Definitions
- the invention relates to a device for surface treatment of a workpiece, according to the preamble of claim 1.
- a metallic coating is applied to a surface of a workpiece by means of a chemical or electrochemical reaction.
- the metallic coating is used to refine the surface of the workpiece, for example with regard to hardness, electrical conductivity, corrosion protection, catalytic properties, optical properties.
- the workpiece In electrochemical plating, the workpiece is placed in an electrolytic bath in which a consumable electrode consisting of the material required for the coating is immersed. By applying a DC voltage tion between the workpiece and the consumable electrode, the latter is removed and the coating is built up on the workpiece. The electric current dissolves metal ions from the consumable electrode and stores them by reduction on the workpiece. Thus, the object to be refined is uniformly coated on all sides. The longer the workpiece is in the bath, the thicker the coating becomes.
- the process of chemical electroplating basically proceeds identically, but uses the potential difference between the workpiece and the coating material typically dissolved in the bath, which is predetermined by the electronegativity of the chemical elements.
- the workpiece is subjected to a multitude of other preparatory and after-treatment surface treatments.
- the workpiece must be cleaned before coating, since the quality of the surface that can be produced by electroplating very much depends on the quality of the surface of the workpiece to be coated.
- the cleaning is done by degreasing and rinsing the surface of the still uncoated workpiece.
- the material of a workpiece to be coated by electroplating is all electrically conductive materials. Non-conductive materials must first be coated with a conductive layer, for example of a silver conductive ink. This process is also known as activation. After coating, the coated surface must first be cleaned of still adhering electrolyte, and then dried.
- galvanic systems consist of a very long series of tanks, in which the various surface treatments or process steps take place successively.
- the tanks are each equipped with a surface treatment required filled liquid.
- a workpiece must be transported from one tub to the other for each process step.
- the process results are not always satisfactory because the quality of the coating, for example, suffers from local heating during the application of the coating. Likewise, it can not be ensured with the known devices that the coating has a uniform thickness.
- the surface treatment is a galvanic metal deposition.
- the device comprises a container which is formed by a jacket which encloses a region which is complementary to a cross-section of the workpiece and is traversed by an electrolyte.

- the workpiece and container are not in direct contact, so that the inner dimensions of the container in the cross-sectional direction are slightly larger than the outer dimensions of the workpiece. In such a device, the workpiece must be transported adversely for each surface treatment required to produce a coating.
- US 5,277,785 discloses an apparatus for surface treatment of a metallic workpiece by electroplating.
- the device has a jacket which is complementary to a cross-section of the workpiece and accommodates a part of the workpiece to be subjected to a surface treatment and which can be filled with an electrolyte required as a medium for surface treatment.

- the mantle consists of two semi-cylindrical inner surfaces which simultaneously serve as electrodes.
- the workpiece forms the counter electrode. Two holders seal the room from the environment. At the same time you hold the workpiece in the room.
- the electrolyte in the room is continuously exchanged. This has the disadvantage that the workpiece has to be transported further for each individual surface treatment required to produce a coating.
- JP 60033383 A discloses a device for surface treatment of a workpiece.
- the device has a jacket which is complementary to a cross-section of the workpiece and accommodates the workpiece to be subjected to a surface treatment and which can be filled with an electrolyte.

Due to the uniform spacing, a uniform thickness of the coating during galvanizing is ensured in the device according to the invention. Due to the complementary shape and thus uniformly small distance between the shell and the workpiece, an acceleration of the coating process is also achieved.
