Momwe mungapangire machubu a ng'anjo ya silicon carbide?

Momwe mungapangiremachubu a ng'anjo ya silicon carbide?Choyamba, tiyenera kutsimikizira zimenezosilicon carbidendiye zinthu zazikulu zopangira, ndipo silicon carbide imapangidwa pambuyo pa kutentha kwambiri.Zomwe zapezedwa zimakhala ndi kukana kutentha kwambiri, kuthamanga kwamafuta othamanga, kulimba kwamphamvu, kulimba kwambiri, kukana kuvala bwino, kukana kugwedezeka kwamafuta, kuwongolera kwamafuta abwino, kukana kwa okosijeni ndi ntchito zina zabwino kwambiri.

Kamodzi okonzeka ndi wapadera mkulu kutentha kutchinjiriza chivundikiro chapamwamba-mapeto, kupewa zitsulo njira dzimbiri za magetsi Kutentha element, potero kuteteza magetsi Kutentha amafotokozera.Zizindikiro zake zosiyanasiyana ndizabwino kuposa mamachubu a ng'anjo ya silicon carbideza zinthu zosiyanasiyana za graphite, ndipo zimakhala ndi matenthedwe abwino komanso kukana kwa okosijeni.Ndi kusintha njira kupanga zirconia zochokera electrolyte filimu, akatswiri kuchepetsa kutentha ntchito ndi kupanga mtengo wa zipangizo zimenezi, ndi kuyesetsa kukwaniritsa mafakitale, amenenso n'kofunika latsopano malangizo kwa pakachitsulo carbide m'tsogolo.Mapangidwe apamwamba a ionic, kukhazikika kwamankhwala abwino komanso kukhazikika kwamapangidwe a zirconia ceramics adaphunziridwa bwino ndikugwiritsidwa ntchito kwambiri ngati zida za electrolyte.

The katundu ndi sintering njira zamachubu a ng'anjo ya silicon carbideamayambitsidwa.Silicon carbide ng'anjo chubu sikuti imakhala ndi mawonekedwe amphamvu ya kutentha kwambiri komanso kukana kukwawa.Kukana kuvala, mphamvu ya kutentha kwa chipinda, coefficient yotsika ya kukangana, kukana kwa dzimbiri.Itha kugwira ntchito pa kutentha kwa 1600 ndipo imadziwika kuti ili ndi kukana kwa okosijeni pazinthuzo.Silicon carbide ng'anjo chubu ali ndi kuipa kwa mkulu brittleness ndi otsika fracture kulimba.Popanga pambuyo pake, kulimba ndi mphamvu zimatha kupitilizidwa powonjezera ulusi, ndevu ndi tinthu.

Silicon carbide ndi chinthu chabwino kwambiri cholimbana ndi dzimbiri, titha kuchigwiritsa ntchito popanga machubu ang'anjo ndi zinthu zina.Pamene silicon carbide ntchito kupanga machubu ng'anjo, pali njira zosiyanasiyana sintering monga moto otsika, kutentha thupi, chatsekedwa kupanga, amene akhoza kusankhidwa malinga ndi malo processing kwenikweni kusintha dzuwa.Kukanikiza kotentha komanso kutentha kwambiri kwa isostatic kumatha kubweretsa kachulukidwe kwambirisilicon carbide ng'anjo chubu, kutentha kwapakati pa 150 ~ 2100℃.Silicon carbide ndizovuta kupanga mawonekedwe ovuta komanso zinthu zotsika mtengo.Silicon carbide reaction sintering ndi silicon ndi graphite ufa mu gawo lina la wobiriwira wobiriwira kuti apange -SiC.Njirayi imapanga silicon carbide yokhala ndi kutentha kochepa.Komabe, ena mwa silicon yaulere amakhalabe mu billet wobiriwira, kotero wopanga zingwe amakhulupirira kuti izi zimachepetsa kutentha kwamphamvu kwamakina ndikugwiritsa ntchito kwake mu ma acid amphamvu ndi maziko.

Ponena za kayendedwe ka ng'anjo ya ng'anjo ya silicon carbide, pambuyo popanga chubu cha ng'anjo ya silicon carbide, ngati imasamutsidwa kunja kwa ndondomekoyi, sichinthu choposa vuto lowononga kwambiri.Kodi umphumphu wake ungatsimikiziridwe bwanji kuchokera kumalo otere?Chubu chopangidwa ndi silicon carbide ng'anjo chimayikidwa mu chubu chakumapeto kwa mbale yopingasa, ndipo chubu cha ng'anjo chimakhazikika polumikizana ndi tepi yomangira ndi chomangira.Gwirizanitsani chomangira chochotsedwa ku cholumikizira china.Chidutswa chokonzekera kumapeto kwenikweni kwa chingwe chimagwirizanitsidwa ndi groove yokhazikika yomwe imayikidwa pamwamba pa mbale yotsutsana, ndipo pulley imakwezedwa kumtunda woyenera kupyolera mu ntchito yosinthira.Kumapeto kwa bokosi lamagetsi la ndodo yotsekera kumachotsedwa, ndipo ndodo ya slide imadutsa mulumikizidwe, ndipo mbale yotsutsana nayo imayikidwa pa mzati, yomwe imagwira ntchito yotumiza machubu ambiri a ng'anjo, ndipo kuyendetsa bwino kumawonjezeka ndi kawiri.Mwanjira iyi, ntchitoyo ndi yabwino, magulu angapo a mbale zopirira amakhazikitsidwa, ndipo machubu ang'anjo amatha kuikidwa pogwiritsa ntchito chubu chokhazikika pa mbale yopirira, zomwe zimapangitsa kuti machubu ang'anjo azikhala bwino komanso kuchuluka kwa ng'anjo. ng'anjo machubu.Pad yosasunthika yomwe imatha kuyikidwa mu chubu groove imagwiritsidwa ntchito kuteteza chubu la ng'anjo.
