At the National Manufacturing Institute Scotland (NMIS), we're leading the way in cold spray R&D as part of our ReMake programme, supporting manufacturers to extend component life, reduce waste, and cut emissions, especially in high-integrity sectors like aerospace, energy, and transport.
Key Insights:
-
Cold spray deposits dense coatings without melting, avoiding heat damage and distortion—ideal for high-value parts.
-
It offers a sustainable alternative to electroplated hard chrome, which is being phased out due to environmental and health risks.
-
The process requires minimal surface preparation and no post-heat treatment, making it efficient and scalable.
-
NMIS used cold spray to develop a high-performance repair solution, supporting circular practices like remanufacturing and refurbishment.
-
With a large working volume, adaptable nozzles, and multi-material capability, NMIS cold spray facilities can handle parts up to 3 tonnes.
-
The technology enables tribological coatings, wear- and fatigue-resistant surfaces, and even large-scale additive manufacturing.
-
Ongoing work includes developing new materials, in-process monitoring, and an international standard for cold spray in repair and AM.
