This paper summarizes what are the measuring techniques used in plasma spraying to characterize
- plasma jets and their fluctuations: emission spectroscopy, laser scattering spectroscopy, enthalpy probes coupled to mass spectroscopy and fast cameras,
- particles in flight in plasma jets: laser doppler anemometry. Phase Doppler Anemometry, fast two-color pyrometry, laser fluxmetry, hot particles light emission...
- particles at impact: fast pyrometry and fast cameras,
- substrate and coating temperature: IR pyrometry and IR thermography.
The new set-ups to achieve an on-line control, on more precisely a monitoring of the spray process are also presented: DPV2000, Accuraspray, Plumespector, Spray watch, CCD cameras, SDC.
