Embodiment 1
[0038] A method utilizing cerium trichloride to refine electrodeposited nickel grains, the steps are as follows:
[0039] S1. Preparation of deposition solution: adding cerium trichloride to the electrolyte, stirring and dissolving to obtain a deposition solution;
[0040] S2. Cathode test piece treatment: stripping the polished surface of the cathode test piece, ultrasonic cleaning, rinsing, activating, rinsing, and drying to obtain the treated cathode test piece;
[0041] S3. Electrodeposition: adding the deposition solution to the electrodeposition tank, heating, putting in the cathode test piece and the anode test piece, connecting the power supply, electrifying and performing electrodeposition, and obtaining the cathode test piece after electrodeposition;
[0042] S4. Post-treatment of the cathode test piece: rinse, dry and seal the electrodeposited cathode test piece to obtain a nickel-plated cathode test piece.
[0043] In step S1, the electrolyte solution includes the...
