Thermal Coating

In this process, we utilize two metallic wires that are electrically charged with opposing polarity as the coating feedstock. This will cause them to throw a molten arc between each other. We will next inject inert gas or high velocity air, to trigger an atomization of the now-molten material and propel onto the substrate to form the coating. If you opt for the electric arc spray process, we can spray any type of metals which have melting points below 5000°C.

Depending on the equipment being used and the material being applied, A&A Coatings can provide metallic coatings with either, semi-metallurgical bonds or mechanical bonds up to 5000 P-S-I. Distortion will not occur because the substrate is not exposed to high temperature over 120°C.

Metalizing Coating Process | Combustion Wire Spray

In this process, we feed the spray material in wire form into a fuel gas-oxygen flame where it is melted by the heat (temperature up to 3000°C) of that combustion. Compressed air is concentrated around the flame, atomizing the molten material into fine spherical particles and propelling these particles at high velocity onto the substrate.
We can manipulate the atomization and the melting of metals with different melting points when we control the feeding rate of the wire through the flame. When you opt for this method, we can spray any wire as long as it features a melting point below 3000°C.

Advantages of Metalizing

  • To achieve insulation
  • Resistance to corrosion
  • Significant cost advantages
  • Not subject to degrading
  • Anodic protection of surface
  • No cure time or temperature to limit metalizing
  • Stronger adhesion than paint
  • Longer lasting than paint
  • Faster and more productive
  • Surface roughness no more than 0.05 mm
  • Pure metals and alloys can be sprayed
  • Can be operated under extreme temperature conditions
