Semiconductor ukoresheje ibikoresho byirabura alumina ceramic ukuboko

Ibisobanuro bigufi:

Kurwanya kwambara kwa alumina ceramics ni kimwe na corundum, igera kuri Mohs igoye kurwego rwa 9, kandi kwihanganira kwambara byagereranywa nubwa superhard alloys. Kurwanya ubushyuhe bwa alumina ceramics bifite ibiranga coefficient ntoya yo kwagura ubushyuhe, imbaraga za mashini nyinshi hamwe nubushuhe bwiza. Muri icyo gihe, alumina ikoreshwa cyane mu bice bya mashini bikoreshwa mu gihe cy'ubushyuhe bwinshi kubera imikorere y’ubushyuhe bwo hejuru (kugeza 1700 ℃).

Alumina ceramics

1. Gukomera cyane

Gukomera kwa Rockwell ni HRA80-90, ubukana buri munsi ya diyama, birenze kure kwihanganira kwambara ibyuma bidashobora kwangirika ndetse nicyuma.

2. Kurwanya kwambara neza

Upimye n'ibigo by'ubushakashatsi bw'umwuga, kwihanganira kwambara bihwanye ninshuro 266 z'ibyuma bya manganese. Gaoming cast Iron inshuro 171.5, dukurikije imyaka irenga icumi dukurikirana ubushakashatsi bwabakiriya, mubihe bimwe byakazi, birashobora kongera igihe cyibikorwa byibikoresho byibuze inshuro icumi.

3. Uburemere bworoshye

Ubucucike bwa 3.5g / cm3 ni kimwe cya kabiri cyicyuma, gishobora kugabanya cyane imitwaro yibikoresho.
