摘要：

The high-temperature oxidation of SiC–Al2O3–ZrO2 composite material in air under the action of concentrated solar radiation at temperature close to the melting point leads to the formation of a three-layer wear- and corrosion-resistant protective scale with an outer layer of aluminum silicate Al2SiO5 about 180 μm in depth with fine fibrous structure. It is shown that preliminary hightemperature oxidation of the composite improves its service characteristics.
