Embodiment 1
[0020] Weigh respectively 60% perhydropolysilazane and 20% graphite powder by volume, add them in turn to 20% butyl acetate, grind for 1 hour with a planetary ball mill, and then mechanically Stir with a mixer for 1 hour, then filter and encapsulate the paint sprayed as a transition layer. Then weigh the organopolysilazane, the barium glass powder of 30%, the zirconia powder of 15% and the aluminum powder of 5% respectively by volume percentage, add successively the butyl acetate of 30% by volume After being ground by a planetary ball mill for 1 hour, stirred by a mechanical stirrer for 1 hour, the coating sprayed as an organic polysilazane precursor composite ceramic coating was filtered and encapsulated.
[0021] The coating preparation process is as follows: first, the surface of the alloy steel substrate on the heating surface is pretreated by sandblasting; then the prepared transition layer coating is sprayed on the surface of the substrate, and placed in a heating furnac...
Embodiment 2
[0023] Weigh respectively 70% perhydropolysilazane and 15% graphite powder by volume, add them in turn to 15% butyl acetate, grind for 1 hour with a planetary ball mill, and then mechanically Stir with a mixer for 1 hour, then filter and encapsulate the paint sprayed as a transition layer. Then weigh the organopolysilazane, the barium glass powder of 25%, the zirconia powder of 20% and the aluminum powder of 10% respectively by volume percentage, add successively the butyl acetate of 20% by volume After being ground by a planetary ball mill for 1 hour, stirred by a mechanical stirrer for 1 hour, the coating sprayed as an organic polysilazane precursor composite ceramic coating was filtered and encapsulated.
[0024] The coating preparation process is consistent with Example 1.
Embodiment 3
[0026] Weigh respectively 60% perhydropolysilazane and 20% graphite powder by volume, add them in turn to 20% butyl acetate, grind for 1 hour with a planetary ball mill, and then mechanically Stir with a mixer for 1 hour, then filter and encapsulate the paint sprayed as a transition layer. Then weigh the organopolysilazane, the barium glass powder of 25%, the zirconia powder of 20% and the aluminum powder of 5% respectively by volume percentage, add successively the butyl acetate of 25% by volume After being ground by a planetary ball mill for 1 hour, stirred by a mechanical stirrer for 1 hour, the coating sprayed as an organic polysilazane precursor composite ceramic coating was filtered and encapsulated.
[0027] The coating preparation process is consistent with Example 1.
