Fabrication and machining performance of ceramic cutting tool based on the Al2O3-ZrO2-Cr2O3 compositions
This study presents the cutting tool development of zirconia toughened alumina (ZTA) with chromia addition. The process used for its development is solid-state, in which the powders of Alumina (Al2O3), Zirconia (ZrO2) and Chromia (Cr2O3) were processed by a ball mill, com�pacted under a Cold Isost...

| description | This study presents the cutting tool development of zirconia toughened alumina (ZTA) with
chromia addition. The process used for its development is solid-state, in which the powders
of Alumina (Al2O3), Zirconia (ZrO2) and Chromia (Cr2O3) were processed by a ball mill, com�pacted under a Cold Isostatic Press (CIP) and sintered at a constant temperature of 1400 ◦C
with 9h soaking time. The initial study investigated the effect of Polyethylene glycol (PEG)
as a binder, CIP and hardness of Al2O3-ZrO2 mixtures. The percentage composition between
Al2O3 and ZrO2 was varied to choose the best for the highest mechanical performances
determined by the density, porosity and properties analysis. The cutting tool that possessed
the highest hardness and bending strength was selected the Al2O3-ZrO2 mixture was mixed
0.6 wt% Cr2O3 for machining trials within the cutting speed of 200–350m/min and constant
feed rate and depth of cut of 0.150mm/rev and 0.5mm, respectively. The results of the ZTA
mixed with Cr2O3 and combined with the ratio 80-20-0.6 wt% showed that the addition of
0.6 wt% PEG and a CIP pressure at 300 MPa and 60 s dwell time resulted maximum hardness
and bending strength of 71.03 HRc and 856.02 MPa, respectively. The fabricated cutting tool
was capable to reach 225 s tool life when machining AISI 1045 at a lower cutting speed of
200 m/min and higher feed rate of 0.150mm/rev. |
