Special features of synthesis of a heat-resistant glass-ceramic coating

In order to protect Ni-Cr alloys from high-temperature corrosion, a new heat-resistant glass-ceramic coating was developed with a glass matrix synthesised on the basis of a RxO-Al2O3-SiO2-TiO2 (R = Li+, Na+, K+, Mg2+, Ca2+, Ba2+) system. The formation of crystalline phases in the glasses during heat...

Zusammenfassung:	In order to protect Ni-Cr alloys from high-temperature corrosion, a new heat-resistant glass-ceramic coating was developed with a glass matrix synthesised on the basis of a RxO-Al2O3-SiO2-TiO2 (R = Li+, Na+, K+, Mg2+, Ca2+, Ba2+) system. The formation of crystalline phases in the glasses during heat treatment and the optimum regime for the formation of a glass-ceramic structure are described. The desirable phases crystallise in glasses containing Li2O3 and TiO2 in a 1:1 ratio. The size of the microcrystalline particles formed is 1-3 micron.
