| description | Combination of alumina (Al2O3) and zirconia (ZrO2) as cutting tool have been established
themselves as a dominant in ceramic category for dry machining. The mechanical properties
of Al2O3-ZrO2 cutting tool were critically dependent on its density and hardness, which
affected by the powder preparation and sintering processes. This paper present the effect of
sintering temperature on density, hardness and tool wear of Al2O3-ZrO2 cutting tool. Specific
composition of 80-90 wt% Al2O3 and 10-20 wt% ZrO2 powders were mixed and ball milled
for 12 hours. These powders then were compacted in the form of RNGN120600 designated
cutting tool by using manual hydraulic press before undergone secondary compaction by
Cold Isostatic Press. The compacted powders then were sintered from 1200oC to 1400oC at
constant 9 hours soaking time. For each sintered cutting tool, evaluation has been made based
on the density and hardness. By using AISI 1045 as a workpiece material, the wear
performance of the selected cutting tools were evaluated within 200-350 m/min cutting
speeds, 0.1 mm/rev feed rate and 0.5 mm depth of cut. The results shows that the sintering
temperature at 1400oC and 9 hours soaking time produced maximum relative density and
hardness for 90 wt% Al2O3 and 10 wt% ZrO2 at 94.17% and 63.4 HRC respectively. Cutting
tool contained with 80 wt% Al2O3 and 20 wt% ZrO2 contributed maximum relative density
of 97% and hardness of 70.07 HRC. Maximum tool life recorded was 156s at 200 m/min
cutting speed. Wear mechanisms of fabricated cutting tool dominated by the notch and flank
wear at the early stage of machining and formation built up edge at the end of machining
process. |
