Current density 107/d,! 12, electrolytic lead plating is carried out by setting the electrolytic time and the plating amount corresponding to the electrolytic time as shown in Attached Table 1 to form a lead plating layer on the nickel plating layer. This second step does not necessarily have to be continuous with the first step, but from the viewpoint of ensuring the adhesion between both layers, it is desirable that the plating step be as continuous as possible. In addition, the lead-based plating layer is used to form a new surface at the interface during rolling joining with the lead plate in the next step (third step), but compared to the thickness of the underlying nickel-based plating layer, The required plating thickness is greater than 11 g/m2, preferably a plating amount of 10 g7'm2 or more.

) Rolling and joining was carried out using Ta-Ow. The rolling rate during rolling is downward,
The appropriate range varies depending on the rolling roll diameter, rolling speed, etc., but the important point is that new surfaces constantly appear at the interface during rolling, and a strong bond is created between the lead-based plating layer and the lead plate.

。In reality, the lead plate is a softer material than the titanium plate, so the titanium plate is hardly rolled, and although the appearance is good, sufficient adhesion is ensured under the condition that only the lead plate is rolled. Calculating from the change in the thickness of the previous lead plate and the thickness of the lead layer after composite, sufficient adhesion is guaranteed if the lead plate itself is rolled at a rolling rate of 30%, preferably over 50%. be.

Even if the content ratio is only a few percent, the crystals will be finer than that of a nickel-only plating layer, and a plating layer with a high cobalt ratio will have better adhesion. If the interfacial adhesion strength required for the product, the lead composite titanium plate, is extremely high, alloy plating is more advantageous than nickel-only plating.

What is the electrolysis time and the plating amount corresponding to the electrolysis time at a temperature of 25a and a current density of 10Am2? Electrolytic lead-tin alloy plating treatment is performed with the settings shown in Attached Table 1 to form a lead-tin alloy plating layer on the nickel-cobalt alloy plating layer. In the case of this lead-tin alloy plating layer, as the tin content increases, the adhesion to the substrate improves, and even if the content is only a few percent, the tin content in the lead-only plating layer improves. The plating layer with a high tin ratio has a stronger adhesion, especially when the rolling rate of the lead plate cannot be increased.

て複合される。As shown in the drawing, the lead composite titanium plate made in this way has a nickel-based plating layer 2 coated on the titanium plate 1 that removes the stable oxide film on the titanium plate and adheres to the base of the titanium plate 1. As a result, the upper lead-based plating layer 6 firmly adheres to the titanium plate 1 via the lower nickel-based plating layer 2 and is bonded to the lead composite layer 4 in an affinity manner. The titanium plate and lead plate are combined with sufficient adhesive strength.
