Izinto ze-Ceramic ziyizinto ezingaphili, ezingezona ezensimbi ezilungiselelwe isenzo sokushisa nokupholisa okulandelayo. Izinto ze-Ceramic zingase zibe ne-crystalline noma ingxenye ye-crystalline structure, noma zingase zibe i-amorphous (njengengilazi). I-ceramics evamile kakhulu i-crystalline. Umsebenzi wethu uphathelene kakhulu neTechnical Ceramics, eyaziwa nangokuthi i-Engineering Ceramic, Advanced Ceramic noma i-Special Ceramic. Izibonelo zokusetshenziswa kwe-ceramic yobuchwepheshe amathuluzi okusika, amabhola e-ceramic kuma-ball bearings, imibhobho yokushisa igesi, ukuvikelwa kwe-ballistic, ama-pellets e-nuclear fuel uranium oxide, izifakelo ze-bio-medical, ama-jet engine turbine blades, nama-missile nose cones. Izinto zokusetshenziswa ngokuvamile azifaki ubumba. Ngakolunye uhlangothi, ingilazi, nakuba ingabhekwa njenge-ceramic, isebenzisa ukucubungula okufanayo kanye nezindlela ezifanayo zokukhiqiza nokuhlola njenge-ceramic.

Ukusebenzisa umklamo othuthukisiwe kanye nesofthiwe yokulingisa kanye nempahla yelebhu yezinto ezinikezwa yi-AGS-Engineering:

• Ukuthuthukiswa kokwakhiwa kwe-ceramic

I-ceramics yobuchwepheshe ingahlukaniswa ngezigaba ezintathu ezihlukene zezinto ezibonakalayo:

• Ama-oxides: i-alumina, i-zirconia

• Ama-non-oxides: ama-carbides, ama-borides, ama-nitrides, ama-silicides

• Izinhlanganisela: Izinhlayiya eziqinisiwe, inhlanganisela yama-oxides nama-non-oxides.

 

Ngalinye lalawa makilasi lingathuthukisa izakhiwo zezinto ezibonakalayo ngenxa yokuthi i-ceramics ivame ukuba yikristalu. Izinto ze-Ceramic ziqinile futhi azisebenzi, ziyaphuka, ziqinile, ziqinile ekucindezelekeni, zibuthakathaka ekugundani nasekubambeni. Zimelana nokuguguleka kwamakhemikhali lapho zingaphansi kwemvelo ene-asidi noma ye-caustic. I-Ceramics ngokuvamile ingakwazi ukumelana namazinga okushisa aphezulu kakhulu asukela ku-1,000 °C kuya ku-1,600 °C (1,800 °F kuya ku-3,000 °F). Okuhlukile kufaka phakathi izinto ezingaphili ezingafaki umoya-mpilo njenge-silicon carbide noma i-silicon nitride.  Abantu abaningi abaqapheli ukuthi ukudala umkhiqizo ngezitsha zobumba ezithuthukisiwe kuwumsebenzi onzima odinga umsebenzi omningi kakhulu kunezinsimbi noma ama-polymer. Lonke uhlobo lwe-ceramic yobuchwepheshe lunezinto ezishisayo ezishisayo, zemishini, nezikagesi ezingahluka kakhulu kuye ngendawo okukuyo kanye nezimo ecutshungulwa ngaphansi kwazo. Ngisho nenqubo yokukhiqiza yohlobo olufanayo lwe-ceramic material yobuchwepheshe ingashintsha kakhulu izakhiwo zayo.

 

Ezinye izinhlelo zokusebenza ezidumile ze-ceramics:

​

I-Ceramics isetshenziswa ekwenzeni imimese yezimboni. Ama-blade emimese yobumba azohlala ecijile isikhathi eside kunaleyo yemibese yensimbi, nakuba intekenteke kakhulu futhi ingahlwithwa ngokuyiwisa endaweni eqinile. 

 

Kuma-motorports, uchungechunge lwezingubo zokuvikela ezihlala isikhathi eside nezingasindi sezidingekile, ngokwesibonelo kuma-nifold exhaust, ezenziwe ngezinto zobumba.

 

I-Ceramics efana ne-alumina ne-boron carbide isetshenziswe kumavesti ahlomile we-ballistic ukuxosha umlilo wesibhamu esikhulu. Amapuleti anjalo aziwa ngokuthi Ama-Small Arms Protective Inserts (SAPI). Izinto ezifanayo zisetshenziselwa ukuvikela ama-cockpits ezindiza ezithile zempi, ngenxa yesisindo esiphansi sempahla.

 

Amabhola e-Ceramic asetshenziswa kwamanye ama-ball bearings. Ubulukhuni bazo obuphakeme busho ukuthi akulula kakhulu ukugqokwa futhi banganikela isikhathi esingaphezu kokuphindwe kathathu. Ziphinde ziwohloke kancane ngaphansi komthwalo okusho ukuthi zinokuthintana okuncane nezindonga ezithwalayo futhi zingaginqika ngokushesha. Ezinhlelo zokusebenza zejubane eliphezulu kakhulu, ukushisa okuvela ku-friction ngesikhathi sokugoqa kungabangela izinkinga kuma-bearings ensimbi; izinkinga ezincishiswa ngokusetshenziswa kwezitsha zobumba. Ama-Ceramics nawo amelana kakhulu namakhemikhali futhi angasetshenziswa ezindaweni ezimanzi lapho ama-bearings ensimbi angagqwala khona. Izithiyo ezimbili ezinkulu zokusebenzisa izitsha zobumba yizindleko eziphakeme kakhulu, kanye nokuba sengozini yokulimala ngaphansi kwemithwalo eshaqisayo. Ezimweni eziningi izakhiwo zabo zokuvikela ugesi zingase zibe wusizo kumabheringi.

 

Izinto ze-Ceramic zingasetshenziswa futhi ezinjinini zezimoto namathuluzi okuthutha esikhathini esizayo. Izinjini ze-Ceramic zenziwe ngezinto ezilula futhi azidingi uhlelo lokupholisa, ngaleyo ndlela zivumela ukunciphisa okukhulu kwesisindo. Ukusebenza kahle kukaphethiloli kwenjini nakho kuphezulu emazingeni okushisa aphezulu, njengoba kuboniswa yithiyori kaCarnot. Njengobubi, enjinini yensimbi evamile, amandla amaningi akhishwa kuphethiloli kufanele ahlakazwe njengokushisa okulahlwayo ukuze kuvinjelwe ukuncibilika kwezingxenye zensimbi. Kodwa-ke, naphezu kwazo zonke lezi zakhiwo ezifiselekayo, izinjini ze-ceramic azikho ekukhiqizeni okubanzi ngoba ukukhiqizwa kwezingxenye ze-ceramic ngokunemba okudingekayo nokuqina kunzima. Ukungapheleli ezintweni ze-ceramic kuholela ekuqhekekeni, okungaholela ekuhlulekeni okungaba yingozi kwemishini. Izinjini ezinjalo ziye zaboniswa ngaphansi kwezilungiselelo zaselabhorethri, kodwa ukukhiqizwa ngobuningi akwenzeki okwamanje ngobuchwepheshe bamanje.

 

Kuqhutshwa umsebenzi wokuthuthukisa izingxenye ze-ceramic zezinjini ze-turbine yegesi. Njengamanje, ngisho nama-blade enziwe ngama-alloys ensimbi athuthukisiwe asetshenziswa esigabeni esishisayo sezinjini adinga ukupholisa futhi anciphise amazinga okushisa okusebenza ngokucophelela. Izinjini eziphehla ugesi ezenziwe ngezitsha zobumba zingasebenza kahle kakhulu, zinikeze izindiza ububanzi obuningi kanye nomthwalo wenani elimisiwe likaphethiloli.

 

Izinto zobumba ezithuthukisiwe zisetshenziselwa ukukhiqiza amakesi wewashi. Into esetshenziswayo ithandwa abasebenzisi ngesisindo sayo esilula, ukumelana nokuklwebheka, ukuqina, ukuthinta okubushelelezi kanye nokunethezeka emazingeni okushisa abandayo uma kuqhathaniswa namakesi ensimbi.

 

I-Bio-ceramics, njengokufakwa kwamazinyo namathambo okwenziwa kungenye indawo ethembisayo. I-Hydroxyapatite, ingxenye yamaminerali yemvelo yethambo, yenziwe ngokwenziwa kusuka emithonjeni eminingi yezinto eziphilayo namakhemikhali futhi ingakhiwa ibe yizinto zobumba. Izimila zamathambo ezenziwe ngalezi zinto ezisetshenziswayo zibopha kalula emathanjeni nakwezinye izicubu emzimbeni ngaphandle kokwenqatshwa noma ukusabela kokuvuvukala. Ngenxa yalokhu, banentshisekelo enkulu yokulethwa kwezakhi zofuzo kanye nezikafula zobunjiniyela bezicubu. Iningi le-ceramics ye-hydroxyapatite inezimbobo kakhulu futhi ayinawo amandla emishini ngakho-ke isetshenziselwa ukumboza izinsimbi zensimbi zamathambo ukuze zisize ekwakheni isibopho emathanjeni noma njengezigcwalisi zamathambo kuphela. Zibuye zisetshenziswe njengezigcwalisi zezikulufu zepulasitiki zamathambo ukusiza ekwehliseni ukuvuvukala nokwandisa ukumuncwa kwalezi zinto zepulasitiki. Ucwaningo luyaqhubeka ukuze kukhiqizwe izinto zobumba eziqinile futhi eziminyene kakhulu ze-nano-crystalline hydroxyapatite zemishini yokuthwala isisindo samathambo, esikhundleni sensimbi yangaphandle kanye nezinto zepulasitiki zamathambo nge-synthetic, kodwa ngokwemvelo, amaminerali amathambo. Ekugcineni lezi zinto zobumba zobumba zingase zisetshenziswe esikhundleni samathambo noma ngokuhlanganiswa kwama-collagen amaprotheni, angasetshenziswa njengamathambo okwenziwa.

 

I-Crystalline Ceramics

Izinto ze-ceramic ze-crystalline azikwazi ukusetshenziselwa uhla olukhulu lokucutshungulwa. Kunezindlela ezimbili ezijwayelekile zokucutshungulwa - beka i-ceramic esimweni oyifunayo, ngokuphendula endaweni, noma "ngokwenza" izimpushana zibe yisimo osifunayo, bese u-sintering ukwakha umzimba oqinile. Amasu okwakha i-Ceramic ahlanganisa ukubumba ngesandla (ngezinye izikhathi kufaka phakathi inqubo yokuzungeza ebizwa ngokuthi "ukuphonsa"), ukukhishwa kwe-slip, i-tape casting (esetshenziselwa ukwenza ama-capacitor e-ceramic amancane kakhulu, njll.), ukubumba umjovo, ukucindezela okomile, nokunye okuhlukile._cc781905-5cde -3194-bb3b-136bad5cf58d_ Ezinye izindlela zisebenzisa ingxubevange phakathi kwalezi zindlela ezimbili.

 

Izitsha ze-ceramics ezingezona i-crystalline

I-ceramics engeyona i-crystalline, eyizingilazi, yakhiwe ngokuncibilika. Ingilazi yakheka lapho incibilike ngokuphelele, ngokujikijelwa, noma lapho isesimweni sokubonakala kwethofi, ngezindlela ezinjengokuphephezela esikhunjeni. Uma ukwelashwa okushisayo kwakamuva kubangela ukuthi le ngilazi ibe yikristalu ngokwengxenye, into ewumphumela yaziwa ngokuthi i-glass-ceramic.
