Synthesis and Properties of Heat Resistant Coatings Based on a Si–B4C–ZrB2–ZrO2 Composition

This article discusses the influence of nanosized particles of zirconium dioxide on the properties of a heat-resistant coating synthesized by the suspension annealing of a silicon–boron carbide–zirconium diboride composition. The heat resistance of coatings on graphite and high silica ceramic substrates is studied, and the phase composition, morphology, hardness, and electric resistance of the coatings are determined.
