How Does Electroplated Chrome Plating Work?
In galvanic chrome plating, chromium is deposited electrochemically onto a suitable electrically conductive surface.
The workpiece is connected as the cathode, while a suitable anode acts as the counter electrode. When electrical current is applied, chromium is deposited onto the workpiece surface from the electrolyte.
However, the chrome electrolyte is only one part of a successful plating process.
Surface preparation is equally important.
A professional chrome coating starts with:
Thorough cleaning
Degreasing
Removal of oxides and contamination
Suitable activation
Properly prepared surface
Correct current density
Suitable electrode positioning
Controlled plating time
The better the underlying surface is prepared, the better the final chrome finish can be.
Preparing a Surface for Chrome Plating
Before chrome plating, the workpiece must be thoroughly prepared.
Oil, grease, rust, oxides and other contaminants must be removed.
1. Clean the surface
Remove dirt, rust and existing surface contamination.
2. Degrease thoroughly
A completely degreased surface is essential for good adhesion.
3. Activate the surface
Depending on the base material, suitable activation is required before chrome plating.
4. Avoid re-contamination
After cleaning and activation, handle the workpiece only with clean gloves.
5. Polish the surface
For decorative chrome plating, the underlying surface should be as smooth and well prepared as possible.
Important: Chrome plating does not automatically eliminate scratches, dents or an uneven substrate. Surface defects can remain visible after plating.
Which Metals Can Be Chrome Plated?
The BMG-106 can be used for suitable conductive metal substrates.
Depending on the required pretreatment and plating system, applications include:
Nickel
Copper
Brass
Bronze
Steel
Stainless steel after suitable pretreatment
Silver
Gold
For high-quality decorative chrome plating, a suitable nickel intermediate layer is often used.
For unknown materials or alloys, always test the complete process on a suitable sample before processing valuable or production components.
Typical Chrome Plating Layer Structure
High-quality decorative chrome plating is often based on a multi-layer system:
Copper → Nickel → Chrome
Each layer can perform a different function.
Copper
A copper layer can be used to improve surface leveling and provide a suitable base for subsequent layers.
Nickel
Nickel provides an important intermediate layer and contributes significantly to corrosion protection, surface quality and the final appearance.
Chrome
The final chrome layer provides the characteristic bright, reflective chrome appearance and a hard, wear-resistant surface.
Therefore, professional chrome plating is not necessarily just “chrome directly onto the base metal”.
DIY Chrome Plating with Tank Electroplating
With tank electroplating, the complete workpiece is immersed in the chrome electrolyte.
This method is particularly suitable for:
Small and medium-sized components
Metal parts
Automotive parts
Motorcycle parts
Restoration components
Tools
Model-making components
Individual parts
Small production runs
The electrodes should be positioned appropriately for the geometry of the workpiece.
Uniform current distribution is important for achieving an even chrome coating.
Brush Plating and Tampon Chrome Plating
Not every component can be completely immersed in a plating tank.
This is where brush plating and tampon plating can be useful.
The chrome electrolyte is locally supplied to the area being coated while the chrome layer is electrochemically deposited.
This is particularly useful for:
Repairs
Partial surfaces
Large components
Difficult-to-access areas
Edges and details
Restoration work
Local replating
Individual components
This allows chrome to be applied electrochemically to areas where conventional tank plating is impractical.

Chrome coating becomes uneven
Possible causes include insufficient surface preparation, poor current distribution or unsuitable electrode positioning.
Chrome does not adhere properly
The most common causes include insufficient cleaning, degreasing or activation of the substrate.
Chrome is not sufficiently bright
The final appearance depends strongly on the underlying surface and the complete layer structure.
Key principle:
A chrome coating can enhance a properly prepared surface – it cannot replace proper surface preparation.
