The need for online spray diagnostics

In the mid ‘80s, the thermal spray community recognized that in order to bring thermal spray processes to the next level, there was a need for sensors able to provide real-time, in-flight particle information, right before impingement on the part. During thermal spraying, the particles become so hot they emit IR radiation, which is used to actually “see” and characterize (temperature, velocity, size, flux, trajectory) the particles. But with Coldspray, the particles are too cold (below 1,000° Celsius) to be detected by conventional pyrometric techniques. As a result, light is shone on them so they can be viewed by scattered light. In other words: we work with light reflection rather than light emission. In the last two decades, several diagnostic devices have been developed—both in research facilities and on the shop floor.
What can online spray diagnostics do for you?

Save time
Faster spray parameter development
Faster spray equipment optimization
Less test coupons required
Easy parameter transfer—from booth to booth or between spray facilities

Save money
Spray accurately the first time and minimize coating stripping
Optimize powder usage and minimize post-machining (spray to desired thickness, not more)
Optimize and control Deposit Efficiency (DE)

Ensure high-quality, reproducible coatings via:
Daily monitoring
Real-time comparisons of sprayed material properties with pre-determined acceptance ranges
Pre-programmed alarm triggering
Advanced shop floor monitoring
In a typical thermal spray booth, several variables and parameters have a direct impact on coating properties, so controlling them in a production environment is critical to obtaining the desired final results. The Accuraspray G3C gives you process-independent control of coating properties based on non-contact measurement of intrinsic material characteristics, right before impingement on the part. What’s more, it’s reliable, rugged, easy to set up and easy to use.

Thermal spray R&D
The thermal spray research community uses the DPV sensor extensively to understand fundamental processes and for modelling and development. Our DPV, recognized as the industry standard, is the basis of over 600 scientific papers and, after all these years, it is still the only instrument that can simultaneously measure the temperature, velocity, size and flux of an individual particle.
