“Adoption of Cold Gas Spray in Additive Manufacturing and Repair Applications”
- A key emerging trend in the cold gas spray coating market is its expanding use in additive manufacturing and component repair, particularly in aerospace, defense, and energy sectors. The ability to deposit coatings without melting feedstock materials makes cold spray ideal for structural repairs and restoring dimensional tolerances on high-value parts
- For instance, OC Oerlikon has been investing in cold spray systems for on-site repair of turbine components and aircraft engine parts, reducing downtime and extending component life. Similarly, Praxair Surface Technologies offers turnkey cold spray solutions for coating and additive manufacturing applications in industrial sectors
- Cold spray's solid-state process minimizes oxidation and thermal degradation, enabling high-strength bonding and preservation of material properties especially important for aluminum, titanium, and magnesium alloys
- The trend also aligns with sustainability goals by reducing material waste and energy consumption during manufacturing and repair, positioning cold spray as a green alternative to traditional thermal spray and welding methods
- Companies such as Wall Colmonoy are leveraging cold spray technology to offer custom engineered coatings and repairs in critical applications, including aviation, oil & gas, and power generation
- This growing demand for non-destructive, efficient, and cost-effective material restoration is set to significantly expand the role of cold gas spray technology across industries worldwide
