Method, Device and System for Active Cooling of Cold-Spray Nozzles
• Anti-clog cold spray nozzles
• Longer operating life of the cold spray nozzles, resulting in time and cost savings
• Compatible with commercial cold spray systems globally
• Adaptable to cold spray systems used for a variety of applications, such as dimensional restoration, wear- and corrosion-resistant coatings, and/or near net shaped parts
Cold Spray technology is a deposition process in which metal powder particles are accelerated by injection into a high-velocity stream of gas at temperatures below their melting point through a de Laval nozzle. However, clogging in the inside of the nozzle during the deposition process presents a significant challenge for this technology. This UMass Amherst invention provides a new method, device and system for active cooling of cold spray nozzles that can effectively prevent clogging and increase the operating life of the nozzles.
