FAQs

Get answers to frequently asked questions about electroplating and learn more about Tónus Kft's expertise in this field.

What is electroplating?

Electroplating is an electrochemical process in which metals are coated using electrical currents. It is based on the principle of electrochemistry, in which chemical reactions are stimulated by electrical energy. The main components are an electrolyte solution, an anode (the coating material) and a cathode (the object to be coated). A power source provides the necessary voltage to enable the material to be transported.

This process is used to protect metals against corrosion, improve their adhesion or achieve a decorative finish. The chemical processes include the dissolution of metal ions at the anode and their deposition at the cathode.

What processes and techniques are used for electroplating?

There are various electroplating techniques that vary depending on the application. The most important processes include:

  • Electroplating: Protection against rust.
  • Nickel plating: Increasing wear resistance.
  • Hard chrome plating: For mechanically stressed surfaces.

According to the Federal Institute for Materials Research and Testing (BAM), 2022. there is a significant difference between electrolytic deposition, in which an electric current is used, and electroless plating, which is based on chemical reactions. Modern alternatives such as powder coating or anodizing offer additional options for specific applications.

What preparation techniques are used before electroplating?

The quality of the electroplated coating depends largely on the preparation of the surface. The most important steps include:

  • Mechanical grinding and polishing: Unevenness is removed.
  • Chemical cleaning and degreasing: Impurities are removed.
  • Adhesion tests: Ensuring that the coating adheres optimally.

What materials and chemicals are used for electroplating?

Metals such as zinc, nickel, chrome and gold are used for electroplating. Their selection depends on the desired properties, such as corrosion protection or conductivity.

Electrolytes containing metal salts and additives play a central role in the process. However, handling chemicals such as cyanide solutions requires special precautions as they are harmful to health. According to Schlesinger, M. & Paunovic, M. Modern Electroplating, more environmentally friendly alternatives such as sulphate-based electrolytes are increasingly being explored. Wiley, 2010. increasingly being researched.

What are the advantages of electroplating?

Electroplating extends the service life of metal products by creating a robust protective layer. It makes the material more resistant to corrosion and at the same time ensures a visually appealing, uniform surface finish.

How does electroplating work in metal technology?

We only carry out suspended surface treatments in our plant. This process ensures a uniform and high-quality coating.

The process begins with a thorough pre-treatment. Chemical and electrochemical degreasing removes oily residues and other impurities from the surface. The surface is then activated to make it metal-free and surface-active. This creates the ideal basis for a high-quality metal coating.

A zinc anode serves as the material source for the coating process, while the surface to be coated acts as the cathode. The cathode is immersed in a zinc bath, which is equipped with a vertical cathode movement. This movement ensures an even coating of the workpiece.

The electrolysis process is started by using direct current. This forms a corrosion-resistant metallic coating on the steel part. The coating thickness varies between 8 and 20 µm, depending on the customer's specific requirements.

After coating, the surface is treated with corrosion-resistant passivation solutions. Depending on the customer's requirements, we use blue or yellow passivations, which provide additional protection and a high-quality appearance.

Nach der Oberflächenbehandlung benötigen die Werkstücke keinen weiteren Oberflächenschutz, können aber auf Wunsch lackiert werden, was auch im Haus möglich ist.

Which materials can be electroplated?

We galvanize workpieces made of steel, wrought iron, cast iron and copper.

What different manufacturing processes does Tónus Kft. offer in electroplating?

Tónus Kft. carries out surface treatment in two production lines, which allow different maximum workpiece dimensions and post-treatment options:

  • Line I
    Maximum workpiece size: 2000 x 850 x 450 mm
    Post-treatment: blue or yellow passivation
  • Line II
    Maximum workpiece size: 2800 x 1100 x 550 mm
    Post-treatment: Blue passivation

This configuration enables precise and high-quality processing of workpieces in various sizes.

How much does it cost to electroplate metals?

The cost of electroplating depends on the specific requirements of the end product, such as the desired coating thickness, workpiece dimensions and post-treatment. Our team will be happy to provide you with an individual quote that is tailored precisely to your needs.

What impact does electroplating have on the environment?

The technology used is modern, environmentally friendly and meets today's needs and requirements.

  • Recycling metal waste: Reducing material consumption
  • Emission control: modern filter technologies minimize harmful emissions

We operate under a comprehensive environmental permit and use the best available techniques for the surface treatment of metals.

The technology used is modern, environmentally friendly and meets today's needs and requirements.

The passivation is Cr(VI)-free.

What layer thickness is achieved during electroplating?

During electroplating, a coating with a thickness of up to 20 µm can be applied. The exact thickness is adapted to the customer's requirements.

In which industries is electroplating of products used particularly frequently?

  • Construction and building materials industry
  • Automotive industry
  • Electronics industry
  • Jewelry industry
  • Household appliance industry
  • Aerospace industry
  • Packaging industry
  • Heavy industry
  • Medical equipment industry

Special processes even make it possible to coat plastics, which is relevant in the automotive and household appliance industries.

How does quality assurance take place during electroplating?

In order to be able to offer our customers the highest possible product quality, we continuously implement quality assurance measures. These measures include:

  • Inspection of finished products
  • Coating thickness measurements (ensures uniform coatings)
  • Surface inspection (identifies defects such as cracks or pores)
  • Long-term tests (check durability under real conditions)
  • Porosity tests
  • Salt spray test
  • Chemical composition testing
  • Electrical tests (if required)
  • Documentation and records
  • Accurate process controls
  • Ongoing training and qualification of our personnel
  • Error analyses
