Cold Spraying

Expert solutions to help you succeed

Cold spray bonds metal or ceramic powders to a surface using a high velocity stream of nitrogen or helium gas preheated to relatively low temperatures (up to 1000°C or 1800°F), but below the melting point of the powder. The process accelerates the particles to supersonic velocities, causing the particles to embed and form a strong bond onto the intended surface. This technology is especially effective for repairing worn parts in addition to adding unique coatings to manufactured parts.

Air Products offers a variety of technical services, gas-based solutions and a full line of industrial gases—oxygen, nitrogen, hydrogen, argon, helium and various gas blends for small and large volume users. Our applications engineers can work with you to understand your cold spray operation and recommend improvements that can help you optimize gas use and improve product quality.
