$Al_2O_3/SiC$ 나노복합체의 상압소결 및 역학적 특성에 미치는 볼밀분쇄와 소결온도의 영향

The Effect of Ball Milling and Sintering Temperatures on the Sintering Behaviors and Mechanical Properties of $Al_2O_3/SiC$ Nanocomposites


Al2O3/SiC nanocomposites are fabricated through intensive ball milling to mix fine SiC particles uniformly with the Al2O3 powder. Another role of milling is to reduce particle sizes by crushing particles as well as agglomerates. However, balls are worn during ball milling and the sample powder mixtures pick up to weight loss of the balls. In this study, pressureless sintering was performed to obtain Al2O3/SiC nanocomposites. It was found that the wear rate of zirconia balls during milling was considerable, and the zirconia addition after even a few hours of ball milling could increase the sintering rates of the nanocomposites significantly. Thus, addition of ZrO2 changed the sintering behaviors as well as mechanical properties of Al2O3/SiC nanocomposites.
