Nitrocarburizing is a process for surface hardening of materials. As a result of thermochemical diffusion, the surface layer of the material is enriched with nitrogen and carbon. In contrast to this is nitriding, a process in which only nitrogen is deposited in the surface layer. The compound layer formed through nitrocarburizing is generally thicker, more corrosion resistant and often takes the form of Epsilon Iron Nitride.
Nitrocarburizing can be carried out in different media. The process can take place in gas, in a salt bath or in plasma. In addition, the process takes place at relatively low temperatures. The result is a very hard surface layer, a thin connection layer and the remaining soft core of the material itself. The connecting layer is particularly resistant to corrosion and wear. In contrast to nitriding, however, it is not brittle. This layer therefore contributes significantly to improving the material properties.
The advantages of the process can be seen in the high wear resistance of the material and in the low costs for the treatment.
In addition, a good surface quality is created and the susceptibility of the material to corrosion is reduced. This method can also be used to surface harden elements that have not been pre-tempered.
fields of application
Nitrocarburizing is more commonly applied to low alloy steels, mild steels and cast irons, but can equally be applied to any steel which is thermally stable at the treatment temperatures.
Wir bieten weltweit alle Arten von Wärmebehandlungsprozessen an. Unsere Anlagen sind logistisch eng miteinander verknüpft, so dass Ihnen alle Verfahren zur Verfügung stehen. Erfahren Sie mehr zu unseren Wärmebehandlungsverfahren.
Heiß-Isostatisches Pressen (HIP) dient der Beseitigung von Porosität. Sie benötigen bei Lötverbindungen eine hohe mechanische Haltbarkeit und Unempfindlichkeit bei hohen Temperaturen? Wir bei Aalberts surface technologies bieten die Lösung durch Hartlöten (brazing).
Polymerbeschichtungen können auf viele Grundmaterialien aufgebracht werden und bieten lang anhaltenden Schutz. Sie sind mechanisch besonders gut mit dem Untergrund verankert und bieten verbesserte Gleiteigenschaften und/oder hohe Verschleißfestigkeit.
Mit 40 Jahren Erfahrung in der kontinuierlichen Veredelung von reel to reel können Sie sich auf Aalberts surface technologies verlassen, um innovative Lösungen zu finden. Unser Service umfasst Trommelgalvanik, kontinuierliche selektive Galvanik und Gestellgalvanik.
Fast alle metallischen Grundwerkstoffe können mit unseren selbstentwickelten und patentierten Verfahren durch Oberflächenbeschichtungen in ihren Eigenschaften optimiert werden, egal ob sie besonders hart, glatt, verschleißfest oder korrosionsbeständig sein sollen.
We offer all types of heat treatment processes. Our facilities are closely interlinked in terms of logistics, which means that all processes are available to you. For a complete list and description of heat treatment technologies please select the button.
Hot isostatic pressing (HIP) is used to eliminate porosity. Do you need high mechanical durability and insensitivity to high temperatures for solder joints? We at Aalberts surface technologies offer the solution through brazing.
Polymer coatings can be applied to a wide variety of base materials and offer long-lasting protection. They are particularly well anchored mechanically to the substrate. Additional enhancement layers allow non-stick coatings to be combined with improved sliding properties and/or high wear resistance.
With 40 years of experience in continuous reel to reel finishing, you can depend on Aalberts surface technologies to find innovative solutions that other companies might say are impossible. Our service includes barrel plating, continuous selective plating and rack plating.
Almost all metallic base materials can have their properties optimised by surface coatings using our proprietary and patented processes, regardless of whether they should be particularly hard, smooth, wear-resistant or corrosion-resistant.
