Fibrous nanocorundum products for use in a high-temperature gas flow
Results are presented from a study of the structure and kinetics of formation of a protective nano-inoculated coating on a fibrous substrate. The article examines the erosion resistance of the materials at 1600 – 1800°C in a gasdynamic unit with electric-arc heating (in an aerodynamic system with a sectional plasmotron). The gaseous medium consisted of products of the combustion of kerosene in air. Flow velocity ranged up to 100 m/sec.
