount: 30 g/J, one side), and the resulting plated steel sheet was subjected to bending process 2, and the plating adhesion was investigated. However, the B content is 0,001w
If it is less than L%, unplating occurs and the adhesion improvement effect of Zn-old alloy plating is small.
Although it does not affect the adhesion of Ni alloy plating, the effect of improving plating adhesion is almost saturated at 3 wt%, so
It would be economically disadvantageous to increase the amount more than that.

Using a plating bath consisting of ~509/e and using a stainless steel plate as a cathode, electroplating may be carried out at pl+2 or less and a bath temperature of 40 to 60°C.

The current efficiency decreases significantly, resulting in poor workability and p
When H becomes 2 or more, H+ ions decrease and Fe
Since the concentration of 3+ ions increases and hydrogen gas generation on the surface of the stainless steel sheet weakens, activation of the surface becomes insufficient and the adhesion of the Zn--Ni alloy plating decreases.

1l property was investigated, but the plating adhesion amount was 0.0
If it is less than 5 g/ω2, the adhesion of the Zn Ni alloy plating will deteriorate (the state of peeling of the plating layer was evaluated using the same criteria as in the case of FIG. 1).

However, when it becomes about 0.1 g/v' or more, the Zn-Ni alloy plating adhesion becomes almost constant. Therefore, if the coating weight is about 0.1 g/l12 or more, the adhesion will be almost constant, but from an economical point of view it is preferable that the upper limit is 10 g/m2 or less.

好になる。The electroplating of the Zn-Ni alloy after plating the Fe-B alloy can be carried out by a conventional known method and does not require any special conditions. However, the Ni content in the plating layer is
When the content is 5 to 25 wt%, corrosion resistance becomes good. In other words, Figure 4 shows the time required for red rust to occur by electroplating various Zn-Ni alloys with different Ni contents on a constant Fe-B alloy plating using a salt spray test. According to research, Zn Ni alloy plating has good corrosion resistance when the Ni content is 5 to 25 wt%.

特に限定しない。The Zn-Ni alloy plating adhesion improvement according to the present invention is effective up to a stainless steel plate with a Cr content of 30 wt%. Figure 5 shows this state, in which a stainless steel plate is electroplated with Fe-B alloy, and then ZnNi alloy is electroplated! Coating amount: 30 g/m2, one side)
The resulting plated steel sheet was subjected to a salt spray test (1000 hours) to investigate the occurrence of red rust. The higher the Cr content in steel, the better the corrosion resistance.
If it exceeds 0wt%, ZnN alloy! 1 adhesion is reduced, and the workability of the steel sheet itself is also reduced. On the other hand, the Cr content in steel is 5
If it is less than wt%, the edibility will decrease, so
It is preferable that the content be 5 wt% or more. Ni in steel
