Kugadziriswa kweceramic silicon carbide - Maitiro, mashandisirwo uye marudzi

Precision machined sintered silicon carbide zvikamu zvakagadziriswa neSingapore Fountyl Technologies PTE Ltd., Mune zvese zvinoshandiswa zvinoda yakakwirira-chaiyo einjiniya zvikamu, zvakakosha kuziva kuoma kwekugadzirisa silicon carbide. Pasinei nekuoma kwayo kwepamusoro kukosha, ichiri chinhu chisina kusimba chinogona kugadziriswa chete uchishandisa madhaimani ekukuya. saka, machining mashandiro nevashandisi vane hunyanzvi uye vane ruzivo vanobatsira, sezvo nzira dzisina kunaka dzinogona kugadzira kukuvadzwa kwepasi uye micro-cracks iyo inogona kukonzeresa kukundikana nguva isati yakwana kana chikamu chiri pasi pekushanda kunetseka mukushandiswa.

Synthetic silicon carbide:

Kazhinji, silicon carbide inogadzirwa uchishandisa iyo Acheson process, iyo inosanganisira kupisa silica jecha uye kabhoni kune yakanyanya kupisa muvira reAcheson graphite resistance. Inogona kuumba hupfu hwakatsetseka kana zvisungo zvakasungirirwa uye inofanira kupwanywa nekukuyiwa isati yashandiswa sehupfu. Kana iyo silicon carbide yave muhupfu, tsanga dzekomboni dzinogona kusunganidzwa pamwe chete nekunyungudika kuti dziumbe ainjiniya anobatsira kwazvo ane huwandu hwakasiyana hwekushandisa mumaindasitiri mazhinji ekugadzira.

Mhando dzesilicon carbide:

Silicon carbide zvigadzirwa zvekutengesa engineering zvikumbiro zvinogadzirwa mumhando nhatu. Izvi ndezvi:

Sintered Silicon Carbide (SSC)

Nitride yakasungirirwa silicon carbide (NBSC) uye

Reactive bonded silicon Carbide (RBSC)

Zvimwe zvakasiyana-siyana zvekomboni zvinosanganisira ivhu-bonded silicon carbide uye SiAlon-bonded silicon carbide. Kune zvakare kemikari mhute yakaiswa silicon carbide inonzi CVD silicon carbide, iri chimiro chakanyanya kuchena chekomboni.

Kuti uite sinter silicon carbide, zvinodikanwa kuwedzera sintering agent, iyo inobatsira kuumba chikamu chemvura pane sintering tembiricha, nekudaro ichisunga silicon carbide tsanga pamwechete.

Kushandiswa kukuru kwesilicon carbide:

Silicon carbide ine zvakawanda zvinoshandiswa mumaindasitiri akasiyana. Kuoma kwayo kwemuviri kunoita kuti ive yakanaka kune abrasive processing yekugaya, honing, sandblasting uye waterjet kucheka.

Silicon carbide inogona kumira zvakanyanya tembiricha isingatyoke kana kukanganisa uye inoshandiswa kugadzira ceramic brake discs emotokari dzemitambo. Iyo inoshandiswawo mumabhururu evhavha sechinhu chezvombo uye chisimbiso chemhete chekuvhara pombi shaft zvisimbiso, uko inowanzoshanda nekumhanya kwakanyanya kana ichisangana neyakafanana silicon carbide seals. Imwe yemabhenefiti makuru ezvishandiso izvi ndeyekupisa kwekushisa kwesilicon carbide, iyo inokwanisa kudzima kupisa kwefriction kunogadzirwa neiyo friction interface.

Iko kuoma kwepamusoro kwechinyorwa kunobvumira kuti ishandiswe mune akawanda einjiniya maapplication ayo anoda yakakwira dhigirii yekutsvedza, kukukurwa, uye kupfeka kwekuora. Kazhinji izvi zvinogona kushandiswa kune zvikamu zvinoshandiswa mumapombi, kana semuenzaniso mavharuvhu mune oirifield application, uko echinyakare simbi zvikamu zvinogona kuratidza yakawandisa kupfeka mitengo, zvichikonzera kukundikana nekukurumidza.

Komboni yacho ine yakasarudzika magetsi emagetsi semiconductor, ichiita kuti ive yakakodzera kugadzira ekupedzisira-nekukurumidza uye akakwira-voltage light-emitting diodes, MOSFETs, uye thyristors epamusoro-simba switch.

Izvo zvinhu zvine yakaderera coefficient yekuwedzera kwemafuta, kuomarara, kusimba uye kupisa conductivity, zvichiita kuti ive yakanakira girazi zvinhu kune zvemuchadenga teresikopu. Silicon carbide fibers, inonzi filaments, inoshandiswa kuyera kupisa kwegasi uchishandisa nzira yekuona inonzi filament pyrometry.

Iyo inoshandiswawo pakudziya zvinhu zvinoda kuchinjirwa kune yakanyanya kupisa tembiricha. Inotoshandiswa musimba renyukireya kupa tsigiro yezvimiro zvemaayakita anodziya gasi-anotonhodzwa.
