Technological specifics of devitrified composite heat-resistant coatings for nichrome alloys

Compositions are developed, technological parameters are determined, and the main properties are investigated for devitrified glass composite heat-resistant coatings of the R x O - Al2O3 - SiO2 - TiO2 system (R is Na+, K+, Mg2+, Ca2+, Ba2+) for Nichrome alloys.
