Abstract
Disclosed are an anti-corrosion and anti-coking ceramic coating with easy state identification for a coal-fired boiler and a preparation method thereof. The ceramic coating is formed by compounding a bottom coating layer and a surface coating layer, wherein the bottom coating layer is prepared from raw materials comprising sodium silicate, lanthanum oxide, niobium pentoxide, aluminum oxide, bismuth oxide, boron oxide, zinc oxide, silicon oxide, titanium dioxide, nano whisker, titanium nitride, and graphite fluoride, and the surface coating layer is prepared from raw materials comprising sodium silicate, lanthanum oxide, niobium pentoxide, chromium oxide, aluminum oxide, bismuth oxide, boron oxide, zinc oxide, silicon oxide, graphite fluoride, titanium nitride, silicon carbide, nano whisker, and cobalt green. An operating state of the ceramic coating is rapidly identified by a color difference between the bottom coating layer and the surface coating layer, which is beneficial to efficient maintenance of the ceramic coating during inspection.
