Embodiment 1
[0041] Rare earth composite nanoparticles reinforced alumina ceramic material cutter head is obtained by mixing rare earth composite nanoparticles, alumina powder and silicon carbide powder, adding them to the mold for pressing, and finally sintering. The mass ratio of alumina powder and silicon carbide powder is 60 :30, the mass fraction of rare earth composite nanoparticles in the cutter head is 0.6%. The preparation method of rare earth composite nanoparticles is as follows: add cerium nitrate to nano zeolite powder-nano copper mixed particles, stir evenly, then add to the grinder, and then add tartaric acid, maleic acid, acrylamide to the grinder respectively , N, N'-methylenebisacrylamide, heated to 80 ° C, ground for 2 hours, and then dried to obtain a dry mixture, and then added the obtained dry mixture to a calciner for calcination treatment to obtain a rare earth composite nano particles. The mass ratio of the nano zeolite powder to the nano copper mixed particle in ...
