At Cold Metal Spray

We have been using and developing gas dynamic cold spray for 12 years. We’ve become experts in this innovative technology. We firmly believe in this revolutionary technology. We have many examples of where it has been applied with great success …

Our Technology

Cold Metal spray is a unique process that revolutionises the repair and build-up of metal. Our process uses innovative gas dynamic technology to repair worn, cracked, corroded and damaged components. It is also used to apply metal coatings. There is no melting of materials with virtually no heat input so distortion and cracking does not occur. Our systems are portable so work can be carried out at customer’s sites. This process is cost effective and is proven to save valuable components from being scrapped.

Development

Cold spray was discovered in theory during the late 1920’s. Development started in the mid-1980s during space industry research. A discovery was made, realising minute metallic particles bond with a substrate and themselves when they impact a surface at supersonic speeds. The discovery that metallic particles could bond based solely on their kinetic energy was investigated further in later years and ultimately, the technology was developed under the name Cold Spray.

The result

Because the adhesion of the metals is not based on a melting process, this technology eliminates all the detrimental heat-related effects, e.g. stresses and strains, associated with other thermal processes. Cold Spray technology is viewed as being the newest member of the thermal spray family, yet can be regarded as being in a class of its own thanks to its unique characteristics.
