Composites based on Al2O3 and ZrO2 are used. Coatings deposited by plasma spraying technology are studied with the use of X-ray diffraction and electron microscopy combined with electron diffraction methods. Phase transitions and specific coatings layered microstructure with local fluctuations of phase and chemical composition are connected with the conditions of plasma spray process.
