| 简介 |
FIELD : technological processes.
SUBSTANCE : invention relates to production of heat-resistant materials and can be used for application of high-temperature antioxidative protective coatings on high-heat-resistant structural materials (carbon-carbon and carbon-ceramic composite materials, coal graphite materials, alloys based on Nb, Mo, W) widely used in aerospace, rocket and other industries. Proposed material for heat-resistant protective coating contains the following, wt% : titanium 35.0–40.0, molybdenum 8.0–10.0, boron 8.0–10.0, calcium 1.5–3.0, at least one element from the group of rare-earth metals (REM) 0.2–0.8, silicon – the rest. Material has a heterophase structure, mainly titanium diboride (TiB2), titanium and molybdenum disilicide of variable composition (TixMo1-xSi2, 0.1
