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.
In cold spray coating applications, the consistent supply and purity of industrial gases are key factors for applying the high-quality coatings your end users demand. As a leading industrial gas company, we bring years of experience in gas supply and safety to help you improve your operation’s performance.
Air Products gases, typically provided in gaseous and liquid form, enable customers in a wide range of industries to improve their environmental performance, product quality, and productivity.
An inert gas for cryogenic, heat transfer, shielding, leak detection, analytical and lifting applications
Useful as a gas, for its inert properties, and as a liquid for cooling and freezing. Virtually any industry can benefit from its unique properties to improve yields, optimize performance and make operations safer.
