Embodiment 1

[0016] Nickel plating on sintered NdFeB magnets to prevent corrosion of NdFeB magnets, the process conditions used are: NiSO 4 .7H 2 O 250 g / L, NiCl 2 .6H 2 O 50 g / L, H 3 BO 3 40 g / L, sodium lauryl sulfate 0.06 g / L, adjust the pH of the electroplating solution to 3.5, raise the temperature of the plating solution to 40°C, and the cathode current density is 1 ampere / square decimeter; start the ultrasonic generation before the electroplating starts Dispersed by means of an ultrasonic wave with an ultrasonic frequency of 25KHz and an ultrasonic power intensity of 0.5 watts / square centimeter, the microstructure of the obtained coating is as attached image 3 As shown in (1), using the same electroplating process, the microstructure of the coating obtained when the ultrasonic generator is not turned on is shown in the attached image 3 (2) shown. It can be seen from the figure that the coating layer is obviously much denser using the barrel plating equipment with ultrasonic w...

Embodiment 2

[0018] Copper plating on stainless steel with deep holes, the depth of the hole is 100mm, the diameter is 1mm, using ultrasonic barrel plating equipment, the electroplating solution is CuSO 4 ·5H 2 O 40 g / l; K 2 CO 3 80 g / L; HEDP 80 g / L; use KOH to adjust pH=9.5 temperature: 30°C, cathode current density: 1 ampere / square decimeter, anode-to-cathode area ratio greater than 2, start the ultrasonic generator before electroplating starts, The ultrasonic frequency is 30KHz, and the ultrasonic power intensity is 0.5 watts / square centimeter. After the electroplating is completed, it is found that the deep plating of the deep hole electroplating can reach 70mm. Turn off the ultrasonic generator, and conduct a comparative experiment under the same electroplating conditions. The result is that the coating depth obtained is only 20mm. . This shows that under the condition of using the ultrasonic generator, the coating performance of the inner wall of the deep hole can be greatly impro...

Abstract

The invention relates to a barrel plating device with the function of ultrasonic vibration, aiming at overcoming the defects that as plating solution is limited by a roller cavity when passing in and out a roller in the traditional barrel plating device, the plating layer effect of micropore and deep-hole parts is poor, and the like. The device mainly comprises a plating bath, an electrode, the roller, an ultrasonic generator and the like, wherein the ultrasonic generator is installed inside a fixed hollow shaft or a hollow electrode in the center of the roller, so that ultrasonic vibration can be effectively generated in the plating process, the dynamic balance of the plating solution is realized, and the deep plating effect and the compactness of a plating layer are improved.

Description

(1) Technical field [0001] The invention relates to a new barrel plating process and equipment, especially barrel plating for plated parts that are difficult to obtain a good coating. (2) Background technology [0002] As a kind of electroplating, barrel plating has been widely used. In rolling, single-barrel barrel plating machine is widely used. It is mainly composed of two parts: a barrel and an electroplating tank. The barrel is the container for the workpiece. At the same time, it is required to The liquid enters and exits freely. When working, the drum rotates in the electroplating tank, and the plating solution is exchanged with the electroplating solution in the electroplating tank by flowing in and out; The component and the conductive component provide rotation power to the drum and conduct working current. However, since the plating solution enters and exits the drum is restricted by the design of the holes on the drum, and the design of the voids, such as size a...
