Research in Toughening Wear-Resistant of Alumina Ceramic

Article Preview

Abstract:

This article describes the alumina ceramic mixed with two kinds of additives in order to improve the performance of ceramic, such as mixed with submicron ZrO2 and Nano-SiC. The main use of monoclinic zirconia (m-ZrO2) and tetragonal zirconia (t-ZrO2) of reversible phase transition of volume change and use of nano-SiC particle dispersion toughening mechanism to improve the toughness and wear resistance of composite alumina ceramic. Through doing various tests about fired products, including hardness testing, SEM test and bulk density measurement, we can understand the microstructure and mechanical properties of some of the products for analysis.
