Metallizing wire coating is done through melting and
projecting the molten wire material on a substrate. Different thermal spraying
processes used to apply these coatings include different methods, devices and
heat sources. The spray materials are commonly used in wire or rod form. With
the passage of material through spray unit they are heated to a molten or
semi-molten state and then atomized or accelerated and carried to the substrate
in this form.
The heating is performed by gas flame, electric arc, plasma
or detonation of a combustible mixture. The hot particles are conveyed from the
spray system to the substrate through the gas jet that also accomplishes the
atomization and particle acceleration.
Metalized wire coatings
secure the base metal far longer than ordinary paint and offer prolong
successful functionality of the components. Therefore metalizing wires are used
in diverse applications such as:
·
Coatings in aircraft engines
and overlay for medical implants
·
Act as self bonding as general
purpose, moderate hardness, hard and wear resistant
·
Dense coating for high
temperature and oxidation resistance. Bonding is much better than molybdenum
·
Self bonding for supreme
oxidation resistance and supreme machinability
·
Self bonding on the clean and
smooth metallic surfaces. Coating is dense, fully adherent and resistant to
oxidation
·
High temperature resistance to
diverse acidic and chloride media. Outstanding oxidation resistance up to
1800oF
·
Coating of components that need
elevated temperature resistance to various corrosive media
·
Highly machinable alloy coating
for wear and corrosion resistance
·
Coating for outstanding wear
and corrosion resistance
·
Coating for Corrosion and load
bearing resistant surfaces in marine water and caustic media.
·
Coating to prevent stress
corrosion, cracking and chlorine media by 1800oF
·
Coating as an overlay for different
300 stainless steel series. Average corrosion resistance and dimensional
stability
·
Protection at elevated temperatures,
coating is advantageous as an overlay
·
Bright coating with additional
benefits of oxidation resistance, corrosion and heat resistance
·
Coating is advantageous for
repair and salvage of automotive cracked blocks, heads and similar castings,
mold patterns and latheways
·
Dense coating that is nominal
to slightly porous with minor oxide concentration. Outstanding for fretting
wear applications.
·
Coating is beneficial for good
stress rupture, endurance and creep characteristics. Supreme for oxidizing and
reducing media up to 2100oF.
·
Coating as a bearing surface
with supreme resistance to fretting, cavitational wear and for salvage and concentration
of brass and bronze surfaces
·
Coating is easy to machine and
can be used in aircraft engine seals
·
Coating can replace brazing and
used in electrical appliances
·
Attains supreme electrical and
heat conductivity, develops dense, corrosion and oxidation resistant coatings.
·
Harder coatings for repair of
damaged substrates.
Industries where metalizing wire is commonly used are:
·
Automotive restoration
·
Bridge
·
Structural steel work
·
Painting
·
Pipe producers
·
Anti-skid coatings
·
Deck coatings
·

·
Boiler repair
·
Arts and crafts
·
Corrosion control
·
Steel and concrete structures
·
Windmills
