Ibumba rya alumina rya polycrystalline Al2O3 rishobora kwangirika mu bushyuhe bwinshi

Imikorere ya ceramics ya aluminiyumu okiside

1--Ubukomere buri hejuru

Ubukomere bwa alumina ceramics bwa Rockwell ni HRA80-90, ni ubwa kabiri nyuma ya diyama mu bukomere, buruta kure cyane icyuma kidashira n'icyuma kidashira.

2--Ubudahangarwa Bwiza bwo Kwambara

Ubudahangarwa bw'icyuma cya alumina burangana n'inshuro 266 z'icyuma cya manganese n'inshuro 171.5 z'icyuma cya chromium nyinshi. Mu gihe kimwe cyo gukora, gishobora kongera igihe cyo gukora cy'ibikoresho byibuze inshuro icumi.

3--Uburemere bworoheje

Ubucucike bwa alumina ceramics ni 3.7 ~ 3.95g / cm°, ni ukuvuga kimwe cya kabiri cy'icyuma n'icyuma, kandi bishobora kugabanya cyane umutwaro w'ibikoresho.

4--Ikoreshwa ryagutse

Ibumba rya alumina rikoreshwa cyane mu mashini, fibre optique, ibikoresho byo gukata, ubuvuzi, ibiribwa, imiti, ikirere n'ibindi.

Ibyiza by'ibibumbano bya alumina:

1--Ibumba rya alumina rifite ubushobozi bwiza bwo kwirinda ubushyuhe. Gutakaza ubushyuhe bwinshi ni bike, kandi ubushyuhe bwinshi ni bwiza.

2--Ibumba rya alumina rifite ubushobozi bwo kwirinda ubushyuhe, ubushobozi bwo kwaguka k'ubushyuhe buke, imbaraga nyinshi za mekanike n'ubushobozi bwiza bwo gutwara ubushyuhe.

3--Ibumba rya alumina rifite ubushobozi bwo kudakoresha imiti n'ubudakoresha icyuma gishongeshejwe.

4--Ibumba rya alumina ntirishobora gushya, ntiryoroshye kuringiza kandi rirakomeye kandi ntiryoroshye kwangiza, hamwe n'ibindi bikoresho by'umwimerere n'ibikoresho by'icyuma ntabwo bishobora kugereranywa n'ubwiza bwiza.

5--Izi ceramic za alumina zirwanya kwangirika cyane, ubukana na corundum ni bimwe, zishobora kugera ku bukana bwa Mohs 9, ubukana bwazo bushobora guhuzwa n'ibyuma bikomeye cyane.
