Surface Finish and Heat Treatment

Surface Finish and Heat Treatment

In the below overview you can find the heat and surface treatments which we provide standard for our partners. Obviously when needed we bring forth requested documentation. When your desired treatment is not mentioned, please contact our account managers, maybe it is possible to assist you anyway.

Fe alloys

Black finish

Black finish or blackening is a conversion coating for ferrous materials. It is used to add mild corrosion resistance and to minimize light reflection.

Phosphating

The layers of material after chemical process are porous, absorbent and suitable as a conversion layer for subsequent powder coating without further treatment.

Nitration

Nitriding is a surface hardening process where atomic nitrogen is introduced into the surface of a ferrous alloy.

Tenifer/short-term nitration

This is a range of proprietary case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures during a salt bath

TiN coating

Titanium nitride is an extremely hard ceramic material, often used as a coating on titanium alloys (and other metal components) to improve the material’s surface properties.

Staining and passivation

Passivation is a controlled formation of a protective layer on a metal surface, preventing corrosion and damage to the metal surface. It is achieved by the action of chemicals or electrochemical methods without color changes.

Blasting with glass beads

Process of propelling very small pieces of material at a high speed in order to clean or etch a (metal) surface.

Polishing

Metal polishing is a finishing method that uses an abrasive material to smooth surfaces. When polished, the surfaces of metallic objects are freed of defects and become more reflective and shiny

Coating according to the customer’s specifications

We can adjust our modifications to the requirements of our customers – just let us know your demands.

Chemical and galvanic nickel finish

To protect parts against corrosion, there is the protection in form of galvanic coating. It also greatly improves the fnal product’s appearance.

Passivation and white zinc finish

White Zinc’s unique protection combines superior rust inhibiting properties of zinc with a tough but flexible enamel coating and elegant color.

Al alloys

Natural anodising

Smooth and uncoloured anodic film which is transparent and shows the appearance of the underlying metal.

Colour anodising (red, black, blue, green)

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant and anodic oxide finished part.

Hard anodising

Higher quality and more coarser protection layer against corrosion, increased wear resistance and reduced frictional resistance.

Heat treatment

Oil, vacuum and induction quenching

Hardening process which purpose is to transform a material into an austenitic martensitic structure.

Cementing and quenching

A cemented quenching heat treatment method is a step of carrying out cemented quenching treatment on the forged, pre-heated, machined and hobbed gears.

Tempering

The heat treating, which is used to increase the toughness of iron-based alloys. Tempering is usually performed after hardening, to reduce some of the excess hardness.

Annealing

A heat treatment process used mostly to increase the ductility and reduce the hardness of a material.
