INTRODUCTION TO ELECTROPLATING FOR THE MEDICAL DEVICES INDUSTRY
There are two instrument that can be commonly used to perform electroplating, in the laboratory setting the potentiostat and at a larger scale a rectifier.
Using a potentiostat :
We control the current and the time and we observe the resulting potential
Using a current rectifier :
The ultimate aim of polishing and cleaning/activating is to make a water break free surface, as shown in the adjacent image. On the top half of the copper sheet, the surface isn’t completely clean and so the water is gathering up into droplets and staying on the surface of the metal. However, on the bottom half of the copper sheet the water has completely drained off the surface as it is completely clean and doesn’t provide anything for the water to cling to or gather around. This is a water break free surface and is ideal for effective electroplating. This should happen after you’ve completed the surface preparation step.
