Die Diversity of Surface Treatments at Febrotec

At Febrotec, the focus is on the quality and durability of components. A key factor in achieving this is the selection of the right surface treatment. Below, we provide an overview of the various processes we offer: zinc coating, shot peening/glass bead blasting, passivation, varnishing, and chroming. Each method has its own strengths and specific fields of application — and at Febrotec, we ensure your components receive the optimal treatment.

Heat Treatment / Tempering

The thermal post-treatment of springs serves to reduce residual stresses generated during manufacturing and increases the tensile strength of the material by stabilizing its internal structure. 

Zinc Coating – Corrosion Protection through Zinc

Zinc coating is a proven method for effectively protecting steel components against corrosion. A layer of zinc is applied to the material, acting as a sacrificial anode. This layer prevents moisture from penetrating and significantly extends the service life of your components. Zinc-coated surfaces are especially suitable for use in harsh environments, such as construction and the automotive industry.

Shot Peening and Glass Bead Blasting - Perfect Surface Preparation

Shot peening and glass bead blasting are mechanical surface treatment methods. These processes remove surface irregularities, smooth the surface, and create an ideal base for subsequent coatings. While shot peening is typically used for coarser surface textures, glass bead blasting is a gentler method especially suited for sensitive materials.

Passivation – Additional Protection for Metal Surfaces

Passivation is a chemical process in which a protective oxide layer is formed on metal surfaces. It is particularly used on stainless steel to improve corrosion resistance. Passivation not only enhances protection but also provides a uniform and aesthetically pleasing surface appearance.

Varnishing – Versatile Design Possibilities

Varnishing focuses not only on protection but also on aesthetics. With a wide range of colors and finishes available, components can be customized to suit various design needs. Paint provides protection from environmental factors such as moisture, UV radiation, and mechanical wear. Whether functional or decorative – painting offers nearly limitless possibilities.

Chroming – Glossy Protection and Elegant Design

Chroming combines functionality with elegance. A layer of chrome offers excellent protection against corrosion and wear while giving the component a high-gloss, premium look. This process is widely used in the automotive and furniture industries, where both durability and visual appeal are important.

Electropolishing Stainless Steel - Benefits & Applications

Electropolishing is an electrochemical process used to refine stainless steel. The component is submerged in an electrolyte bath, resulting in a smooth, corrosion-resistant, and hygienic surface. This treatment strengthens the metal's passive layer and enhances its resistance to corrosion. At the same time, it creates an ultra-smooth surface that is easy to clean and prevents buildup. The process also reduces friction, making it ideal for use in medical technology and piping systems. Additionally, electropolishing gives the material a brilliant, mirror-like shine and removes microcracks, improving material integrity.
