Brass Nozzle for Gas-Dynamic Cold Spraying Technology

The Laval nozzle in gas-dynamic cold spraying technology plays a key role by enabling the acceleration of the gas and metal particle stream to high speeds. Due to its shape, which first narrows and then expands, the nozzle accelerates the gas flow to supersonic speeds. In the narrow part of the nozzle, metal particles reach high velocity, and as it expands, this speed increases even more. This is crucial for the process, as particles at such speeds effectively deposit on the surface, creating a durable coating.
