Beschreibung
Zusammenfassung:	The invention discloses an aluminized protective coating as well as a preparation method and application thereof, and the preparation method comprises the following steps: step 1, spraying an inorganic fiber coating on the surface of a base material, and drying to form an inorganic fiber layer on the surface of the base material; the inorganic fiber coating comprises inorganic fibers, an organic binding agent and a dispersing agent. And step 2, carrying out aluminizing treatment on the base material treated in the step 1 and an aluminizing agent, and forming an aluminizing protective coating on the inorganic fiber layer. According to the preparation method, the inorganic fibers are mutually connected through the organic coupling agent, the inorganic fiber layer with the specific pore diameter is prepared on the surface of the base material after drying, the inorganic fiber layer can effectively inhibit the agglomeration effect of molten aluminum atoms in the subsequent aluminizing process, and then the obtain
