Pulse Plasma Nitriding
for Aerospace Applications

Intro
Cov
hen aerospace manufacturers
seek to improve the
reliability and durability
of common materials such
as aluminum, stainless steel, and titanium,
advanced surface treatment casehardening
options are significantly enhancing
wear resistance, fatigue and
material performance.
Lightweight aluminum and its alloys
are still used in machinery and engine
components due to its relative strength
and corrosion-resistance. Stainless steel
alloys are utilized in aircraft components
that require great strength and
can handle increased weight, such as actuators,
fasteners, and landing gear components.
Due to its superior strength-toweight
ratio, titanium is often used in
machinery, engine components, hydraulic
systems, and the aircraft structural
frame.
Traditionally, however, surface treatment
has involved one-of-three processes:
carburizing, salt-bath nitrocarburizing
and gas nitriding. Each process has advantages
and disadvantages, but those seeking
more precise control of the diffusion
layer formation, depth of case hardening,
and preservation of component dimensions
are increasingly turning to advanced
pulse plasma nitriding.
Although pulse plasma has been utilized
for decades, superior controls for
the DC pulsing signal, along with improved
chamber design and construction,
allow for more precise temperature
control and uniform distribution
of the heat zone throughout the hotwall
chamber. The result is extremely
consistent and uniform nitriding batchto-batch,
with less gas consumption.
" The benefits are more precise control
of the diffusion layers, and its
broader appeal to heat treat more diverse
materials, beyond steel, that include
titanium, stainless steel, and even
aluminum. " says Thomas Palamides,
