Embodiment 1
[0025] A nickel-cobalt alloy electroplating process, comprising the steps:
[0026] (1) Degreasing and derusting: Put the workpiece to be electroplated into the drum, which is equipped with 1 / 2 volume of degreasing and derusting water bath. The degreasing and derusting water bath contains: Accelerator NS2.5g / L, diffusing agent DN1.5g / L, penetrating agent JFC2g / L, sawdust 4g / L, sodium polyacrylate 500001.2g / L, 69wt% nitric acid 20g / L, sodium lauryl sulfate 2g / L, sodium chloride 4g / L, rosin powder 2.5g / L, soak at room temperature for 25min, then wash at a speed of 60r / min for 30min to achieve the purpose of oil and rust removal;
[0027] (2) Ultrasonic cleaning: After degreasing and derusting, the workpiece is ultrasonically treated in an aqueous ethanol solution with an ultrasonic volume fraction of 20% at 40°C for 1-2min, and the ultrasonic frequency is 45Hz; after cleaning, re-inject clean water in the same ultrasonic Wash twice under low conditions, and finally blow dry; ...
