KNOW-HOW

Surface treatment

Enhancing parts
for optimal
performance

Surface treatments are carefully selected to meet your product’s final requirements — to improve corrosion resistance, electrical conductivity, or simply enhance aesthetics.

Leveraging our expertise, we perform several treatments in-house, including mechanical processes like tribofinishing and chemical treatments such as pickling. For specialised functional coatings — like silver, nickel, or tin plating we partner with trusted experts renowned for their precision and quality. Every step is designed to ensure your parts are reliable, durable, and fully prepared for seamless integration.

Various surface
treatments

Explore the key benefits of copper and brass surface treatments, designed to enhance both
their technical performance and aesthetic appeal.

Chemical pickling

After hot forging, copper or brass parts often retain residues like lubricants or scale. Chemical pickling is used to clean the surface thoroughly, restoring its lustre and preparing the part for subsequent machining processes such as brazing or polishing.

tribofinishing

Tribofinishing is a mechanical surface treatment that removes remaining post-forging scale, smooths sharp edges, and evens out the surface texture. It enhances both the visual appearance and the functional quality of the part.

Electrochemical plating

Also known as electroplating, this process involves depositing a thin metal layer onto copper or brass parts using an electrolytic bath. This treatment enhances surface characteristics, improving properties such as electrical conductivity and corrosion resistance.

Key steps

The surface treatment of copper and brass at Forgeem involves a series of precise steps performed either in-house or in collaboration with trusted specialist subcontractors.

Surface preparation

Parts are thoroughly degreased to remove oils, grease, and residues left from forging and machining. This essential step ensures a clean surface, ready for treatment.

Acid pickling

Depending on the application, the parts undergo either mild or more intensive acid pickling. This process removes metal oxides and activates the surface chemically to promote optimal metal adhesion.

Electrolytic deposition

Once the acid action is neutralised, parts are immersed in an electrolytic bath to deposit a thin layer of metal —such as silver, nickel, or tin— depending on the required performance characteristics.

Rinsing and passivation

Thorough water rinsing follows to remove any remaining bath residues. A light passivation treatment may then be applied to stabilise the surface and protect the metal coating.

Fast drying

Immediate drying prevents the reformation of oxides or the appearance of stains. This final step ensures the optimal appearance and quality of the treated part.
