(I-Hip Si3n4 BallKukhiqizwa nguI-WintrustEK)

I-SINTERING iyinqubo lapho izinto eziyimpuphu zihlanganiswa futhi zifudunyezwa ukwakha inqwaba eqinile. Imvamisa, inqubo yenzeka ngaphansi kwamaphuzu 'ancibilikiyo okuncibilika. Izinhlayiya zilethwa ukusondela ngesikhathi senqubo yesono, futhi uhlelo lokusebenza lokushisa luthuthukisa ukubopha ama-athomu kanye nokufakwa phakathi kwezinhlayiya, okuholela ekunciphiseni nasekwakhiweni kwesakhiwo esiqinile. Izinsimbi, ama-composites, nama-ceramics avame ukukhiqizwa yi-sonse.

Inqubo eyaziwa ngokuthi "ukushisa okushisayo ngokugcwele," noma "okhalweni," kusetshenziselwa ukuthuthukisa izimfanelo zokwenziwa kanye nobuqotho bezinto zokwakha. Ifaka phakathi kanye nokusebenzisa ingcindezi ephezulu kanye nokushisa okubonakalayo. Enqubweni ye-hip, igesi e-inert isetshenziselwa ukucindezela impahla efudumele ekushiseni okumiselwe kusengaphambili ngaphakathi komkhumbi wengcindezi. Ingcindezi ephezulu kanye nokushisa isebenza ngokubambisana ukususa amaphutha angaphakathi ekukhokhisweni, njengama-pores noma ama-voids, futhi aqinise izinsiza ze-powder metlugy ezingxenyeni eziminyene ngokuphelele.

I-Pinter ngaphansi kwengcindezi (i-hip: Ukucindezela okushisayo okushisayo, ama-SPS Ngenxa yalokhu, kungenzeka ukufeza amanani wokuhlaziya aseduze nobunzima bethiyori ngenkathi kuthuthukisa ukulawula ngokwengeziwe ngokwengeziwe kwe-ceramics.

Okuyisisekelo kwengcindezi esostatic
Ukufaka ingcindezi ngokwezinto ezibonakalayo ngasikhathi sinye kusuka kuzo zonke izinkomba kuyaziwa njengokucindezela okuzayo. Lokhu kwenziwa ngokubeka into esikhwameni noma esitsheni esivaliwe futhi kusetshenziswe ingcindezi ephezulu kusetshenziswa i-fluid medium, imvamisa igesi i-inert efana ne-argon. I-Anisotropy namaphutha mancane amathuba okuba ingcindezi isetshenziswa ngokufana njengoba lokhu kuqinisekisa ukuthi lokho okuqukethwe kuthambekile ngokufana.

Izimiso zokucindezela okushisayo okushisayo
Inqubo yokukhiqiza ebizwa ngokuthi i-Hot Isstatic Presping (HIP) isebenzisa ingcindezi ephezulu kanye namazinga okushisa ngokungaguquki kuzo zonke izinkomba eziya ezintweni zokwakha, ikakhulukazi ama-ceramics athuthukile. Ukukhiqizwa kwama-ceramics okusebenza okuphezulu ngempahla ethuthukisiwe yemishini, eshisayo, kanye nezakhiwo zikagesi, le ndlela ibalulekile.

Izinqubo zokucindezela okushisayo okushisayo:

Ukwakheka komzimba okuluhlaza → umzimba oluhlaza obebekwe egumbini elivaliwe → inqubo yokushisa elilawulayo → Ukucindezela okuzayo

I-Wintrustek yakhiqiza izingxenye eziningi ze-HIPN4, lapha, ikakhulukazi thina siphoqa lapho kwethulwaI-Hip Si3n4 Ball.

Ukucindezela okushisayo okushisayoziphakathi kwezindlela ezithuthuke kakhulu zokukhiqiza izinto ze-silicon nitride. Kuyaphawuleka ukuthi amandla ayo okusebenza kumasethingi anokhahlo lapho izinto zendabuko zingasebenzi. Ngenxa yesakhiwo sayo esishukumisayo esihle kakhulu, singamelana nokushaqeka kwe-thermal futhi sihlale sizinzile ebusweni bokushintsha izinga lokushisa okusheshayo. Ngoba kungeyona eyezibuthe futhi ayisebenzi, ingasetshenziswa ngemishini kagesi ebucayi noma yezokwelapha, futhi i-coeffliction yayo ephansi iqinisekisa ukusebenza okubushelelezi ezinhlelweni ezijikelezayo ezisheshayo. Le bhola le-ceramic lithembekile ukuthi isetshenziswa ezinhlelweni ze-vacuum, ezivezwa kumakhemikhali, noma zigijime ngaphandle kokuthambisa.

Izinzuzo ze-Hip Si3n4 Amabhola:

• Ukugqoka okungahambisani

• Isisindo esikhanyayo,

• Ukufakwa kukagesi

• Amandla acindezelayo aphezulu.

• Ukuncishiswa okuphezulu. Ukuxazulula ingaphezulu noma izici zangaphakathi, ikakhulukazi i-poronguty, khona-ke, singathola umphumela omuhle wokubekwa uphawu.

• Ubunzima obuphakeme. Izinto ze-ceramic zingenagazi. Ngobunzima obuphakeme, lapho bethukile ngokulambisa, imifantu kanye nezinkinga kuzokwenzeka. Singasho ukuthi ubunzima obuphakeme bungakugwema ukwehluleka okulimazayo.

Ngamafuphi, Ukucindezela okushisayo okushisayo kuyindlela eshintsha umdlalo emkhakheni we-Ceramic ukucubungula okuvula amathuba amasha ezicelo ze-ceramic ezinhlobonhlobo zezimboni futhi unikeza indlela eya ezimfanelweni ezingcono ezibonakalayo. Ukuze wakhe ubumba ubuciko obunelisa izidingo zokusebenza okuphezulu, inqubo ye-hip ilawula kahle izinga lokushisa, ingcindezi, nesikhathi nesikhathi. Ibamba iqhaza elibalulekile ekwakhiweni kwezinto zokwenziwa kwe-ceramic kanye nokusetshenziswa kwazo emasimini abalulekile. Ngokuqondene namabhola we-hip, ngesidingo sejubane eliphezulu, ukugcwala kwamahhala, anti-elementi, kanye nezinye izindawo zohlelo lokusebenza, zidlala ngokuncika nokuphepha okuhlukile.
