Experimental Studies on Laser Space Scatting of Plasma-thermal Sprayed Coating with Materials for ZrO28Y2O3 and NiCrAlY2

WT5BZ]The space scattering field of the radiant laser on the rough surface for the materials both ZrO 28Y 2O 3 and NiCrAlY of the plasma thermal sprayed coatings (metal basis) are studied in this paper. The light source is an He Ne laser with power 2mW and wave length is 633.0 nm. The space scattering fields with different scattering angles and different space positions are obtained using an array CCD (charge coupled device) sensor when the laser illuminated up the experiment sample with different incident angles directly. The experiment results show that different scattering angle have different space scattering distribution. This provide the experimental base for further measurement on the industry parameters of the thermal sprayed coatings such as coating thickness and surface pattern employing optical method.
