Nitriding
is a heat treating process that diffuses
nitrogen into the surface of a metal to create a case hardening effect.The
typical applications include gears,crankshafts,cam,followers etc.Nitriding is
used to generate unique structural properties associated with strong mechanical
properties.The aim of the process is to diffuse nitrogen into the substrate
surface to form nitrides in combination with different alloying elements of the
substrate and form compound layers that have high wear resistance properties.
Advanced
Nitriding solutions is a premiere commercial plasma ion nitriding company that
facilitates will excellent and unique plasma ion nitriding solutions.
Nitriding Solutions changes the
chemical composition of the surface of the substrate and the process is carried
out at medium temperature also classified as thermo chemical process.When
carburizing , a phase transformation occurs when cooling the substrate since
the process is held at temperatures were
the stable phase of steel is austenite.
Nitriding Solutions impart :
·
High surface hardness and wear strength
·
High resistance to tempering and
high-temperature hardness
·
High dimensional stability compared to
other heat treatment process
The advantages of Gas Nitriding processes can be
surpassed by plasma nitriding.When applied to higher alloyed steels,plasma
nitriding imparts a high surface hardness which promotes high resistance to
wear,scuffing,galling and seizure.In gas nitriding, ammonia is fed into a
closed chamber where the parts to be nitride are placed and heated to a
temperature of about 510 °C.
Plasma nitriding is a smart choice whenever parts are required to have both
nitrided and soft areas.This process is also known as ion nitriding or glow
discharge nitriding in which is enhanced by a plasma discharge on the part to
be nitride.The plasma is a gas that when exposed to an electrical potential is
ionized and glows.
The
advantages of the plasma ion nitriding process are :
·
Environment friendly
gases: Plasma nitriding uses as process gases, nitrogen,hydrogen and argon
mainly,which are not harmful for people or the environment.
·
No fire risk : Even
though hydrogen may be dangerous, in case of plasma nitriding there is no risk
of fire.
·
Low process gas consumption: This
together with low energy consumption, results in low operating costs.
