CLIN : surface treatment as protection for wear and
corrosion stressed parts
Global benefits
• Very good wear resistance
• Good friction properties
• Excellent scuffing / seizure protection (adhesive wear) thanks to ceramic
charactreristics of the surface
• Excellent corrosion protection
• Good surface fatigue resistance
• Decorative black surface
• No deformation of the part
Thermochemistry
• Environmental respect thanks to "zero waste" concept
6
• No distortion → treatment done on finished parts

Description
Degreasing /Rinsing
Remove oils, and other
particules from the surfaces
of the parts
Preheating
Keep a stable temperature in
the nitrocarburazing melt
Nitrocarburizing
Surface structure
Oxidizing
• Corrosion protection
• Black aspect
Cooling / Cleaning
Remove salt from the surface
of the parts
Mechanical finishing
• Smooth surface
• Low roughness (no lower
than before treatment)
• Friction properties
HEF has know-how in :
• Shot blasting
• Tribofinishing
• Centerless polishing ...
Impregnation
• Improve corrosion
resistance
• Bright aspect
HEF impregnation used :
• Corolac (dry aspect)
• Corofluide (oily aspect)
The iron nitrides (Fe0) composing
the porous outside layer of nitrided
surface will be changed in stable
iron oxydes (Fe304)

Benefits of the software
• Processes (Ex ARCOR BVGD2-5) are defined in the software
• Control of process parameters (alarms)
• Actions (changing of step) are announced by the computer
• The action is manually done by the operator (hoist)and
validated on the computer
Thermochemistry
• Each action is recorded (Time, process parameters,…)
14
• Water is automatically added in the rinsing cascade after each
load passage (minimize consumption of water)
• Internet connection possible from HEF headquarter

• Reproductibility (gas nitriding parameters: parts
Thermochemistry
quantity, parts cleanliness, gas volume in furnace,...)
• Uniformity (homogeneity of temperature and
chemical composition of the salt)
22
•
•
•
•
•
•
•
•
Better corrosion resistance
No fragile white layer (thanks to Epsilon nitride )
Better wear resistance (thanks to Epsilon nitride )
Less distortion risk (because of gradual cooling)
Shorter cycle time (highest nitrogen potential)
Stainless steel depassivation efficient
Less polluting
No unintentional masking (all the part in contact
with salt)
• Cleaning results do not play a such important
role
• Masking difficult
• Impossible treating large
components

The HEF group is the nitrocarburizing technology
worldwide leader
ARCOR treatment is a thermochemical Oxynitrocarburizing
treatments which enrich the surface of ferrous materials with Nitrogen
and a small amount of Carbon both present in the salt, and which
create on the external surface of the material a hermetic iron nitrides
layer offering high corrosion resistance, good friction properties and
wear resistance.
ARCOR V®:
28
Standard process
ARCOR BV® :
With a final polishing step offering a low surface roughness and
a bright black aspect
ARCOR PV® :
With polishing and a final post oxidation step offering a low
surface roughness and a uniform black aspect

Hard Chromium Vs Nitrocarburizing
Summarize of ARCOR treatment advantages
ARCOR process Vs Hard chromium plating
+++
•
•
•
•
•
Higher corrosion resistance in Salt Spray Test (SST)
Similar corrosion resistance in Copper Accelerated Acid Salt Spray test (CASS)
No risk of failure due to hydrogen embrittlement
Cr 6+ free (toxic hexavalent chromium) – No concerned by REACH
No peeling nor flaking (because the layer becomes an integral part of the base
material)
•
•
•
•
•
•
34
No micro cracks
No grinding after treatment
Dent resistance thanks to the ductile surface
Mechanical surface resistance thanks to the Nitrogen diffusion
Better lubrication retention thanks to the external porosity surface
Similar seals and guiding components than for hard chromium plating
