Electroplating
Electroplating as a manufacturing capability for parts and components.
Electroplating parameters depend on the material, part geometry, required result and process limitations. Exact coating types and process conditions are agreed after the requirement is reviewed.

Electroplating
What Is Electroplating?
Electroplating is an electrochemical process in which a thin layer of one metal is deposited on the surface of another. The coating can protect the base material, change surface properties or provide the required appearance.
The process parameters depend on the base material, part geometry, intended result and technological limitations. Exact coating options are confirmed after the technical requirement has been reviewed.
Process principle
How Electrochemical Deposition Works
The part is placed in an electrolyte and connected as the cathode. The coating metal acts as the anode. When current is applied, metal ions move through the solution and form a layer on the prepared surface.
Layer thickness and structure are controlled through current, temperature, solution condition and processing time.
Benefits
Purpose and Benefits
Electroplating changes the surface properties of a part while retaining the characteristics of the base material.
- Protection of the metal surface from moisture and corrosion.
- Improved wear resistance for parts exposed to friction.
- A controlled decorative or technical surface finish.
- Longer service life under the intended operating conditions.
- Restoration of worn surfaces where the selected process permits it.
- Efficient use of a thin functional layer on a structural base material.
