A process of electroplating a continuous metal material in a longitudinal array (in several electrolytic cells) through which a single electrolytic solution continues to flow. is injected into the bottom of each electrolytic cell, contacting both sides of the continuous material. This process primarily electroplates copper, tin or zinc strips or wires. There is no suggestion that this process would be used to electrodeposit alloys.The composition of an alloy electrodeposited from a paddle of a given composition and at a given temperature depends on the current density at the cathode. It is known that the current density mentioned above is specified so that the composition of the oak remains constant without the need for continuous correction by the addition of chemicals in which the anode is being used. It is also known that the anode supplies the metal needed to replace the metal already deposited to the bath during the deposition of the zero alloy.
An anode consisting of the alloy to be deposited, which is multi-dimensional and therefore not easily controllable, or an anode consisting of a pure metal of the base metals, which are immersed in cypress and alloyed. It is common to use The first mentioned example creates difficulties in preparing the alloy and dissolving it uniformly in the bath, and only alloys with a given composition are formed. On the other hand, in the second mentioned example, it is difficult to melt several seven nodes at the rate at which the respective metals are added to the electrolyte, and between anodes immersed side by side made of different materials. There is a problem with the interaction etc.

保持されるように選ばれる。It has been found that the above-mentioned difficulties can be eliminated by a process that is extremely simple and reliable. In the first mentioned process, only an anode consisting of pure, unalloyed material is immersed in each electrolytic cell. Limitations regarding electrolytes,
The electrolytic cells are effectively separated from each other, and these electrolytic cells are not tied together! Being connected or connected to the line and the pulp exhibiting a high resistance to electrolyte flow, the anode can dissolve at a controlled rate within the associated electrolytic cell. This ratio is chosen to obtain and retain the desired concentration of each metal ion.

大され、またその反対ともなる。This is preferably obtained as follows: the anode surface area of each alloying element in contact with the electrolyte is selected accordingly. That is, the aforementioned surface area of each anode formed by a given alloying element in contact with the electrolyte is adjusted as required. In other words, when the concentration is to be increased, the surface area is increased and vice versa.

This is because it depends on a certain current density at the cathode. Therefore, by appropriate means of adjusting the operating delta parameters, laboratory tests were carried out to determine the composition of the cypress, the current density in the heat sink and the temperature of the cypress, thus: Obtain the desired precipitation. The model or production equipment is then operated at the desired current density at the cathode and the immersed anode surface area of each anode metal is increased or decreased to increase or decrease the immersion of the metal under the operating ferrous nature. Maintain desired concentration. The anode surface area of a given metal is
Can be changed. Then either the non-metal anode described above is removed from the cypress, or an additional anode made of the metal described above is immersed in the bath.
