Thermal Coating

TWAS is used primarily in the industrial semiconductor industry. Unlike other thermal spray processes, it does not use external heat sources. Instead, two electrically opposite charged metal wires are fed together so a controlled arc occurs at an intersection to cause heat and melting. The molten metal is atomized and applied to the substrate with compressed air or gas.
Type of coating materials: Al, AlSi, Cu, SST and other.

This thermal spray process combines a high temperature, high energy heat source with an inert spraying medium and high particle velocities. It is effective on a wide range of materials, including almost any metal or ceramic substrate. When the plasma cools, it creates an industrial-strength protective coating with exceptional bond strength and little to no damage to the substrate. Plasma coating protects parts from corrosion, wear, heat, oxidation, and abrasives and enhances electrical resistivity and conductivity.
Type of coating materials: Al2O3, Si2O3, Y2O3, Zi2O3 and Other.
