Intonga yeCeramic yeZirconia enamandla aphezulu – yeeShafts kunye neePunches ezichanekileyo
Intonga yeseramikhi ye-zirconia yaseSt.Cera igutyungelwe ngokuchanekileyo kwi-yttria-stabilized ZrO₂. Inika amandla angaqhelekanga okugoba (1000 MPa), ukuqina kokuqhekeka (5–8 MPa·m¹/²), kunye nobunzima beVickers (13 GPa). Intonga inembonakalo emnyama okanye emhlophe, ubuninzi be-6.03 g/cm³, kwaye ayinazo iimbobo. Ububanzi ukusuka kwi-1 mm ukuya kwi-50 mm, ubude ukuya kwi-200 mm, kunye nokunyamezela okuqinileyo njenge-±0.005 mm. Ukugqitywa komphezulu kudibene ne-Ra ≤0.2 μm. Ifanelekile kwizicelo ezigugileyo ezifana nee-plunger, ii-shafts, ii-dowel pins, kunye nee-cutting tool blanks.
Iinkcukacha (ezisekelwe kwi-Y-TZP ZrO₂):

Izicelo:
- · Ii-plunger kunye neepiston ezichanekileyo
- · Izikhonkwane zeDowel zokulungelelanisa
- · Ukusika izikhewu zezixhobo (iimela, iziqwenga)
- · Iirola ezithwala iibheringi kwiindawo ezirhabaxa
Iingenelo:
- · Ayisebenzisi magnethi, ikhusela ubushushu ngombane (>10¹³ Ω·mm²/m)
- · Iyamelana neekhemikhali ezirhabaxa (ii-asidi, ii-alkali ngaphandle kwe-HF)
- · Akukho mhlwa okanye ukurhawuzelela
Ukuvelisa:
Izikhewu zentonga ezisikiweyo → ukugaya ngaphandle kwesiseko ukuya kububanzi obuchanekileyo → ukugoba/ukupholisha → ukucoca nge-ultrasonic. Ukuhlolwa kobubanzi obuyi-100% nge-laser micrometer.
