High Performance Cold Spray Process Development

PolyCSAM is a new industrial-scale cold spray additive manufacturing (CSAM) facility created by Polycontrols to address production and industrialization challenges. It serves as a demonstrator and an innovation/development platform. A recent strengths, weaknesses, opportunities, and threats (SWOT) analysis revealed that the supply chain is solid and diversified for all key components, with the exception of the cold spray (CS) gun itself. There is a clear business opportunity for Polycontrols to come up with innovations that have the potential to be disruptive in the world of CS additive manufacturing. The objective of this project is to develop a new high-performance CS gun that exploits the potential innovations in the following areas: recurrent nozzle clogging, nozzle designs maximizing particle’s impact velocity & temperature, coating internal diameters, and efficient powder preheating. Specific activities that will develop new innovative solutions to allow for the production of a new gun that reaches a technology readiness level of 5 will be performed using CFD and modern engineering design tools.
