Document Type and Number:
WIPO Patent Application WO/2022/057518
Kind Code:
A1
Abstract:
Provided is the use of a glass composite material with a high softening point, a low thermal expansion coefficient, a high wear resistance and a low thermal conductivity in an engine gas turbine. The glass composite material comprises glass powder particles and filling powder particles, wherein the filling powder particles are ceramic powder particles, natural mineral powder particles or metal powder particles, the glass powder particles are sintered to bond and wrap the ceramic powder particles, the natural mineral powder particles or the metal powder particles, and the softening temperature of the glass composite material is＞850℃. The glass composite material provided in the present invention has the eight advantages of a high strength performance in a high-temperature state, a temperature change performance of adapting to rapid cooling and heating, a low thermal expansion performance, a low thermal conductivity of less than 9 w/[(m.K)], an ultrahigh strength performance, a high softening point (deformation point), a high wear resistance and a high hardness performance.
