The overview below shows the thermal and surface treatments that we provide as standard to our partners. If necessary, we will also provide the necessary documentation. If the method you require is not listed, please contact our managers – we may still be able to help you.
Fe alloys
Blackening
Black finish or blackening is a conversion coating applied to metallic materials. It is used to add corrosion resistance and minimize light reflection.
Blackening
Phosphating
The surface of the material after the phosphating process is porous and suitable as a conversion layer for subsequent painting or coating.
Phosphating
Nitriding
Nitriding is a surface hardening process in which nitrogen atoms combine with the surface of a metal alloy.
Nitriding
Tenifer/short-time nitriding
A series of patented hardening processes that diffuse nitrogen and carbon into metals at special temperatures during a salt bath.
Tenifer/short-time nitriding
TiN coating
Titanium nitride is an extremely hard ceramic material that is often used as a coating on titanium alloys (and other alloys) to improve the surface properties of the material.

Pickling and passivation
Passivation is the controlled formation of a protective layer on a metal surface, preventing corrosion and surface damage. This is achieved by the action of chemicals or electrochemical methods without changing the colors.
Pickling and passivation
Sandblasting
The process of manipulating very small pieces of material at high speed into a surface for the purpose of cleaning or etching a (metal) surface.
Sandblasting
Polishing
Metal polishing is a finishing method that uses an abrasive material to smooth surfaces. After polishing, the surfaces of metal objects are free from defects and become more reflective and shiny

Chemical and galvanic nickel plating
Protection in the form of a galvanic coating protects the parts against corrosion. It also significantly improves the appearance of the final product.

Al alloys
Natural anodizing
A smooth and uncolored film that is transparent and shows the appearance of the underlying metal.
Natural anodizing
Colored anodizing (red, black, blue, green)
Anodizing is an electrochemical process that converts a metal surface into a decorative, durable, and corrosion-resistant finish – in a variety of colors.
Colored anodizing (red, black, blue, green)
Hard anodizing
Higher quality and thicker corrosion protection layer, increased wear resistance and reduced friction resistance.
Hard anodizing
Heat treatment
Oil and vacuum quenching
A hardening process, the purpose of which is to transform the material into an austenitic and resistant structure.
Oil and vacuum quenching
Cementing
Carburizing is a widely used surface hardening process that increases wear resistance.
Cementing
Tempering
A heat treatment used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening to reduce some of the excess hardness.
Tempering
Annealing
A heat treatment process used mostly to increase ductility and reduce hardness of a material.
