What are galvanic coatings, and what are their functions?

Galvanic coatings are metallic layers applied to a metal surface through electroplating processes . Their primary functions include: Corrosion protection – Preventing oxidation and degradation. Improved conductivity in case of silver coating – essential for electrical applications. Enhanced mechanical properties – Increasing metal hardness, wear resistance and durability Aesthetic and functional surface finishes – Improving the appearance and performance of components. In Electris, we specialize in technical coatings, primarily dedicated to the power industry

What are the most commonly used types of galvanic coatings?

The most widely used electroplated coatings include: Tin plating – Provides corrosion resistance and solderability. Nickel plating – Increases hardness, wear resistance, and oxidation protection. Silver plating – Ensures superior electrical and thermal conductivity. In our company copper plating process is not offered as a stand-alone service, but functions as a primer (subcoat) , used to improve the adhesion and quality of the final plating.

Which metals can be coated with galvanic layers?

At Electris Coating Systems , we specialize in electroplating copper and aluminum components . However, galvanic coatings can also be applied to steel, brass, and zinc , depending on industry requirements.

What are the benefits of galvanic coatings?

Extended component lifespan – Protection against environmental factors. Wear and abrasion resistance – Enhancing mechanical durability. Solderability and adhesion properties – Beneficial in electronic manufacturing. Stable conductivity – Ideal for energy and electrical applications. Custom thickness options – tailored coatings from 1 µm to 50 µm at Electris.

Do galvanic coatings protect against corrosion?

Yes. Electroplating creates a protective barrier that prevents exposure to moisture, chemicals, and oxidation. Coatings like nickel, tin, and silver enhance corrosion resistance significantly, particularly for components exposed to harsh environments.

What are the differences between zinc plating, nickel plating, chrome plating, and other methods?

Each type of coating has unique properties and applications: Nickel plating – boosts corrosion resistance, and improves both the strength and aesthetic appeal of the treated object. Tin plating – delivers contact efficiency, reduces friction, and offers corrosion protection in specific applications. Silver plating – this process yields an exceptionally durable coating, enhancing electrical and thermal conductivity at the coated surface while providing superior corrosion resistance.

How thick can a galvanic coating be?

At Electris , we offer coating thicknesses from 1 µm to 50 µm , depending on the application and performance requirements of the component.

Can galvanic coatings be used in the food industry?

Yes, certain coatings like nickel and tin plating are used in food processing equipment and packaging applications. However, coatings must meet food-grade safety regulations , depending on the intended use.

Are galvanic coatings environmentally friendly?

At Electris Coating Systems , we implement sustainable electroplating practices, including: Closed-loop wastewater treatment – Reducing environmental impact. Process heat recovery systems – Minimizing energy consumption. Additionaly we implemented EcoVadis certification , which confirms compliance with strict environmental standards.

cleaning and etching of metal before electroplating

Galvanic plating - metal purification and etching process

Cleaning and preparation is the basis of any electroplating process. Electris Coating Systems' high-tech electroplating plant offers the best pre-treatment solutions.

The bulk of the entire plating process is the component preparation process. It consists of several steps, such as cleaning, degreasing and etching, which must be done in the right order. This results in a surface that is conducive to better bonding with the new metal layer being applied to it. Proper preparation guarantees a durable coating of the highest quality and functionality.

Next steps in preparation for the electroplating process

Metal Purification

The first step is cleaning the surface of the metal. Any impurities, such as rust, dust or residues from previous treatments, are then removed. Cleaning is crucial because a clean metal surface promotes better adhesion of the plating layer. These treatments also remove oxides and other substances that can interfere with the application of the metal layer.

Metal Degreasing

Removing grease and oils from the metal surface ensures that no substances remain on the surface that could impede the adhesion of the plating layer. This step is critical to the quality of the bond between the metal coating and the substrate being electroplated.

Metal etching and decapping

The etching and decapping process is designed to remove the oxide layer of the metal from its surface. Removing these layers allows the metal of the substrate to come into direct contact with the plating layer, resulting in better adhesion.

After each of these processes, the component is thoroughly rinsed in dedicated process baths.

The Importance of busbar plating in Power Distribution Systems

Copper busbars play a critical role in modern electrical power transmission and distribution systems. To ensure long-term, reliable performance, proper surface protection is essential. This is where busbar plating becomes a key factor. Applying a high-quality metallic coating to busbars delivers substantial technical and economic benefits across a wide range of applications.

Key Benefits of Plating Copper Busbars:

Corrosion and Oxidation Protection - Copper busbars are constantly exposed to moisture, airborne contaminants, and fluctuating environmental conditions. A properly applied plating layer—such as tin, nickel, or silver—effectively shields the conductive surface from degradation, ensuring long-term durability and stable performance.
Reduced Heat Build-Up - busbar plating minimizes electrical resistance, significantly reducing energy losses in the form of heat. Lower thermal build-up helps maintain optimal system temperatures and extends the lifespan of components in high-current environments.
Stronger Joints and Electrical Connections - galvanic coatings enhance the mechanical and electrical integrity of joints and contact surfaces. This leads to improved connection stability, reduced voltage drop, and increased system reliability under demanding operational conditions.
Improved Conductivity and Electrical Efficiency - in the case of silver plating, for example, the superior conductivity of the coating material helps reduce power losses and boosts overall system efficiency—especially critical in high-power and high-frequency installations.
Lower Maintenance and Operating Costs - well-plated busbars require less frequent servicing and are less prone to wear, oxidation, or failure. Fewer breakdowns and longer service intervals translate directly into cost savings over time.
