SPRAY SUPPLIERS:
35 YEARS OF QUALITY SERVICE AND PRODUCT
Metal or thermal spraying is a
technology which protects and
greatly extends the life of a wide
variety of products in the most hostile
environments.
Thermal sprayed coatings have proven worldwide
to be the only coating providing long term
corrosion protection of structural steel with
examples of 40 or 50 plus years still in great
condition today.
Commonly used materials for thermal sprayed
corrosion protection are zinc, zinc/aluminium
alloy (85%Zn / 15%Al) and pure aluminium. The
choice of material to be used is a vast topic with
many factors to be taken into consideration.
Generally zinc is used, aluminium is used in
harsher applications such as high temperatures,
marine and splash-zone areas and under insulation
up to 590°C. Zinc/aluminium alloy is used in
environments where corrosion resistance needs to
be extended
The range of applications that metal sprayed
coatings are used for has mainly developed
as a result of the limitations of other available
processes. For example, large bridge sections
are often metal sprayed as they can be too large
for hot-dip galvanising. Other benefits are more
material can be applied providing longer life,
no size limit of the structure, no drying time, no
distortion, no chemicals used and can be applied
on site. The coatings can be left as sprayed,
sealed, powder coated or painted for aesthetic
reasons.
While anti-corrosion applications are the most
common use for metal spray, the technology is
also frequently used in engineering applications to
increase wear resistance in the life of components
and also to reclaim crucial parts that have worn or
have been damaged.
Thermal sprayed coatings also allow the
application of materials to protect substrates
subjected to harsh conditions such as erosion in
hydro power, chemical corrosion in oil and gas
vessels, gas turbines, high temperature and nonslip
coatings.
Copper has also been applied to various artwork
and sculptures as the ageing of the coating
provides a certain patina.
