Xalka Premie Zirconia Ceramic Solutions ee Codsiyada Warshadaha Sare ee Dulmarka Marka laga hadlayo injineernimada agabka horumarsan, saxnaanta iyo adkeysiga ayaa muhiim ah. Taxaneheenna Barafka adag ee Zirconia wuxuu matalaa meesha ugu sarreysa tignoolajiyada dhoobada, oo loogu talagalay in lagu daboolo baahiyaha adag ee codsiyada warshadaha casriga ah. Qaybahan waxaa laga sameeyay agabka saafiga ah ee sare ee zirconia, hubinta xoog farsamo oo gaar ah, xasilloonida kulaylka, iyo caabbinta kiimikada. Haddii aad u baahan tahay dhululubo darajada wershadaha ee zirconia mashiinada culus ama qayb sax ah oo loogu talagalay aaladaha caafimaadka, alaabadayadu waxay bixiyaan waxqabad aan la mid ahayn. Sifooyinka gaarka ah ee zirconia, oo ay ku jiraan adkaanteeda sare ee jabka iyo xirashada iska caabbinta, waxay ka dhigtaa doorasho ku habboon deegaanka halkaas oo biraha dhaqameed iyo dhoobada kale ay gaaban yihiin. Sharaxaadda badeecadan oo dhammaystiran waxay qeexaysaa tayada sare ee bixinta dhoobada zirconia, taasoo muujinaysa isku-kalsoonidooda iyo isku hallaynta qaybaha kala duwan. Adiga oo dooranaya xalalka nadiifinta sare ee zirconia bar, warshaduhu waxay kor u qaadi karaan hufnaanta hawlgalka, yareeyaan kharashaadka dayactirka, iyo hubinta daacadnimada qaybta muddada dheer. Astaamaha Muhiimka ah Ururintayada adag ee Zirconia waxaa lagu farsameeyay habab wax soo saar oo casri ah oo dammaanad qaadaya tayada iyo waxqabadka joogtada ah. Dabeecad qeexan oo ka mid ah alaabooyinkan ayaa ah adkeysigooda gaarka ah, kaas oo si weyn uga sarreeya Alloys-macdan badan, taasoo bixisa iska caabin heersare ah oo ku saabsan xaaladaha abrasive. Maaddadu waxay soo bandhigaysaa iska caabbinta daxalka oo aad u fiican, taasoo ka dhigaysa mid ku habboon soo-gaadhista kiimikooyinka adag iyo bay'adaha aashitada iyada oo aan hoos u dhicin. Intaa waxaa dheer, kuleylka hooseeya ee zirconia waxay u oggolaaneysaa kuleylka kuleylka wax ku oolka ah, ka ilaalinta qaybaha xasaasiga ah ee kuleylka aadka u daran. Xoogga sare ee dabacsanaanta ee dhululubada darajada warshadaha ee zirconia waxay hubisaa daacadnimada qaabdhismeedka ee culeysyo culus, ka hortagga jebinta iyo fidinta nolosha adeegga. Intaa waxaa dheer, isqabqabsiga noole ee zirconia wuxuu ka dhigayaa wax la door bidayo in lagu rakibo caafimaadka iyo codsiyada ilkaha. Dhammaystirka dusha sare ee nadiifka sare ee zirconia bar waxay yaraynaysaa is jiid jiid waxayna yaraynaysaa halista abuuritaanka walxaha, taas oo muhiim u ah deegaanka qolka nadiifka ah. Astaamahani waxay si wadajir ah gacan uga geystaan adkaynta iyo cimri dhererka alaabtayada dhoobada ah, iyagoo siinaya xal kharash-ku-ool ah oo dalbanaya caqabadaha warshadaha. Sharaxaad faahfaahsan Aasaaska khadka alaabadayadu waxay ku jirtaa xulashada habboon ee alaabta ceeriin. Waxaan isticmaalnaa kaliya budada oksijiinta ugu sareysa ee zirconium dioxide, oo lagu farsameeyay farsamooyin horumarsan si loo gaaro qaab-dhismeed cufan oo isku mid ah. Nidaamkani wuxuu keenayaa Bar adag oo Zirconia ah oo leh porosity ugu yar, kor u qaadida sifooyinkeeda makaanikada iyo iska caabinta diiqada deegaanka. Habka wax soo saarka ayaa ku lug leh xakamaynta saxda ah ee heerkulka iyo cadaadiska, hubinta in qayb kasta ay la kulanto dulqaadyada adag ee cabbirka. Kala duwanaanshahayaga Sare ee Saafinimada Sare ee Zirconia Bar ayaa lagu heli karaa darajooyin kala duwan, oo ku habboon shuruudaha codsiyada gaarka ah. Tusaale ahaan, 3Y-TZP (Saddex-Yttria Stabilized Tetragonal Zirconia Polycrystal) waxay bixisaa adkeysi heer sare ah, halka 8Y-PSZ (Siddeed-Yttria Qayb ahaan xasiloon Zirconia) ay bixiso iska caabbinta shoogga kulaylka oo la xoojiyay. Dhululubo kasta oo heer warshadeed ah oo zirconia ah ayaa mara kormeero tayo leh oo adag, oo ay ku jiraan xaqiijinta cabbirka, falanqaynta qallafsanaanta dusha, iyo tijaabinta farsamada. Tani waxay hubinaysaa in qayb kasta oo la geeyo macaamiisheena ay u hoggaansamaan heerarka caalamiga ah ee ugu sarreeya. Kala-duwanaanta dhoobada zirconia waxay u oggolaanaysaa is-beddelka qaabka, cabbirka, iyo qeexidda, oo daboolaya baahiyaha gaarka ah ee warshadaha kala duwan. Laga soo bilaabo joomatari adag ilaa foomamka cylindrical ee fudud, kooxdayada injineernimada waxay si dhow ula shaqeeyaan macaamiisha si ay u horumariyaan xalal aan la garanayn oo kor u qaadaya waxqabadka iyo shaqeynta. Xasiloonida dabiiciga ah ee zirconia waxay hubisaa in qaybahani ay ilaashadaan hantidooda waqti ka dib, xitaa marka ay ku jiraan heerkulka isbeddelka iyo cadaadiska. Kalsoonidaani waxay muhiim u tahay codsiyada halka guuldarradu aysan ahayn ikhtiyaar, sida hawada hawada, baabuurta, iyo soosaarka semiconductor. Marka la maalgaliyo alaabadayada Zirconia Solid Bar, ganacsiyadu waxay ka faa'iidaysan karaan sayniska agabka horumarsan ee ka dambeeya zirconia si loo gaadho natiijooyin hawleed heersare ah. Muuqaallada Isticmaalka Codsiyada Barka Adag ee Zirconia iyo alaabada la xidhiidha waa kuwo aad u ballaaran oo kala duwan, oo ku baahsan warshado badan oo teknoolojiyad sare ah. Dhinaca caafimaadka, biocompatibility iyo xidhashada iska caabbinta zirconia waxay ka dhigtaa wax ku habboon taajka ilkaha, buundooyinka, iyo beddelka wadajirka miskaha. Soo jiidashada bilicda leh ee zirconia cad waxay sidoo kale gacan ka geysataa caannimada dhakhtarka ilkaha ee qurxinta. Warshadaha baabuurta, qaybaha zirconia waxaa loo isticmaalaa dareemayaasha oksijiinta, kuwa shidaalka lagu shubo, iyo qaybaha matoorada sababtoo ah degganaanshahooda kulaylka iyo sifooyinka korantada. Waxqabadka ayaa ka sarreeya kan Alumina Ceramic & Nadiifinta Sare ee Alumina Ceramic.
Waxqabadku kama hooseeyo kan dhoobada Zirconia & Aluminium Nitride ceramic.
