Problems solved by technology

However, there is no better development of the device for preparing metal multilayer films by electrodeposition. Since the preparation of multilayer films requires different electrolytes, and different electrolytes require different current densities or different types of currents for electrodeposition, This difficult problem is not easy to solve, resulting in the traditional devices for preparing metal multilayer film coatings are mostly complicated in structure and not easy to operate.

Embodiment Construction

[0023] The present invention prepares the embodiment of the device of metal multilayer coating: as Figure 1-3 As shown, it includes a ring groove 1, a rotating mechanism, and two power sources 9. The device uses electrodeposition to prepare metal multilayer films. The two power sources 9 are used to provide currents of different sizes. Of course, different types of power sources can also be used according to actual needs. Current, such as direct current and pulse current. The material of the annular groove 1 is insulating materials such as glass and plastics, and four partitions 17 arranged at intervals in the circumferential direction are connected between the inner and outer groove walls of the annular groove 1, so that the annular groove 1 is divided into four fan-shaped grooves, The size of the two relative fan-shaped tanks is the same. When in use, different electrolytes are respectively filled in the two relative fan-shaped tanks. Distilled water is filled respectively...

Abstract

The invention discloses a device for manufacturing a plating layer of a metal multilayer film. The device comprises electrolytic baths arranged at intervals along the circumferential direction and power supplies for providing different current for an electrolyte in each electrolytic bath respectively, wherein metal pieces which are in conducting connection with positive electrodes of the respective power supplies extend into the electrolytic baths respectively in a suspended mode; a rotary mechanism comprises a rotating shaft of which the axis extends along the up-and-down direction and a power device for driving the rotating shaft to rotate; cantilever supports which extend along the radial direction of the rotating shaft are fixed to the rotating shaft; hanging frames are arranged on the cantilever supports; a current converter is arranged above the cantilever supports, and comprises fixed contact pieces which are arranged at intervals along the circumferential direction of the rotating shaft and are in one-to-one correspondence and conducting connection with negative electrodes of the power supplies and movable contact pieces which are in conducting connection with the workpieces; and the movable contact pieces are assembled on the side wall of the rotating shaft in an insulation mode and are in pivot friction fit with the fixed contact pieces sequentially. The integral device is simple in structure and convenient to operate, and the plating layer of the metal multilayer film can be manufactured only by hanging workpieces on the hanging frames.

Description

technical field [0001] The invention relates to a device for preparing a metal multilayer film coating by an electrodeposition method. Background technique [0002] Metal multilayer film, also known as composition modulation alloy, is a material in which the composition or structure of a metal or alloy is deposited on another metal or alloy and the composition or structure changes periodically. It is formed by the alternate growth of a variety of different materials. The mechanical properties of multilayer films change with the modulation wavelength. Multilayer films have many excellent properties, such as good electrical conductivity, corrosion resistance, wear resistance, decoration, magnetism, thermal stability, etc. [0003] The preparation and performance research of metal multilayer films has become a hot spot in the field of physics and materials science. The preparation methods include physical methods and electrochemical methods. The physical methods include vacuum...
