SURFACE TREATMENT

In order to provide a complete service to our customers, TSGO completes our value chain by specialising in surface treatment. We carry out treatments by ion nitriding and induction hardening.

Controlled Ion Liquid Nitriding (CLIN) is the family name for the various nitriding treatments. It is carried out at a temperature ranging from 480°C to 630°C and enriches the surface of ferrous metals with nitrogen and a small amount of carbon.

 ARCOR combines thermochemical diffusion in salt baths with passivation and a finishing treatment. It combines corrosion, wear and fatigue resistance properties on steels and cast irons. Corrosion resistance can exceed 700 hours in a salt spray on single parts and is commonly 400 hours in a salt spray on complex parts with crimped or welded joints.

 Induction heat treatment can be partial or localised. It allows the surface of the material to be

hardened while maintaining good resilience in the core of the material. The part is heated to a high temperature and then cooled, both in a very short time to avoid thermal diffusion in the material. The induction process allows the heating to be localised by acting on two criteria: the frequency of the inductor and its shape to induce a homogeneous heating without heat diffusion in the core of the part. It increases hardness, resistance to wear by friction, resistance to fatigue under non-uniform stresses (bending, torsion) or rolling under heavy load. In addition, it produces low deformation and has the possibility of tempering or partial annealing.

We also improve the surface finish by bead blasting or polishing to control the roughness of your parts.
