;EXPERIMENTAL 2.1 Fabrication of polymer-coated ceramic powder Powder with average grain size of 0.2μm, and purity of 99.99% for Al2O3 was used. Both ZrO2 and TiC were 99.99% pure and the grain size was about 0.5μm. The composite powder was milled for 36h in media containing high-purity Al2O3 balls and pure ethyalcohol. After cleaned and dried, the composite ceramic powder was added into 4......
