Cold spray has come a long way in recent years. Developed by Soviet scientists in the 1980s, it's since been developed into an advanced technique for building, coating and repairing parts. So, what exactly is cold spray AM – and how is it changing the future of manufacturing?
Cold spray is a powerful technique for rapidly fusing powdered metals, ceramics, or polymers without melting them. It can be used to quickly repair worn or damaged components – or as a form of AM to rapidly build parts layer by layer.
There are two types of cold spray that we use to provide a range of services and capabilities:
• High-pressure cold spray (HPCS) used to spray high-strength metals and alloys with compressed gases like nitrogen, helium and air at high pressures (300-1000 psi)
• Low-pressure cold spray (LPCS): used to spray soft metals and metal/ceramic mixes with compressed gases at low pressures (below 300 psi).
