Impact-resistant ceramic for thermal spraying and preparation method of impact-resistant ceramic
The invention discloses an impact-resistant ceramic for thermal spraying. The impact-resistant ceramic is prepared from the following raw material components in parts by weight: 16-20 parts of aluminum oxide, 20-24 parts of titanium carbide, 10-16 parts of red stoneware mud, 26-30 parts of zirconium oxide, 3-5 parts of zirconium phosphate, 2.5-4.5 parts of boron nitride, 1-3 parts of manganese dioxide, 2-4 parts of carbon fibers, 4-6 parts of triethanolamine, 2-4 parts of anhydrous sodium sulphate, 3-5 parts of silicon sol, 1.5-2.5 parts of calcium formate, 1-2 parts of hydroxy methyl cellulose, 1-2 parts of lignin sulfonate, 3-5 parts of paraffin wax, 1-3 parts of rare-earth compound powder and a proper amount of deionized water, wherein the rare-earth compound powder comprises the following components in percentage by weight: 31%-33% of La, 24%-39% of Eu, 20%-26% of Sc, 9%-11% of Gd and 9%-12% of Sm; and the sum of the components is 100%. The ceramic disclosed by the invention is fine and hard in texture, and has extremely high hardness and abrasive resistance; by virtue of the added carbon fibers, the tenacity and abrasive resistance are increased; by virtue of the added zirconia, the heat resistance and abrasive resistance of the ceramic can be increased; and a coating prepared from the ceramic is good in crack resistance and long in service life.
