Nanometer mixed powder, high-temperature antioxidant coating and application of nanometer mixed powder and high-temperature antioxidant coating
The invention discloses nanometer mixed powder, a high-temperature antioxidant coating and application of the nanometer mixed powder and the high-temperature antioxidant coating, and belongs to the technical field of steel heat treatment antioxidant protection. The high-temperature antioxidant coating comprises the nanometer mixed powder, and the nanometer mixed powder comprises, by weight, 50%-75% of silicon nitride nano-powder, 10%-25% of active carbide, 10%-15% of an accelerant and 5%-10% of an agglutinant, wherein the active carbide is selected from SiC powder, B4C powder and Al4C3 powder, the accelerant comprises SiO2, Al2O3 and K2O+Na2O, and the agglutinant comprises Fe3O4. By means of the high-temperature antioxidant coating, steel metal has the good antioxidant performance during high-temperature heat treatment, the application scope is wider, and the pollution to the environment is small, and the cost is low.
