DEVELOPMENT OF COMPOSITE COATINGS
Keywords:
Nanocomposite metal-ceramic materials (cermets), metal reduction, computer modeling, solar furnace synthesis, X-ray phase analysis, selective absorption coatings, spectral-optical properties, blackness level, selectivity coefficient, heat resistance, vacuum heat sink.Abstract
Currently, the technology of converting solar energy into heat is well developed, mature and economically competitive.This project uses a quasi-metallurgical method of partial reduction of metals from oxides using solid carbon in a solar furnace to synthesize cermet composite materials. This allows obtaining metal nanoparticles directly from matrix oxides. By changing the carbon concentration, temperature and process time, the concentration of metal nanoparticles and the conditions of the reduction reaction can be changed.
