In the electric arc spray process,
the raw material, a pair of metal wires, is melted
by an electric arc. The molten material is atomized
by a cone of compressed air and propelled towards the
work piece. This spray solidifies when it hits the
surface of the work piece to form a dense coating,
which protects against corrosion or reclaims/repairs
components. Sprayed coatings may also be used to provide
wear resistance, electrical and thermal conductivity,
or for freestanding shapes.
Major advantages of the arc spray process are that
the coatings are available for almost immediate use,
with no drying or curing times; there is no risk of
damaging the component; the deposits possesses a higher
degree of bond strength than most other thermally sprayed
deposits; the use of only compressed air and electricity
mean more economic coatings.
Another mayor advantage is that spray is not a heating
process, therefore, do not produce mechanical deformations.
One of the more important applications is part restoration.
It is possible, in an economical way, to apply thick
coatings on any component, without loss of strength.
Moreover, it is possible to apply coatings with excellent
sliding wear resistance as well as abrasion resistance.
Based on years of laboratory and
field experience, TBA Arc Spray 300 is an easy-to-operate,
robust system designed for maximum application
The gun is light (~1Kg), easy to work and very
strong. In fact, allows real continuous work.
Carefully controlled head/wire geometry ensures
precise atomizing and reliable variety of spray
patterns, with wires sizes of 1,6 or 2 mm.
The gun has a "push" wire design and
allows hoses of 4 mts long.
Power unit (H class) is specifically designed for
Arc Spray, provided with 10 voltage steps, and
with a very efficient cooling system. When we specify
100 % working cycle this means continuous use.
