Two-layer high temperature coating on a ceramic substrate, and process for obtaining same |
摘要 |
The high temperature coating for the protection of ceramic materials, in particular porous ones, from erosion and chemical and/or mechanical failure according to the invention comprises a barrier (primer) layer and an emissivity glaze (topcoat) layer, with the following weight compositions: barrier layer:"-" silicon tetraboride (with over 96 weight % of SiB4): 0.1 to 10%; quartz glass: 90 to 99.9%; emissivity glaze layer: silicon tetraboride (with over 96 weight % of SiB4): 1.5 to 5.0%; high silica glass: 95 to 98.5%.
