Abstract

The optical scattering characteristics of two kinds of the rough costing surface with different materials ZrO₂ 8Y₂O₃ and NiCrAlY applied the plasma-thermal spraying are studied in this paper. The micrographs with different magnification of the thermal sprayed coating surfaces have been taken by a scan electron microscope (SEM). In addition, the intensity distribution of the spatial scattering has also been gotten using an He-Ne laser beam to irradiate the rough surface of the plasma-sprayed coating and compared with others spatial scattering out of reflection spot of a smooth glass plane. The experiment results shown that different coating material and the plane have different scattering distribution in space and can use a laser system with Gauss-shaped which have different light spot diameter to project on the rough surface of the thermal sprayed coating to measure some parameters.
