Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite plating tank and a composite plating method for forming a composite plating film in which a composite material is dispersed on the entire surface of an object to be plated.

[0002]

2. Description of the Related Art When a composite plating solution in which a composite material is dispersed is collided to form a composite plating film on an object to be plated, it is important to disperse the composite material in the composite plating film and uniformly deposit the composite material. Then, the composite material is dispersed only in the portion that collides with the object to be plated. As a means for causing the composite material to collide with the object to be plated, conventionally, a method has been used in which the plating solution is stirred by air, rotated by a propeller, or circulated by a pump.

[0003]

In the conventional composite plating tank, the plating solution is collided with the object to be plated by stirring with air or propeller, circulating with a pump, or a combination of these means. However, since the flow of the plating solution becomes unidirectional and becomes turbulent, there is a problem that it is not possible to obtain a composite plating film in which the composite material is uniformly dispersed over the entire surface of the object to be plated.

An object of the present invention is to provide a composite plating tank and a composite plating method capable of obtaining a composite plating film in which a composite material is uniformly dispersed on the entire surface of an object to be plated.

[0005]

[Means for Solving the Problems] A composite plating tank is a composite plating tank in which a composite plating solution in which a composite material is dispersed is collided with an object to be plated to form a composite plating film on the object to be plated. At least one partitioning means for partitioning the bath, a rotating means for rotating the object to be plated, and a supply means for supplying the composite plating solution in a separate bath to the plating bath. In the composite plating method, the composite plating solution in which the composite material is dispersed is collided with the object to be plated to form a composite plating film on the object to be plated, and a plating tank and a separate tank are provided separately. Lower the liquid level of the composite plating solution in another tank through at least one partitioning means, form a constant flow of the composite plating solution flowing toward the other tank in the plating tank, and rotate the object to be plated. The composite plating solution is made to collide with the entire surface of the object.

[0006]

According to the present invention, the composite plating solution in the separate tank is fed to the plating tank by the feeding means to lower the liquid level in the separate tank, and the composite plating solution in the plating tank is divided into the partitioning means. Overflows and flows into another tank due to the drop in the liquid level. At this time, since the composite plating solution has a constant flow in the plating tank, the composite plating solution collides with the object to be plated with a constant flow, and the composite plating film in which the composite material is uniformly dispersed in the object to be plated. To form. Further, by rotating the object to be plated, the composite material collides with the entire surface of the object to be plated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the composite plating tank 1 is divided into a plating tank 3 and another tank 4 by a shielding plate 2 which is a partitioning means. A pipe 5 is connected to the bottom of the separate bath 4, and the pipe 5 extends to the bottom of the plating bath 3 beyond the peripheral wall of the plating bath 3. A large number of openings 6 are formed in the pipe 5 located at the bottom of the plating bath 3, and a pump 7 as a feeding means is provided in the middle of the pipe 5 outside the bath. Further, a motor 8 as a rotating means is provided above the plating tank 3, and an object 10 to be plated immersed in the plating tank 3 is rotatably supported by a rotating shaft 9 of the motor 8. There is. Next, a composite plating method using the composite plating tank configured as described above will be described. For example, the composite plating solution 13 in which the composite material 12 having a density of 1, 0 or more is dispersed in the chemical nickel plating solution 11 is put into the plating tank 3 and the separate tank 4. At this time, the liquid surface 14 in the plating tank 3 is set higher than the liquid surface 15 in the separate tank 4. Next, the pump 7 is driven to feed the composite plating solution 13 in the separate bath 4 into the plating bath 3 through the pipe 5.

Liquid level 1 of composite plating solution 13 in plating tank 3
4 becomes higher than the upper end of the shielding plate 2, the composite plating solution 13
Flows over the shielding plate 2 and flows into the separate tank 4. At this time, a constant flow 16 is generated in the composite plating solution 13 in the plating tank 3, and the composite material 12 collides with the composite material dispersion surface 17 of the object to be plated 10. Further, by rotating the object 10 to be plated by the motor 8, the composite material 12 collides with the entire surface of the object 10 to be plated. As a result of the powder, a composite plating film in which the composite material 12 is dispersed can be formed on the entire surface of the object to be plated 10.

In the above embodiments, the case where the plating solution is a chemical nickel plating solution has been described, but other plating solutions may be used. Further, the shield plate 2 and the separate tank may be plural.

[0011]

According to the present invention, the partitioning means divides the plating tank into a separate tank, forms a constant flow of the composite plating solution from the plating tank to the separate tank, and rotates the object to be plated. Because I chose. A composite plating film in which the composite material is dispersed can be formed on the entire surface of the object to be plated.
