Friction and wear analysis of ceramic cutting tool made from Alumina-Zirconia-Chromia
This research focused on the friction and wear analysis of ceramic cutting tool made from Al2O3, ZrO2 and Cr2O3. 80 wt% of Al2O3 and 20 wt% of ZrO2 compacts were prepared by ball milling process with Cr2O3 addition at the variation of 0.2, 0.4, 0.6 and 0.8 wt%. Each sample was pressed by C...

| description | This research focused on the friction and wear analysis of
ceramic cutting tool made from Al2O3, ZrO2 and Cr2O3.
80 wt% of Al2O3 and 20 wt% of ZrO2 compacts were
prepared by ball milling process with Cr2O3 addition at
the variation of 0.2, 0.4, 0.6 and 0.8 wt%. Each sample was
pressed by Cold Isostatic Press at 350 MPa before sintered
at the constant temperature of 1400oC and 9 hours
soaking time. Relative density, hardness, flexural strength
and Pin-on-disc tribotest were performed for each sample.
The samples with desired mechanical properties were
further machined with AISI 1045 at the cutting speed of
200 m/min, 0.175 mm/rev feed rate and 0.5 mm depth of
cut. The results show the sample with composition ratio of
Al2O3-ZrO2-Cr2O3 at 80-20-0.6 wt% demonstrated
lowest Coefficient of Friction (COF) of 0.23 with hardness
and relative density recorded at 71.3 Hrc and 95.81%
respectively. Microstructure of Al2O3-ZrO2-Cr2O3
presenting significant grains compaction as compared to
Al2O3-ZrO2 and single Al2O3 that showed significant
appearance of porosity. In terms of tool wear, Al2O3-
ZrO2-Cr2O3 performed 51% and 800% better tool life
than Al2O3-ZrO2 and Al2O3 cutting tools. |
