Cold Spray Coatings
Coating technology without thermal stress
Cold spray coatings offer an advanced, high-strength, oxide free solutions for the protection and restoration of rollers and industrial parts without relying on high temperatures. Unlike traditional thermal spray processes like plasma or HVOF that involve melting coating materials, cold spray technology mechanically bonds particles to surfaces at supersonic speeds. This unique process minimizes thermal stress, making it ideal for applications requiring durability and precision.
What is high and low pressure cold spray coating?
Cold spray coating is a process in which fine metal or alloy powders are accelerated to supersonic speeds using a high-pressure gas stream, typically nitrogen or helium. These particles, propelled at high velocity, collide with the surface of a part and bond through mechanical interlocking. Since the particles do not reach temperatures as high as in other thermal spray processes, this "cold" process, prevents the thermal distortion of the coated component. Cold spray coatings form dense, highly adherent layers with excellent material properties.
