THE PROCESS

Solid particles. New possibilities.

Metal on metal.
Without the melt.

A high-speed stream of solid powder particles builds a coating on a prepared surface. The metal bonds through impact, rather than melting.

Low-pressure cold spray uses compressed air, an electric gas heater and a de Laval nozzle to accelerate particles. It opens a practical route to local repair and functional surfaces, with less melting-related thermal impact.

INSIDE LOW-PRESSURE COLD SPRAY

Follow the energy. Watch the coating grow.

From compressed air to a solid metal coatingAir from a compressor passes through an electrical heater. Heated gas accelerates in a converging-diverging de Laval nozzle. Powder enters downstream of the throat in this low-pressure schematic, is heated and accelerated by the gas, and impacts a prepared surface to build a coating without melting. 01 / COMPRESSED AIR02 / HEATING03 / DE LAVAL NOZZLE04 / PARTICLE IMPACT Powder inlet Compressor supplyElectrical heating elementThroatSolid particles acceleratePrepared substrateCompressed airHeated gasSolid powder / coating

01Supply

Compressed air flows from the compressor into the system.

02Heat

The heating element transfers energy to the gas.

03Accelerate

The nozzle converts gas energy into a high-speed stream. Powder enters downstream of the throat in this schematic.

04Deposit

The gas heats and accelerates solid particles. Suitable particles bond on impact and build the coating.

Illustrative flow, not a scale or speed simulation. Inlet position depends on nozzle design. Gas temperature is not particle temperature; the powder is not melted. Bonding depends on the powder, substrate and process conditions.

MAKE AN INFORMED DECISION

Clear answers. Better decisions.

A good fit?
Let’s be specific.

Cold spray is a process to qualify for a job. These questions help you decide where to start.

THE MOST USEFUL FIRST STEP

A small, measured trial.

Agree the target result, test a representative sample and review the evidence before committing to production.

Talk through your application
What is a promising application?+

An accessible surface needing local metal build-up or a functional coating, where the chosen powder can bond and the result can be tested. Substrate condition, nozzle access and service requirements matter as much as the equipment.

When might it be the wrong process?+

Poor nozzle access, unstable or contaminated substrates, unsuitable powders, or requirements outside a qualified coating’s performance may rule it out. Structural cracks and safety-critical repairs need an approved engineering procedure; a deposited layer alone does not establish safety.

Does “cold” mean there is no heat?+

No. The current CSM specifications list gas temperature at the nozzle inlet of 200–600 °C. This is not the particle or part temperature. The powder remains solid in the cold spray process, while the component may still heat up. Thermal effects must be checked on sensitive parts.

What does the workshop need?+

The supplied CSM specifications state 0.4 m³/min air consumption at 5–8 bar operating pressure, a maximum inlet pressure of 9 bar and up to 3.3 kW electrical power. Check air delivery under load, drying and filtration, electrical supply, appropriate dust extraction, powder handling and operator protection.

Can any metal powder be used?+

No. Composition, particle size, morphology, feed behaviour and the powder–substrate combination affect deposition. Use a compatible grade and confirm its technical and safety data. A powder name alone does not establish availability or compatibility.

How do we choose a system and estimate cost?+

Share the component, required coating, repair area, target thickness and expected quantity. The estimate should consider equipment, powder, compressed air, preparation, spraying, finishing and inspection. A trial helps establish realistic powder use and cycle time.

How should the workplace be arranged?+

Use a controlled spray area with suitable extraction, filtration and powder collection. Match these controls to the powder safety data and task. Plan clean powder storage, surface preparation, operator protection and inspection alongside the spraying equipment.

Can cold spray create conductive layers on PEEK?+

Preliminary development work has explored direct metal deposition on engineering polymers, including PEEK, for conductive and solderable surfaces. Gas settings, stand-off distance, powder composition and substrate preparation all matter. The results are a starting point for further testing, not a general rating for every polymer part. Validate adhesion, electrical performance, thermal cycling and environmental durability.

Where can I find model specifications and powder grades?+
