### Electroplating: What Every Engineer Needs to Know

Because electroplating involves the use of current to initiate a reaction at the surface of a part, the overall geometry of the part will influence the current distribution, often called current density, across the surface of a part. Plating tends to build up on features such as sharp corners, bends or threads.
