Twin Wire Arc Spray Thermal
Coating Process
|
The basic Arc Spray
process illustrated below shows the two wires being fed into the gun.
One is negatively charged and the other positively charged. When the two
wires make contact, they are instantly melted, broken down into minute
particles and forced by air pressure at the substrate surface. They
impact at about 1200 feet per second. |

There are 50+ alloy wires to choose
from, including...
|
|
Stainless Steels |
Chrome |
Zinc |
Copper
|
Bronze
|
Tungsten
Carbides
|
|
Babbitt
|
Nickel
|
Titanium
|
Aluminum
|
Tin
|
Molybdenum |
|
All
wire stock can be blended to give matching or enhanced
characteristics of the original substrate material. |

Advantages… |
|
|
Cost Effective - |
Using
compressed air and electricity makes it one of the most
economical spray processes. |
|
Large Build Ups - |
High volume
application and low heat makes it easy to rebuild a large wear
area, which also results in a fast turn around time. |
|
Low Heat Application - |
Temperatures
on the surface being sprayed can be kept as low as 150° F during
application. This will ensure no metallurgical damage or
distortion to the component being sprayed. |
