📌Twin wire Arc spray process is most suitable for TSA coating, in this process two wires of desired material (99% Aluminium wire) act as electrodes, when they are fed through a spray gun.

📌The spray gun connected to high-current DC power source to facilitate an arc between them. An air stream to the back of the gun atomizes and propels the molten particles towards a prepared surfaces.

📌White metal blast cleaning is the suitable surface preparation method for TSA coating, the surface should free from any contamination with 75 to 110 microns surface profiles.

📌Safety is more important to this process, so competent professionals only can handle this spray process.

📌Mandrel Bend test and Dolly pull-off adhesion test to be performed to evaluate the TSA Coating.

📌Sealer coat shall have sufficiently low viscosity to penetrate the pores and seal the surface of the thermal spray coating.
