title = "Characterization of nonmelted particles in plasma-sprayed Al 2O3 coatings by scanning electron microscopy, Raman analysis and X-ray diffraction analysis",
abstract = "Plasma-sprayed ceramic coatings are deposited by flattened splats together with some nonmelted particles. In this study, the nonmelted particles in plasma-sprayed alumina coating were examined by scanning electron microscopy, confocal Raman analysis and X-ray diffraction analysis to aim at the quantitative evaluation of coating microstructure. Results showed that the nonmelted particles can be clearly identified from the cross-sectional microstructure due to the empaistic morphology resulting from the high hardness of the nonmelted particles. The obvious gap at the interface between nonmelted particles and the surrounding splats suggests the weak interface bonding. Raman analysis revealed that there was little α-Al2O3 phase in the flattened splats region, which confirms that α-Al 2O3 phase in the coating originates only from nonmelted particles. Moreover, it is proposed that the attention should be paied to the weak bonding of the nonmelted particles to flattened splats during the preparation of samples for the quantitative characterization of coating microstructure.",
