Paper Abstract

The light spot images on the coating rough surface with the plasma-thermal sprayed coating materials ZrO28Y2O3 and NiCrAlY when the laser beam (visible, wavelength is 632.8 nm, power is 2 mw) with different diameter shined on it have been studied and its experimental demonstration has also been presented in this paper. The Charge Coupled Device camera is applied to detect the light spot image field distribution, and 3D distribution of the light spot images have been obtained by computer. Above experiment results give us some basis knowledge to measure the coating thickness in the next step, which shows the physical behavior of the light spot. In addition, the different profiles of Gauss laser spot image on the rough surface for ZrO28Y2O3 and NiCrAlY coating have been analyzed.
