The Coldspray Meter is an ideal tool to:
The Coldspray Meter uses photo-optical sensors to detect individual particles in the spray plume. The in-flight particles passing through the detectors generate a signal used to accurately determine velocity, size and feed rate for individual particles in the plume.
With acquisition rates as high as 300 particles per second, the Coldspray Meter is one of the most sensitive cold spray sensors in the industry today.
Individual particle detection generates histograms for particle velocity, size and feed rate in real-time. As displayed in the figure, particle distributions can become a powerful tool for modelling and process control. The histograms can be viewed with a volumetric scale on the x-axis to inform on deposition efficiency of the process.
Using the particle distributions generated by the Coldspray Meter, strong correlations can be identified between the parameters being measured. For example, particle velocities can be measured as a function of particle size and feed rate allowing in-depth process learning, monitoring and control.
The Coldspray Meter comes with an X-Y scanning device to perform plume cross-sectional analysis. The scanner produces contour plots indicating the distribution of various particles in the plume cross-section, as shown in the figure. This unique feature offers great insight about plume dynamics in cold spray.
