Induction Hardening Surface Treatment

hardening induction hardening surface treatment

Induction hardening is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.
Induction hardened metal components are able to last longer. The process of induction hardening treatment is fairly straightforward, but it requires specialized equipment. The advent of induction heating has made it possible to use electromagnetic energy that generates heat within the metals without taking up a lot of space or generating a lot of excess heat outside of the metal object that is being treated itself.

In order to make more quality products through induction hardening, you need to explore customized induction heating solutions. Induction heaters can be customized to the specific needs of the heat treatment application of the metal. Because there are variety of different industrial applications those uses of an induction heater, these machines can be built to a particular set of specifications. Induction heaters heat the metal without ever making contact with it. Heat builds up within the surface layer of the metal parts in response to the electromagnetic field surrounding it. The metal parts have been heated using induction and then quenched to produce increased hardness in the metal part.Induction power supply unit

Induction heating is appropriate for a large assortment of different applications involving a variety of different metals. The automotive industry uses induction hardened bearings, brakes, and shafts as well as gears and joints. Different projects in the marine industry and the railroad industry both need induction hardened product. The railway infrastructure depends on properly hardened work-pieces including rails. Engineering parts heated via induction and then quenched or cooled rapidly in order to get an appropriate level of hardness. Improperly quenched metals will tend to have low hardness values or variable hardness throughout the piece which can ultimately result in induction quenching cracking.
