The equipment

 
 

CLIN treatments are flexible processes necessitating suitable equipment.

Standard equipment in the Techniques Surfaces network.
 
The treatment stages are carried out on a line, the parts being positioned on a specific tool, and these stages can be described as below:
 
 

Stages:

Aims:

Degreasing / Rinsing

To eliminate the oil and other foreign particles from the surface of the parts

Preheating

To avoid thermal shock

To keep the nitrocarburizing oven at the setpoint temperature

Nitrocarburizing

To create a combination layer together with a diffusion zone

Passivation*

To carry out staged quenching so as to limit deformation

To create magnetite embedded in the porous surface

Water quenching

To fix the nitrogen atoms in the material

Cascade rinsing

To eliminate any trace of salt

Mechanical cleaning / Polishing*

To reduce surface roughness

Impregnation*

To seal the combination layer

 (*)Optional stages depending on customer specification.

The equipment is, however, combined with a suction, air purification and liquid waste treatment system with the aim of limiting their presence to the solid state and therefore of limiting their impact on the environment.

 
 
With the aim of providing our customers with perfect traceabilityperfect control of our parameters and therefore repeatability of our processes, our production equipment is computer-aided:
 
  • Each treatment is thus defined in the software,
  • Continuous control of the time and temperature parameters (alarms),
  • Each action is announced then validated by the software,
  • Recording of the parameters for each stage of the treatment,
  • Internet connection for remote control.
