Ezweni le-metrology ephezulu kanye nokulinganiswa kokunemba, ukuphishekela ukulinganisa okungenaphutha kuwuhambo oluqhubekayo. Njengoba izimboni ezifana nezindiza, i-semiconductor lithography, kanye nokukhiqizwa kwamadivayisi ezokwelapha kucindezela imingcele yalokho okungenzeka esikalini se-nanometer, amathuluzi asetshenziswa ukuqinisekisa lezi zilinganiso kumele aguquke. Ngenkathi i-granite nensimbi kuye kwasebenza njengezindinganiso zendabuko zamathuluzi okubhekisela, umholi omusha uvele ezindaweni ezidinga kakhulu: i-ceramics yobuchwepheshe esebenza kahle kakhulu. Izikwele ze-ceramic ezinembile kakhulu kanye nemiphetho eqondile ngokushesha ziba ukukhetha okuthandwayo kwamalabhorethri e-metrology angenakukwazi ukuyekethisa ekunembileni.
Ukushintshela ezintweni zobumba kuqhutshwa yisidingo esiyisisekelo sokuqina esidlula imingcele yemvelo yamatshe emvelo kanye nezinsimbi zensimbi. Ukuze uqonde ukuthi kungani i-ceramic iyindlela engcono kakhulu yokusethwa kwelabhorethri, umuntu kufanele ahlole ukuhlangana kwesayensi yezinto ezibonakalayo kanye ne-metrology yobukhulu.
Inzuzo Yezinto Ezibonakalayo: Ngale Kwe-Granite Nensimbi
Isizathu esiyinhloko esenza amalebhu e-metrology ashintshele ezikweleni ze-ceramic futhi imiphetho eqondile itholakala ezimfanelweni zomzimba ezingavamile zale nto. Amathuluzi amaningi e-ceramic anokunemba okuphezulu akhiwa yi-Alumina (Aluminum Oxide) noma i-Silicon Carbide, izinto ezenzelwe ukuba ziqine futhi zibe lula kakhulu.
Enye yezinselelo ezibaluleke kakhulu elabhorethri ye-metrology ithonya lamandla adonsela phansi kumathuluzi okulinganisa. Uma kusetshenziswa unqenqema olude oluqondile ukuhlola ukuthi indlela yomshini noma ipuleti elingaphezulu lisicaba, ithuluzi ngokwalo lingadlula “ekugobeni” noma ekuphambukeni ngenxa yesisindo salo. Insimbi inzima futhi iguquguquka kancane, futhi yize i-granite izinzile kakhulu, isenobunzima obukhulu. Kodwa-ke, i-ceramics inikeza isilinganiso sokuqina kwesisindo esiphakeme kakhulu. Unqenqema oluqondile lwe-ceramic lulula kakhulu kunolunye lwe-granite ngenkathi lugcina i-modulus ephezulu yokuguquguquka. Lokhu kusho ukuthi lapho uchwepheshe ephatha isikwele se-ceramic, kunokucindezeleka okuncane ngokomzimba kumqhubi futhi, okubaluleke kakhulu, ukugoba okuncane kwesakhiwo kuthuluzi ngokwalo, okuholela emgqeni wokubhekisela “weqiniso” kakhudlwana.
Ukuqina Kokushisa: Isitha Sokuphambuka
Ukulawulwa kwezinga lokushisa kuyinhliziyo yanoma yiliphi ilabhorethri ye-metrology. Ngisho nasegumbini elizinzile ku-20°C, ukushisa okuvela esandleni somuntu noma ukusondela komthombo wokukhanya we-elekthronikhi kungabangela ukwanda okuncane kakhulu ethuluzini lokubhekisela. I-ceramics ine-coefficient yokwanda kokushisa okuphansi kakhulu, ngokuvamile okuphakeme kune-granite emnyama esezingeni eliphezulu.
Ngaphezu kwalokho, izinto zobumba zine-conductivity ephansi yokushisa. Lapho uchwepheshe ethatha isikwele sensimbi, ukushisa okuvela esandleni sakhe kuhamba ngokushesha ngensimbi, okubangela ukwanda kwendawo okungasusa isilinganiso se-sub-micron. Izinto zobumba ziyamelana nalokhu kudluliselwa kokushisa. Lokhu "kungakwazi ukushisa" kuqinisekisa ukuthi ithuluzi lihlala lizinzile ngokwesilinganiso kulo lonke inqubo yokulinganisa, noma ngabe izimo zemvelo ziyashintshashintsha kancane. Kumalabhorethri enza ukulinganisa okudinga ukunemba ngaphakathi kuka-0.001mm, lokhu kuzinza kokushisa akuyona nje inzuzo - kuyisidingo.
Ukumelana Nokugqokwa Nobuqotho Bomphezulu
Elabhorethri ematasa yokulinganisa, amathuluzi okubhekisela ayashukunyiswa, ashelele, futhi athinteke kwezinye izindawo eziqinile izikhathi eziyizinkulungwane. Ngokuhamba kwesikhathi, izinto zendabuko zingabonisa izimpawu zokuguguleka. Insimbi ingakha imihuzuko emincane eholela ezimbotsheni, futhi ngisho ne-granite ingabhekana "nokuqhekeka" noma "ukuphotha" kwendawo ezindaweni ezisetshenziswa kakhulu.
Izinto zobumba ziphakathi kwezinto ezilukhuni kakhulu ezenziwe ngabantu, zilandela idayimane kwezinye izinhlelo zokusebenza zezimboni. Lobu bunzima obukhulu buholela ekumelaneni nokuguguleka okumangalisayo. Isikwele sobumba singashintshwa phezu kwepuleti lobuso begranite iminyaka eminingi ngaphandle kokulahlekelwa okulinganiselwe kokusicaba noma ukuthambekela. Ngaphezu kwalokho, i-ceramic iyinto engenazo izimbobo. Ngokungafani negranite, engamunca umswakama omncane noma uketshezi lokuhlanza okungase kuholele ezinguqukweni ezincane zobukhulu phakathi namashumi eminyaka, i-ceramic ayisebenzi nhlobo. Ayigqwali, ayigqwali, futhi imelana nama-acid namafutha avame ukutholakala ezindaweni zezimboni.
Ukusebenza Kokunemba: Ukuphatha Nokunakekela
Ngaphandle kwezincazelo zobuchwepheshe, izinzuzo ezingokoqobo zamathuluzi e-ceramic endaweni yelebhu zinkulu. Ngenxa yokuthi i-ceramic ilula kakhulu kune-granite, kulula ukuyilawula lapho uhlola ukuma kwe-Z-axis yomshini noma ukuhambisana komshini wokulinganisa ohambisanayo. Lokhu kuphatheka kunciphisa ingozi yokuwa noma ukushayisana ngengozi okungalimaza imishini ebizayo.
Ukugcinwa kwamathuluzi e-ceramic nakho kulula kakhulu. Ngenxa yokuthi izinto zokwakha ziqinile, akudingi ukuphindaphindwa njalo okungadingeka ngamathuluzi ensimbi ukuze kususwe ama-burrs. Ukuhlanza kulula, kudinga kuphela utshwala obuhlanzekile kakhulu ukuqinisekisa ukuthi indawo ayinalo uthuli. Kumphathi webhubhu ofuna ukunciphisa izindleko zesikhathi eside zokuba namathuluzi ngenkathi ekhulisa ukuthembeka kwezilinganiso zawo, izinto ze-ceramic zimelela utshalomali oluhlakaniphile nolucabangayo kusengaphambili.
Isiphetho: Ukubeka Indinganiso Yesikhathi Esizayo
Njengoba singena shí enkathini ethi “Yokukhiqiza Okukhulu,” amathuluzi esiwasebenzisayo ukuchaza “okuqondile” kanye “nesikwele” kumelwe angabi nacala. Izikwele ze-ceramic ezinembile kakhulu kanye nemiphetho eqondile zimelela ubuchwepheshe bamathuluzi okubhekisela obuphezulu. Zinikeza inhlanganisela eyingqayizivele yokukwazi ukuhamba kalula, ubulukhuni obukhulu, kanye nokuzinza kokushisa okungenakuqhathaniswa.
Kumalebhu okukala imitha kanye nezindawo zokulinganisa ezisezingeni eliphezulu, ukukhetha kucacile. Nakuba i-granite ihlala iyisisekelo esihle kakhulu sezindawo ezinkulu, ukunemba, ukuphatheka kalula, kanye nokuhlala isikhathi eside kwe-ceramic kwenza kube yinto efanelekile yamathuluzi aqinisekisa ubukhulu bethu obubaluleke kakhulu. Ngokuhlanganisa izingxenye ze-ceramic zokukala imitha elabhorethri yakho, awugcini nje ngokuthenga ithuluzi; uqinisekisa izinga lokunemba elizohlala lingashintshi iminyaka ezayo, ukuqinisekisa ukuthi yonke imitha ethathiwe iyisilinganiso esingathenjwa.
