Vast technological possibilities |
|
 |
Ion nitriding is a method with vast
technological possibilities. Diffusion
layers of desired structure can be
obtained, i.e. the diffusion saturation
process is controllable and can be
optimized in accordance with the
particular requirements to the layer
qualities. By regulating the gaseous
phase composition and the pulse glowing
discharge parameters diffusion layer
with monophase-γ'-zone(Fe4N), with
monophase-ε-nitride zone(Fe2-3N) or
nitrided layers without any nitride zone
can be obtained.The achieved nitride
zones are dense and solidly connected
with the base metal. |

Ion Nitriding has the following
advantages compared with classical gas
nitriding: |
|
 |
-3 to 10 times reduced duration of
treatment;
-50% - 100 % less energy consumption;
-50 to100 times less working gas
consumption;
-
Distortion - less distortions because ion
nitriding is performed at lower
temperature and under a vacuum;
-
Higher surface, case and core hardness;
-
Excellent wear resistance - the ion
nitriding process produces a compound zone
which is dense, nonporous, very hard, not
brittle, and has a low coefficient of
friction;
-
Reproducible results and better control -
the technological process of ion nitriding
is fully automated and computer
controlled. The heat for ion nitriding is
generated on the surface of the details by
ion bombardment of their surface and
therefore the details are heated
uniformly;
-
Surface finish
-due to minimum deformations no
additional mechanical treatments are
necessary;
-necessity of predepassivation of
stainless steel is eliminated;
-
Masking - surfaces which require masking
are easily masked with reusable mechanical
masking devices - 100 % effective.
-
Excellent hygiene and working conditions -
the process is not toxic and coresponds to
all modern requirements of environmental
control.
