Izindaba

Uma ungumuntu osebenzisa insimbi, uyazi ukuthi amaphutha afana nokuvuleka, ukufakwa, noma imifantu angabiza kangakanani.Izihlungi ze-Ceramic Foam (CFF) akuzona nje “izihlungi”—ziyithuluzi elibalulekile lokuhlanza insimbi encibilikisiwe, ukuthuthukisa ubuqotho bokubumba, nokunciphisa imfucuza yokukhiqiza. Kodwa zisetshenziselwani ngempela? Ake sihlukanise izinhlelo zazo ezibalulekile ngokwemboni kanye nohlobo lwensimbi, ukuze ubone ukuthi zihambisana kanjani nomsebenzi wakho.

1. Ukuphonswa Kwensimbi Okungeyona Insimbi: Yenza Ukuphonswa Kwe-Aluminium, Ithusi, Ne-Zinc Kungabi Naphutha

Izinsimbi ezingezona i-ferrous (i-aluminium, ithusi, i-zinc, i-magnesium) zisetshenziswa kabanzi ezimotweni, kuma-elekthronikhi, kanye nakumapayipi—kodwa ukuncibilika kwazo kuthambekele ekufakweni kwe-oxide kanye nama-gas bubbles. Izihlungi ze-Ceramic Foam zilungisa lokhu ngokubamba ukungcola ngaphambi kokuba zifike esikhumbeni.

Ukusetshenziswa Okuyinhloko Lapha:

Ukwenziwa kwe-Aluminium Casting (indlela enkulu yokusetshenziswa engeyona i-ferrous):

Izihlungi zisusa ama-oxide e-Al₂O₃ kanye nemfucumfucu emincane ku-aluminium encibilikisiwe, okuqinisekisa ukuthi i-castings ibushelelezi futhi iqinile. Ilungele:

Izingxenye zezimoto:Amasondo, amabhlogo enjini, izindawo zokufaka amagiya (amaphutha ambalwa asho impilo yengxenye ende).

Izingxenye zezindiza:Ama-alloy e-aluminium alula ozimele bezindiza (adinga insimbi emsulwa kakhulu).

Izimpahla zabathengi:Izitsha zokupheka ze-aluminium, amabhokisi e-laptop (akukho zinkinga ebusweni).

Ukubunjwa Kwethusi Nethusi:

Ibamba izinto ezifakwe ku-sulfide kanye nezingcezu eziphikisayo, ivimbela ukuvuza ku:

Izingxenye zokufaka amapayipi:Amavalvu, izinto zokufaka, amapayipi (okubalulekile ekusebenzeni okungangeni manzi).

Izingxenye zikagesi:Izixhumi zethusi, amatheminali (ithusi elimsulwa liqinisekisa ukuhanjiswa kahle kwegesi).

Ukuphonswa kwe-Zinc kanye ne-Magnesium:

Izihlungi zilawula ukwakheka kwe-oxide ku-high-pressure die casting (HPDC) ye:

Izinto zikagesi:Amakesi efoni e-zinc alloy, ozimele be-laptop ye-magnesium (izindonga ezincane azidingi zinkinga).

Ihadiwe:Izibambo zeminyango ye-zinc, izingxenye zamathuluzi kagesi e-magnesium (ikhwalithi ehambisanayo).

2. Ukuphonswa Kwensimbi Enensimbi: Insimbi Elungisiwe, Ukuphonswa Kwensimbi Okusetshenziswa Ngomthwalo Onzima

Izinsimbi zensimbi (insimbi, insimbi ephonswe) zibhekana nokucindezeleka okuphezulu—kodwa ukuncibilika kwazo okushisa okuphezulu (1500°C+) kudinga izihlungi eziqinile. Izihlungi ze-Ceramic Foam lapha zivimba i-slag, izingcezu ze-graphite, kanye nama-oxide awonakalisa amandla.

Ukusetshenziswa Okuyinhloko Lapha:

Ukwenziwa Kwensimbi Nensimbi Engagqwali:

Imelana nokuncibilika kwensimbi eshisayo ukuze ikhiqize izingxenye ezithembekile:

Imishini yezimboni:Amavalvu ensimbi, imizimba yephampu, amabhokisi egiya (akukho mifantu yangaphakathi = isikhathi esincane sokungasebenzi).

Ukwakhiwa:Amabhuleki esakhiwo sensimbi engagqwali, izixhumi ze-rebar (zimelana nokugqwala).

Imishini yezokwelapha:Amathuluzi okuhlinza ensimbi engagqwali, izinki zasesibhedlela (insimbi emsulwa = ukusetshenziswa okuphephile).

Ukulingisa Ngensimbi:

Kuthuthukisa isakhiwo se-microstructure:

Izimoto:Ama-disc e-brake ensimbi ampunga, ama-crankshaft ensimbi athambile (aphatha ukungqubuzana kanye ne-torque).

Imishini esindayo:Izingxenye zetrakta yensimbi ephothiwe, imihlathi yokuqhekeza (idinga ukumelana nokuguguleka).

Amapayipi:Amapayipi amanzi ensimbi ampunga (akukho ukuvuza okuvela ekufakweni).

3. Ukuphonswa Okukhethekile Okunezinga Eliphezulu Lokushisa: I-Tackle Titanium, Ama-Alloys Ane-Refractory

Ngezicelo ezisezingeni eliphezulu (isikhala sezindiza, i-nuclear), lapho izinsimbi zishisa kakhulu (1800°C+) noma zisabela (titanium), izihlungi ezijwayelekile ziyahluleka. Izihlungi ze-Ceramic Foam (ikakhulukazi ezisekelwe ku-ZrO₂) yizona kuphela ezisetshenziswayo.

Ukusetshenziswa Okuyinhloko Lapha:

Ukuphonswa kwe-Titanium Alloy:

Ukuncibilika kwe-titanium kuthintana nezinto eziningi—kodwa izihlungi ze-ZrO₂ zihlala zingasebenzi, okwenza:

Izingxenye zezindiza:Ama-blade enjini ye-titanium, igiya lokufika lendiza (lidinga insimbi emsulwa kakhulu ukuze liphakame kakhulu).

Izimila zezokwelapha:Ukufakwa esikhundleni kwe-titanium hip, izitho zamazinyo (akukho ukungcola = okuhambisana ne-biocompatible).

Ukuphonswa kwe-Alloy Refractory:

Ihlunga ama-superalloy angewona awe-ferrous (asekelwe ku-nickel, asekelwe ku-cobalt) ukuze:

Ukukhiqizwa kwamandla:Izingxenye ze-turbine yegesi ye-nickel-alloy (iphatha ukukhishwa kwe-1000°C+).

Imboni yenuzi:I-Zirconium alloy fuel cladding (imelana nemisebe kanye namazinga okushisa aphezulu).

Kungani Izihlungi Ze-Ceramic Foam Zinqoba Ezinye Izinketho?

Ngokungafani ne-wire mesh noma izihlungi zesihlabathi, ama-CFF:

Inesakhiwo esinezimbobo ze-3D (ibamba ukungcola okuningi, ngisho nokuncane).

Imelana namazinga okushisa aphezulu (1200–2200°C, kuye ngokuthi isetshenziswa kanjani).

Sebenza nazo zonke izinsimbi ezinkulu (i-aluminium kuya ku-titanium).

Nciphisa amazinga okulahla ngo-30-50% (wonga isikhathi nemali).

Thola i-CFF Efanele Yecala Lakho Lokusebenzisa

Kungakhathaliseki ukuthi uphonsa izingxenye ze-auto ze-aluminium, ama-valve ensimbi engagqwali, noma ama-implant e-titanium, sinezihlungi ze-Ceramic Foam ezenzelwe izidingo zakho. Izihlungi zethu zihlangabezana nezindinganiso ze-ISO/ASTM, futhi ithimba lethu likusiza ukuthi ukhethe izinto ezifanele (i-Al₂O₃ ye-aluminium, i-SiC yensimbi, i-ZrO₂ ye-titanium).

Xhumana nathi namuhla ukuthola isampula yamahhala kanye nesilinganiso esenziwe ngokwezifiso. Yeka ukulwa namaphutha okukhipha—qala ukwenza izingxenye ezingenaphutha nge-CFF!
