The
principle of Esonix UIT is based on the instrumental
conversion of harmonic oscillations of an acoustically
tuned body into resonant impulses of ultrasonic frequency.
The acoustically tuned body is brought to resonance
by energizing an ultrasonic transducer. The energy
generated from these high frequency impulses is imparted
to the treated surface through the contact of specially
designed steel pins. These transfer pins are free to
move axially between the resonant body and the treated
surface. Click here if you wish to read a white paper
on the "Physics of Esonix UIT".
Depending
on the desired effects of treatment a combination of
different frequencies and displacement amplitude is
applied. These frequencies range between 27 kHz and
55kHz, with the displacement amplitude of the resonant
body of between 22 and 50 microns.
The following list
describes the beneficial effects that can result due
to treatment. The controlled action of the application
allows one to define the exact combination of effects
listed below by altering the configuration of the control
and treatment parameters. Thus, the user only gets
those effects that are desired.
- Formation of a white
layer up to 10 microns in depth with exceptional
corrosion resistance, abrasion resistance, and lubricity.
- Plastic
deformation of the surface.
- Elimination of tensile
stress and the introduction of favorable compression
stress up to 12 millimeters in depth.
- Altering
the surface finish resulting in a smoother surface
and eliminating defects.
- Improvement in endurance
and corrosion resistance. Up to 250% and 400% respectively.
These changes in material characteristics provide
substantial improvements in both the utilization
and manufacturing of metal structures. These include:
- Increased
operational life in applications subject to dynamic
loads or aggressive environments.
- Reduced
maintenance cost of metal structures subject
to corrosion-fatigue destruction.
- Decreased
cost of manufacturing and operation through the
use of less material.
- Increased use of high
strength steel alloys previously limited by weld
properties.
- Increased structural stability
during manufacturing and operation.
- Operational
and maintenance cost reduction.
