Abstract

The invention discloses an electrochemical testing device provided with array electrodes, a reference electrode and a circulation system, which relates to an electrochemical testing device. The electrochemical testing device aims at solving the problems that the traditional electrolytic cell used in labs does not have an appropriate space for placing an array electrode and a reference electrode to imitate selective plating of small parts, and cannot be used for carrying out electrochemical test in a plating solution circulating state so that the testing result and the actual production condition have larger difference, and the production cannot be effectively instructed. A reference electrode slot of the electrochemical testing device is arranged on a pipe opening in a penetrating way, the reference electrode is inserted in the reference electrode slot, an electrode slot is arranged in a sealing cover, a group of array electrodes are inserted in a cathode test piece placing hole, the lower end of a plating bath body is arranged in an anode bottom tank body, an anode wiring column is arranged on the anode bottom tank body, an anode plate is positioned in the anode bottom tank body and supported by an anode supporting frame, an adjusting tank cover is buckled on the adjusting tank, and an opening on the adjusting tank cover is used for plugging an electric plating detector. The electrochemical testing device is applicable to an electrochemical testing process.

Description

technical field [0001] The invention relates to an electrochemical test device, in particular to an electrochemical test device with an array electrode, a reference electrode and a circulation system, and belongs to the technical field of metal surface treatment. Background technique [0002] With the development of environmentally friendly electrodeposition technology for rare and precious metals and the use of new electrolytes such as ionic liquids, the plating solution needs to be circulated and filtered to maintain a stable working state. However, the electrolytic cell used in the existing laboratory does not have a suitable space to place array electrodes and reference electrodes to simulate the partial electroplating of tiny parts, nor can electrochemical tests be carried out under the condition of plating solution circulation, so the measurement results are different from the actual production conditions. Larger, cannot effectively guide production. Contents of the ...
