HEAT-RESISTANT NON-FIRED REPAIR COATINGS FOR PROTECTION OF CARBON-BASE MATERIALS
ABSTRACT
The method for generating heat-resistant protective coatings of silicide type by non-fired technology is presented. The binder of the slip suspension was a nanodispersed silica sol, and the fillers were powders of the previously developed materials of the Si−TiSi2−MoSi2−B−Y and Si−TiSi2−MoSi2−B−Y−SiC systems. Such coatings are designed to protect heat-resistant carbon-base materials (carbon−carbon composite materials (CCCM) and carbon−ceramic matrix composites (CCMC), structural graphite) against high-temperature gas corrosion. This method allows one to minimize the problems encountered when it is necessary to protect the connecting units of the prefabricated structural elements, inter alia, elements of high dimensions (wing edges, protective screens, casings, etc.), as well as to solve problems related to repair of various damages of standard coatings that are inevitable during the assembly and/or operation of the space-rocket hardware.
