This involves heating applied rapidly and locally to the steel component followed by fast cooling (quenching). High frequency electric fields quickly heat the surface of the component via inductor coils, which is then quenched using water. This results in a localized hardened layer at the surface. Different shaped inductor coils are available and can be made to suit.
By using a coil-shaped conductor made of copper, induction hardening generates an electromagnetic field into which the material is placed. This creates an electrical voltage in the material itself, which in turn generates heat. As a result, the material receives the necessary hardening temperature. Both warming up time and time at temperature are reached quite quickly. The temperature can be regulated by the current strength on the coil-shaped conductor and by the duration of the power supply.
Induction Hardening offers a cost-effective low distortion surface hardening treatment to steels, particularly large components where an increase in surface hardness is required whilst maintaining core properties.
We have a hugely comprehensive range of handling equipment, which includes horizontal and vertical fixtures and the ability to manufacture special handling equipment to your individual requirements for small batch or high-volume production.
fields of application
Induction hardening is used for the hardening of surface layers. The microstructure is transformed by induction, for which the material must have a carbon content of at least 0,35%.
This method is used primarily for workpieces that are prone to wear on the surface, as well as for components with a complicated shape. Because advantages of induction hardening are i.a. the possibility of partially harden components in an uncomplicated way and the option of achieving extremely thick layers. In addition, the throughput times for induction hardening are comparatively short. The process requires special know-how and the use of complex tools and systems.
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.
