Using Al2O3-Mgo-PSZ ceramic system in cutting tools manufacturing

Engineering and Technology Journal, 2009, Volume 27, Issue 7, Pages 250-257

Recent advance in high-speed cutting materials have focused on reinforcing
alumina with different carbides and nitrides in order to improve hardness and fracture
toughness, this composites materials use in cutting tools application. The present study
concert on properties of cutting tools made by Al2O3 reinforcement by Mg-PsZ. The
added weight fractions from ZrO2 are (15% , 20%). The materials cold-pressed at (5, 7,
10) ton, at (1400, 1500, 1600 Co) in two hours. The result shows increasing in hardness
and densities values of specimen with the increasing the mixing percent also, there is a
signification enhancement of specimen properties with increased temperature and
pressure, the approperte temperature is 1600 Co with pressure 10 ton.
