YSZ ceramic-based self-lubricating composite material as well as preparation method and application thereof
The invention discloses a YSZ (Yttria Stabilized Zirconia) ceramic-based self-lubricating composite material as well as a preparation method and application thereof, and relates to the technical field of self-lubricating ceramic materials. The composite material is prepared from the following raw materials: YSZ (Yttria Stabilized Zirconia), graphene and BN powder coated with SiO2; sintering the mixed powder at the temperature of 1250-1350 DEG C by utilizing a spark plasma sintering technology under the pressure of 30-50MPa, so as to obtain blocky composite ceramic; and 3) carrying out tribological performance test on the fired ceramic at 25-500 DEG C. According to the invention, the graphene and SiO2 coated BN powder are added into the YSZ, so that the tribological performance of the YSZ ceramic at 25-500 DEG C is improved.
本发明公开了一种YSZ陶瓷基自润滑复合材料及其制备方法和应用，涉及自润滑陶瓷材料技术领域。所述复合材料原料包括YSZ，以及石墨烯和SiO2包覆的BN粉末；所述粉末在30~50MPa的压力下，利用放电等离子烧结技术在1250~1350℃对混合粉末进行烧结，得到块状复合陶瓷；3）对烧制出的陶瓷进行25~500℃摩擦学性能测试。本发明通过在YSZ中添加石墨烯和SiO2包覆BN粉末，提高了YSZ陶瓷在25~500℃的摩擦学性能。
