Plasma Electrolytic Oxidation:
The Future of Lightweight Designs
in Aerospace and Defense
A
erospace and defense (A&D)
components face a range of
extreme conditions for prolonged
periods. Their lifespan
quickly becomes diminished as a result
and become susceptible to critical faults.
Because of this, vital components have traditionally
consisted of heavy alloys due to
their tensile/yield strength, high thermal
resistance and corrosive protection. Moving
into next generation designs, the lightweighting
of aircraft design has become a
priority to improve fuel efficiency,
enhance speed, and provide more available
carry weight for vehicles in action.
To support the advancement of using
lighter metals in A&D designs, metal coating
technologies have been developed to
protect and extend the lifespan of critical
components; especially those facing strenuous
conditions. That said, traditional
coatings can often fail to provide suitable
protection to replace heavy metals, and
also produce waste materials that are harmful
to the environment.
Plasma Electrolytic Oxidation (PEO) is
a unique surface coating technology that
specializes in light metals, aluminum,
magnesium and titanium specifically. It
enables the lightweighting of components
that face extreme environments
from a reliable and effective coating process.
Moreover, it provides full customizability
of coating characteristics to maximize
component lifespan in specific
conditions. So much so that it was used
to coat sensitive equipment on the James
Webb telescope in the extreme cryogenic
conditions of space.
In order to understand the true
impact PEO can have on the A&D
industry, one first needs to understand
the challenges of using these light metals
in designs, and the metal coating
process itself.
