Effects of Electroplating

Electroplating has several effects on an object, including changes in conductivity, hardness, resistance, brittleness and luster.

When electroplating a metal surface, the component can gain favorable characteristics from the surface metal that is being plated onto the substrate. Electroplating often adds hardness and toughness to an object.

Solutions to Common Problems when Electroplating

Problem Solution
1. Sharp Edge:
Accentuated build-up of brittle chrome
Deburr and radius edge prior to plating.
2. Inside Corner:
Very thin chrome or lack of coverage
Radius the corner as generously as possible
3. Deep Narrow Grooves:
Brittle build-up of chrome on top edges and very thin or absence of chrome in bottom of groove
Radius top edges and bottom corners, open groove as far as possible, taper the groove
4. Scratches and Cracks:
Imperfections and reproduced in plating layer
Polish out surface imperfections prior to plating
5. Threads:
Pitch diameter is changed by chrome layer
Grind threads prior to plaring to allow for planned plating thickness, or mask threads to prevent plating
6. Inside Diameters:
Insufficient and non-uniform plating thickness through length of hole
Provide for plater to fabricate and position a plating anode inside hole to coat evenly and to proper thickness requirement, radius all corners to eliminate excessive build-up
