What we do
Case hardening (atmosphere/vacuum)
Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of harder alloy.
Combined with a subsequent hardening operation the desired component properties can be varied to suit the application.
Our Carburising services
Atmospheric carburising
Carburising is a case hardening process that increases wear resistence, surface hardness and fatigue strength by creating a hardened surface layer and a tough core.
Low pressure carburising (LPC)
A case hardening process carried out at a very low pressure and elevated temperature to obtain a hardened surface layer of tempered martensite and a tough core.
Carbonitriding
Carbonitriding is an austenitic case hardening process similar to carburising. The addition of nitrogen creates a hardened surface layer increasing wear resistance.
Our Ferritic nitro carburising services
Corr-I-Dur®
Proprietary Bodycote thermochemical treatment for simultaneous improvement of corrosion and wear resistance through generation of a nitride-oxide combination layer.
Nitrocarburising
Nitrocarburising is a variation of the case hardening process. It is a thermochemical diffusion process where nitrogen, carbon, and to a very small degree, oxygen atoms diffuse into the surface of the steel part, forming a compound layer at the surface, and a diffusion layer.
Ferritic nitrocarburising – gas
Ferritic nitrocarburising involves the diffusion of nitrogen, carbon and oxygen into the surface giving significant improvements in fatigue properties, adhesive wear resistance and anti-seize properties.
Case hardening without subsequent hardening operation, also often generically referred to as nitriding, is the diffusion of nitrogen into the surface of special alloy steel to give a hard surface and soft core without the need for further treatment.
Our Nitriding services
Ion/Plasma nitriding
Plasma nitriding (or Ion Nitriding) is a plasma supported thermochemical case hardening that increases surface hardness, and wear and fatigue resistance by generation of a hard layer.
Gas nitriding
Thermochemical case hardening process used to increase wear resistance, surface hardness and fatigue life by dissolution of nitrogen and hard nitride precipitations.
Our Boriding/Boronizing services
Boriding/Boronizing
Boriding is a thermochemical surface treatment in which boron atoms are diffused into the surface of a workpiece to form borides with the base material.
