NiAl 80/20 Thermal Spray Wire

Thermal spraying refers to a series of processes in which fine and dispersed metallic or non-metallic coating materials are deposited, in a molten or semi-molten state, onto the surface of a prepared substrate to form some kind of sprayed deposit. The coating material may be powdery, ribbon-like, filament-like or rod-like. The thermal spraying gun provides the necessary heat by fuel gas, arc or plasma arc, heating the thermal spraying material to a plastic or molten state, and then subjected to the acceleration of compressed air, so that the constrained particle beam impact on the matrix surface. The particles that hit the surface are deformed by stamping, forming laminated sheets that adhere to the prepared substrate surface and then cool and accumulate, eventually forming a layered coating. Due to the different coating materials, the coating can achieve high temperature corrosion resistance, wear resistance, heat insulation, electromagnetic wave resistance and other functions.
