Sensors, such as the Coldspraymeter, allow us to validate numerical models (CFD) that can then be used to design cold spray nozzles that meet specific requirements in terms of particle velocity. Furthermore, they allow us to better understand the spray deposition windows of reactive materials to ensure that we avoid powder reaction during consolidation and also to maximize the reactivity of the consolidated powders.

The Coldspraymeter is the ideal tool for researchers and production managers involved in cold spray processes. It helps to validate fluid dynamic models, optimize spray nozzles, develop and optimize spray parameters, maximize deposit efficiency and monitor the process during production runs. Its intuitive touch screen user interface makes it easy to integrate into your daily operations. The data is available as CSV files and can be easily accessed via Ethernet or a USB jump drive.
