SX-LP60 Cold Spray System

Cold spraying (CS) is a novel thermal spray technology that operates on the principles of aerodynamics. It utilizes high-temperature, high-pressure gas to carry powder particles axially into a Laval nozzle within the spray gun, generating a supersonic flow. After being accelerated to speeds ranging from 500 m/s to 1200 m/s within the spray gun, the powder particles impact the substrate in a fully solid state, causing plastic deformation and depositing onto the substrate surface to form a dense coating.

Product Description

SX-LP60 Cold Spray System

Cold spraying ( CS is a novel thermal spraying technique that, based on aerodynamic principles, uses high-temperature, high-pressure gas to carry powder particles axially into the Laval nozzle of the spray gun, generating a supersonic flow. After being accelerated by the spray gun to speeds ranging from 500 m/s to 1200 m/s, the powder particles impact the substrate in a fully solid state, causing plastic deformation and depositing onto the substrate surface to form a dense coating.

It can be used to prepare coatings with high thermal conductivity and high electrical conductivity; has minimal thermal impact on the substrate; exhibits extremely slow grain growth (potentially maintaining a nanoscale microstructure); closely resembles forged microstructures (with higher hardness compared to conventional coatings); and features stable phases and chemical composition. Coating thickness can reach 10 cm or more.

Its main advantages include a coating that is virtually free of oxides, excellent density, high deposition efficiency, and broad applicability to various materials.

It is applicable to plastic-deformable metal powders and composite powders containing plastic-deformable material components; the spraying range of metals extends from low-melting-point zinc to high-melting-point titanium and niobium.
