Thermal Projection

The process is based on continuous oxygen combustion of a fuel. Combustion gases entering a chamber , where the raw material in powder form injected axially through the flow stream of an inert gas , usually nitrogen.
The high gas pressures associated with geometries designed specifically to promote the acceleration of the same , allowing the coating material get speeds of the order of 300 m / s with a gas velocity of 2140m / s.

This process is especially designed for the application of high quality anti-wear coating , which is characterized by high hardness (approximately 1.200HV ) , low porosity (0.5-1% ) and high adhesion to the substrate (> 80 MPa) . Typical thicknesses of these applications varies between 50 and 400μm .
