Device for manufacturing plating layer of metal multilayer film

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 using an electrodeposition method. Background technique [0002] Metal multilayer film can also be called composition modulation alloy. It is a material with periodic changes in composition or structure formed by depositing a metal or alloy on another metal or alloy. It is formed by the alternating growth of multiple different materials. The mechanical properties of multilayer films change with the modulation wavelength. Multilayer films have many excellent characteristics, such as good electrical conductivity, corrosion resistance, abrasion 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. Among them, physical methods include physical vapor deposit...

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.
