Cold Gas Spray Equipment
Cold Gas Spray Equipment is an industrial surface coating system used to deposit metal or alloy powders onto a surface without melting them. Instead of using heat like traditional spraying methods, it uses high-velocity gas to “blast” particles onto a surface where they bond mechanically.
👉 In simple terms:It is a coating technology that uses speed, not heat, to build protective metal layers.
⚙️ How Cold Gas Spray Works
A high-pressure gas (usually helium or nitrogen) is heated moderately
Metal powder (like aluminum, copper, titanium) is injected into the gas stream
Gas accelerates particles to supersonic speeds
Particles hit the surface and deform and stick instantly
A dense, solid coating builds up layer by layer
👉 No melting occurs—this is a solid-state deposition process.
