Novel wear-resistant ceramic material and preparation method thereof
The invention discloses a novel wear-resistant ceramic material and a preparation method thereof. The novel wear-resistant ceramic material consists of an upper surface layer, a middle layer and a lower surface layer, the upper surface layer is made of layered double hydroxides (LDHs), [M<2+>0.8N<3+>0.2(OH)2][(NO3<->)0.2.6H2O]; the middle layer is made of zirconium oxide; the material of the lowersurface layer is layered double hydroxides (LDHs), [M<2+>0.8N<3+>0.2(OH)2][(NO3<->)0.2.6H2O]; and M<2+> is one of Sr<2+>, Mg<2+> and Ni<2+>, and N<3+> is one of Al<3+>, Ga<3+> and Cr<3+>. The preparation method comprises the following steps: burdening, ball-milling and mixing, plasticizing and granulating, dry-pressing and forming, glue discharging and pressureless sintering. The novel wear-resistant ceramic material has excellent wear resistance, thermal fatigue resistance, antibacterial property, high strength and fracture toughness.
本发明公开了一种耐磨陶瓷新材料及其制备方法，其由上表面层、中间层、下表面层组成；上表面层材料为层状双金属氢氧化物(LDHs)，[M2+0.8N3+0.2(OH)2][(NO3‑)0.2·6H2O]；中间层材料为氧化锆；下表面层材料为层状双金属氢氧化物(LDHs)，[M2+0.8N3+0.2(OH)2][(NO3‑)0.2·6H2O]；其中，M2+为Sr2+、Mg2+和Ni2+中的一种，N3+为Al3+、Ga3+和Cr3+中的一种；其制备方法包括：配料，球磨混合，塑化造粒，干压成型，排胶，无压烧结。该耐磨陶瓷新材料具有优异的耐磨性、耐热疲劳性、抗菌性、高强度与断裂韧性。
