WHAT IS HIGH VELOCITY SYSTEM & WHY ?
The High Veloci ty
optionisarevolutionary
technology that has
allowed the arc spray
process to rival the
coat ing qual i ty of
higher-end processes
like plasma spray. The HighVelocityattachment increases particlevelocities
andconcentratesthespray pattern to producedramaticallyimprovedcoating
quality. Coatings are similar to plasma-sprayed coatings; however, with the
HighVelocityOption,theseplasma-likecoatingscanbeproducedinmuchless
time and at a fraction of the cost. Other advantages that the High Velocity
attachmenthasoverconventionalarcsprayare:
Higherparticlevelocities&depositionefficiencyDensercoating&superiorbondstrength.Focused,narrowspraypattern

MEC hasworkedcloselywithindustriestodeveloparcspraysolutionsforsomeofthe
most demanding coating applications. While most arc spray coatings still utilize
metallicalloycomposition,theadventandgrowthofengineeredcompositecoredwires
broadens the use of arc spray technology. For coatings ranging from simple
dimensionalrestorationtocomplexsurfacetreatmentrequirements,arcsprayprovides
competitivehighqualitysolutions.

Part Restoration
The nature&flexibility ofthearcsprayprocessenableseconomicalapplicationofthickcoatingswithout significantlossof bond strength. Forthisreason, arc spray has become the process ofchoicefor partrestoration in applications wherethe replacementcostsarehighortheparthastobe refurbished on-site. Examples are :crankshaft,rollsofpapermill&steelindustry.
Electrical Conductivityand resistivity

Arcsprayedcoatingsareusedforbothelectrical
conductivity and resistivity. In the electronics
industry, coatings such as tinareoften used on
nonmetallic parts because of their ability to
acceptsolders.
Wear Resistance
Cored wire technology has broadened thespectrum of arc spray applications. With atailored chemistry of materials, includingcarbide-bearing compositions. It is possible toproduce coatings with excellent sliding wearresistance as well as abrasion resistance at alowercostthanPlasma& HVOF.
Corrosion Protection
Arc sprayed coatings are used widely to fightboth highand lowtemperature corrosion.thesecoatings have proven their excellence inchallenging environments such as boilers, byproviding oxidation and heat resistance. Arcsprayed coatings also provide excellentresistance to atmospheric corrosion and areused on bridges and other infrastructuralcomponents.
