High-temperature composite materials and coatings on the basis of glass and ceramics for aerospace technics

Abstract

High-temperature composite materials and coatings developed in the RIAM, specifically construction composite materials with glass, glass-ceramic, and ceramic matrices, for use at 700–1500°C, ceramic composites on the basis of poly-carbosilanes, erosion resistant coatings with the effect of thermal control for heat shield systems of perspective aerospace technics, are reviewed. These coatings combine a complex of properties: high radiating capacity, phase stability, thermal shrinkage resistance, resistance against acoustic, vibration, atmospheric factors, etc. Technological coatings to protect steels and Ti and Ni alloys during heat treatment and isothermal and hot die forging are developed. New type enamels, pasts, thick-film electric heaters, etc., are described.
