Summary: | The invention relates to a new energy automobile battery integrated part insert electroplating process, and belongs to the technical field of automobile parts. An insert is subjected to specific pre-treatment, then electroplating conditions are adopted, electroplating liquid is prepared from 260-300 g/L of nickel sulfate, 34-45 g/L of nickel chloride, 40-50 g/L of boric acid, 8-10 ml/L of a cylinder opening agent, 0.1-0.2 ml/L of a brightening agent and the balance deionized water, the pH of the electroplating liquid is adjusted to be 4-5, the temperature is 50-60 DEG C, and the insert servesas a cathode, the introduced current density is controlled to be 15-30 A/dm , the reaction time is 10-40 min, the insert is electroplated, finally, a plating layer is subjected to activation and hotwater cleaning, the obtained insert product is excellent in corrosion resistance, no white rust spot exists in 72 h of a 35 DEG C 50 g/L NaCl neutral salt spray test, and the stripping area of the edge of a hundred-grid test no |
