MUlTiFUNCTIONAl SURFACE TREATMENTS
ARCOR" treatments have been developed to
provide multifunctional surface properties. They
simultaneously enhance the wear, seizure, surface
fatigue resistance and corrosion resistance (can
now exceed 800 hours as per neutral salt spray
testing), These treatments comply with the increa-
singly severe operating conditions required on steel
or cast-iron based mechanica I components.
ARCOR®
CHROME 10IJm
The ARCOR'" series is based on oxynitrocarburizing
followed by various post-treatrnents, and offers an
efficient, economical solution, complying with the
environment proteetion regulations.

State-of-the-Art solutions via the CLlN"" technology
(Controlled Liquid lonic Nitriding), developed by
HEF"" Groupe, ensure a real optimization of the
treatment parameters.

CLIN™: AN ADVANCED TECHNOLOGY
The CliN™ technology is based on the most recent
developments in the field of liquid oxycarbonitriding
of HEF™ R&D, research center of HEF™ Groupe.

Components are processed in an ion ic liquid
medium. The liquid state during the treatment
provides homogeneous surface properties whatever
the shape of the components. It also contributes to
the absence of part deformation and thermal shock
effects.CROSS SECTION OF A LAYER OF A

E IRON NITRIDE LAYER ASPECT
This CliN™ technology allows accurate control of
both nitrogen and oxygen concentrations at the
surface of the components. This technology results
in a series of multifunctional treatments where
frictional properties, surface fatigue resistance and
corrosion resistance can be adjusted to fit a parti-
cular application.
Post treatments like polymer impregnation, high
quality surface polishing have been developed to
further increase the corrosion resistance of treated
components (more than 800 hours as per ASTM
B117 test), or to adjust the surface roughness for
low friction against polymerie sealing components.
This technology can comply with the most stringent
environment protection regulations with a zero
liquid and gaseous waste. concept, an solid waste
recycling.

The ARCOR" series offers the widest range of
surface treatments for components that require
either single or combined frictional properties, anti-
seizure behaviour, corrosion and surface fatigue
reststances. The surface properties of all types of
ferrous materials could be improved with the
ARCOR" treatments (steel, cast iron, sintered
ferrous alloys...).
Via the ClIWM technology the ARCOR" treatments
allow one to adjust the nitrogen and oxygen concen-
tration at the surface of the parts. In combination
with the, adjustme~f of process parameters' like time
and temperature (frorn 490°C to 630°C), and 'pre
or post heat treatments, specific properties can
be achieved (corrosion resistance, anti-seizure
behaviour, brinelling resistance). The ARCOR"
series can also be combined with heat treatments
like carburizing, induction hardenlng. Components
processed with these combined treatments exhibit
high volumic and sub-surface mechanical properties
together with friction and corrosion resistance
properties.
Today recognised as a standard surface treatment in
automotive industry with its C vers ion, the ARCOR®
series is completed with the new N and V types,
providing respectively extreme corrosion resistance
and outstanding superficial mechanical properties.
