Abstract

Three zirconia ceramics, ZrO_2-4.5mol%Y_2O_3, ZrO_2-12mol%Y_2O_3, and ZrO_2-8mol%MgO, before and after plasma spraying were investigated by X-ray diffraction. The amounts of monoclinic, tetragonal and cubic phases existing in the three zirconia ceramics were determined from the integrated intensity ratios in the {400} and {111} regions of the X-ray diffraction patterns. Tetragonal-to-monoclinic transformation in the plasma-sprayed coatings caused by indentation, fracture and/or heat treatment of laser beam was examined by Raman spectroscopy. As a result, this spectroscopic technique is shown to be a powerful tool for the observation of this transformation. Furthermore, microanalysis of the coatings was performed by the use of Raman microprobe spectroscopy.
