Polycrystalline Al2O3 alumina ceramics yihariye ubushyuhe bwo hejuru bwo kwambara

Ibisobanuro bigufi:

Alumina ceramics (Al203) nibikoresho byokwirinda kwambara neza bikoreshwa cyane mubikorwa bitandukanye. Uburyo nyamukuru bwo kubumba ibicuruzwa bya alumina ceramic ni ugukanda byumye, gukanda isostatike, gutera inshinge no guteramo, nibindi. Imiterere yibicuruzwa bitandukanye, ingano nibisobanuro bisaba uburyo butandukanye bwo kubumba. Nyuma yubushyuhe bwo hejuru bwibicuruzwa bya alumina ceramic, gusa inzira yo gusya diyama irashobora gutunganywa. Ubuziranenge bwibisanzwe bya alumina ni 90% -99.9%.

Ibicuruzwa

Imikorere ya aluminium oxyde ceramics

1 - Gukomera hejuru

Ubukomezi bwa Rockwell bwibumba bya alumina ni HRA80-90, icya kabiri nyuma ya diyama mubukomere, birenze kure ibyuma bidashobora kwangirika no kwangirika kwicyuma.

2 - Kwambara neza

Imyambarire yo kwambara ya alumina ceramics ihwanye ninshuro 266 zicyuma cya manganese ninshuro 171.5 zicyuma kinini cya chromium. Mubihe bimwe byakazi, birashobora kongera igihe cyibikorwa byibikoresho byibuze inshuro icumi.

3 - Uburemere bworoshye

Ubucucike bwibumba bya alumina ni 3,7 ~ 3.95g / cm °, ni kimwe cya kabiri cyicyuma nicyuma, kandi birashobora kugabanya cyane imitwaro yibikoresho.

4 - Urwego runini rwo gusaba

Ububiko bwa Alumina bukoreshwa cyane mumashini, fibre optique, ibikoresho byo gukata, ubuvuzi, ibiryo, imiti, ikirere nizindi nzego.

Ibyiza bya alumina ceramics:

1 - Ububiko bwa Alumina bufite ibintu byiza cyane. Igihombo kinini cyane ni gito, kandi kwihuta cyane ni byiza.

2 - Ububiko bwa Alumina bufite imbaraga zo kurwanya ubushyuhe, coefficient ntoya yo kwagura ubushyuhe, imbaraga za mashini nyinshi hamwe nubushuhe bwiza.

3 - Ububiko bwa Alumina bufite imiti irwanya imiti kandi irwanya ibyuma bishongeshejwe.

4 - Ububiko bwa Alumina ntabwo bwaka, ntabwo bworoshye kubora kandi bukomeye kandi ntabwo byoroshye kwangirika, hamwe nibindi bikoresho kama nibikoresho byuma ntibishobora kugereranwa nubwiza buhebuje.

5 - Alumina ceramics isumba iyindi kwambara, gukomera hamwe na corundum kimwe, irashobora kugera kuri Mohs gukomera 9, imyambarire yayo irashobora guhuzwa nudukoko twinshi cyane.
