[0038] The present invention also provides a preparation method of the high-temperature corrosion-resistant coating described in the above technical solution, comprising the following steps:
[0039] (1) mixing ceramic powder and metal powder, and carrying out high-energy ball milling to obtain cermet powder;
[0040] (2) mixing chromium, nickel and the cermet powder obtained in the step (1) to obtain a high-temperature corrosion-resistant coating.
[0041] The invention mixes the ceramic powder and the metal and performs high-energy ball milling to obtain the cermet powder. The present invention has no special requirements on the method of mixing the ceramic powder and the metal, and the material mixing method well known to those skilled in the art can be used. In an embodiment of the present invention, the mixing of the ceramic powder and the metal is specifically stirring and mixing; the rotation speed of the stirring and mixing is preferably 100-300r / min, more preferably ...
