Kwihlabathi le-metrology ephezulu kunye nokulinganiswa ngokuchanekileyo, ukuphishekela ukulinganisa okungenampazamo luhambo oluqhubekayo. Njengoko amashishini afana ne-aerospace, i-semiconductor lithography, kunye nokuveliswa kwezixhobo zonyango zityhala imida yoko kunokwenzeka kwisikali se-nanometer, izixhobo ezisetyenziselwa ukuqinisekisa ezi milinganiselo kufuneka ziguquke. Ngelixa i-granite kunye nentsimbi zisebenze njengemigangatho yendabuko yezixhobo zokubhekisa, inkokeli entsha ivele kwiindawo ezifuna kakhulu: ii-ceramics zobugcisa ezisebenza kakuhle. Izikwere ze-ceramic ezichanekileyo kakhulu kunye nemiphetho ethe tye ngokukhawuleza ziba lukhetho olukhethwayo kwiilabhoratri ze-metrology ezingenako ukuyekelela ekuchanekeni.
Ukutshintshela kwizinto zeseramikhi kuqhutywa yimfuno esisiseko yozinzo edlula imida yendalo yelitye lendalo kunye nee-alloys zesinyithi. Ukuze uqonde ukuba kutheni iseramikhi ilukhetho oluphezulu kwindawo yelabhoratri, umntu kufuneka ahlole ukudibana kwesayensi yezinto kunye ne-dimensional metrology.
Inzuzo yezinto ezibonakalayo: Ngaphaya kweGranite kunye neNtsimbi
Eyona nto iphambili eyenza ukuba iilebhu zemetrology zitshintshele kwizikwere zeseramikhi kwaye imiphetho ethe tye ikwiimpawu zomzimba ezingaqhelekanga zesixhobo. Uninzi lwezixhobo zeseramikhi ezichanekileyo zenziwe ngeAlumina (Aluminum Oxide) okanye iSilicon Carbide, izinto ezenzelwe ukuba ziqine kwaye zibe lula kakhulu.
Enye yezona ngxaki zibalulekileyo kwilebhu ye-metrology yimpembelelo yomxhuzulane kwizixhobo zokulinganisa. Xa kusetyenziswa umda omde othe tye ukujonga ukuba indlela yomatshini okanye ipleyiti yomphezulu ityibilika kangakanani, isixhobo ngokwaso sinokuwela okanye sijike ngenxa yobunzima baso. Intsimbi inzima kwaye iguquguquka kancinci, kwaye nangona igranite izinzile ngakumbi, isenobunzima obukhulu. Nangona kunjalo, iiceramics zibonelela ngomlinganiselo ophezulu wokuqina-ubunzima. Umda othe tye weceramic ulula kakhulu kunegranite counterpart yayo ngelixa ugcina imodulus ephezulu yokuqina. Oku kuthetha ukuba xa ingcali iphatha isikwere seceramic, akukho xinzelelo lomzimba kumqhubi kwaye, okubaluleke ngakumbi, akukho tshintsho lolwakhiwo kwisixhobo ngokwaso, nto leyo ekhokelela kumgca wereferensi "oyinyani" ngakumbi.
Ukuqina kobushushu: Utshaba lokuphambuka
Ulawulo lobushushu luyindlela yokubetha kwentliziyo yayo nayiphi na ilebhu ye-metrology. Nokuba kwigumbi elizinzileyo kwi-20°C, ubushushu obuvela esandleni somntu okanye ukusondela komthombo wokukhanya we-elektroniki kunokubangela ukwanda ngemicroscope kwisixhobo sokubhekisa. Iiseramikhi zine-coefficient yokwanda kobushushu ephantsi kakhulu, edla ngokuba ngaphezulu kunegranite emnyama ekumgangatho ophezulu.
Ngaphezu koko, iiseramikhi zine-thermal conductivity ephantsi. Xa ingcali ithatha isikwere sentsimbi, ubushushu obuvela esandleni sayo buhamba ngokukhawuleza kwisinyithi, nto leyo ebangela ukwanda kwendawo okunokukhupha umlinganiselo we-sub-micron. Iiseramikhi ziyamelana nolu dluliselo lobushushu. Olu "xinzelelo lobushushu" luqinisekisa ukuba isixhobo sihlala sizinzile ngokwemilinganiselo kulo lonke inkqubo yokulinganisa, nokuba iimeko zendalo ziyatshintshatshintsha kancinci. Kwiilabhoratri ezenza ukulinganiswa okufuna ukuchaneka ngaphakathi kwe-0.001mm, olu zinzo lobushushu aluyonto nje iluncedo—luyimfuneko.
Ukumelana nokuNxiba kunye noBuchule bomphezulu
Kwilabhoratri exakekileyo yokulinganisa, izixhobo zokubhekisa ziyashukunyiswa, zityibilike, kwaye zichukunyiswe kwezinye iindawo eziqinileyo amaxesha amaninzi. Ngokuhamba kwexesha, izinto zemveli zinokubonisa iimpawu zokuguguleka. Intsimbi inokwenza imikrwelo emincinci ekhokelela kwi-burrs, kwaye ne-granite inokuba namava "okubetha" okanye "umgubo" womphezulu kwiindawo ezisetyenziswa kakhulu.
Iiceramics ziphakathi kwezinto ezilukhuni ezenziwe ngumntu, zilandela idayimani kwezinye iinkqubo zoshishino. Olu bunzima bugqithisileyo buthetha ukumelana nokuguguleka okumangalisayo. Isikwere seceramic sinokutyibilika kwipleyiti yomphezulu wegranite kangangeminyaka ngaphandle kokulahlekelwa bubucaba okanye ukuthambeka. Ukongeza, iceramic yinto engenazimbobo. Ngokungafaniyo negranite, enokufunxa ubuninzi obuncinci bomswakama okanye ulwelo lokucoca olunokukhokelela kutshintsho oluncinci lobukhulu kwiminyaka emininzi edlulileyo, iceramic ayisebenzi ngokupheleleyo. Ayigqwali, ayigqwali, kwaye iyamelana nee-asidi kunye neeoyile ezifumaneka rhoqo kwiindawo zoshishino.
Ubuchule Bokuchaneka: Ukuphatha Nokugcina
Ngaphaya kweenkcukacha zobugcisa, iingenelo ezisebenzayo zezixhobo zeseramikhi kwindawo yelebhu zinkulu kakhulu. Ngenxa yokuba iseramikhi ilula kakhulu kunegranite, kulula ukuyilawula xa ujonga ukuma kwe-Z-axis yomatshini okanye ukulungelelaniswa komatshini wokulinganisa ohambelanayo. Oku kuthwaleka kunciphisa umngcipheko wokuwa ngengozi okanye ukungqubana okunokonakalisa izixhobo ezibizayo.
Ukugcinwa kwezixhobo zeseramikhi nako kulula kakhulu. Ngenxa yokuba izinto ezisetyenzisiweyo ziqinile, azidingi ukuphindaphindwa rhoqo ukuze kususwe izikhonkwane zentsimbi. Ukucoca kulula, kufuna kuphela utywala obucocekileyo ukuqinisekisa ukuba umphezulu awunaluthuli. Kumphathi webhubhoratri ojonge ukunciphisa iindleko zexesha elide zokuba nezixhobo ngelixa enyusa ukuthembeka kwemilinganiselo yazo, iiseramikhi zimele utyalo-mali olukrelekrele nolucinga phambili.
Isiphelo: Ukumisela uMgangatho wexesha elizayo
Njengoko singena nzulu kwixesha "leMveliso egqithisileyo," izixhobo esizisebenzisayo ukuchaza "ithe tye" kunye "nesikwere" kufuneka zingabi nasiphako. Izikwere zeseramikhi ezichanekileyo kakhulu kunye nemiphetho ethe tye zimele eyona nto iphambili kwitekhnoloji yezixhobo zokubhekisa. Zibonelela ngomxube owahlukileyo wokuhamba okulula, ubunzima obukhulu, kunye nokuzinza kobushushu okungenakuthelekiswa nanto.
Kwiilabhoratri zemetrology kunye nezibonelelo zokulinganisa eziphezulu, ukhetho lucacile. Nangona igranite ihlala isisiseko esihle kakhulu seendawo ezinkulu, ukuchaneka, ukuthwaleka, kunye nokuhlala ixesha elide kweceramic kuyenza ibe yeyona nto iphambili kwizixhobo eziqinisekisa ubukhulu bethu obubalulekileyo. Ngokudibanisa izinto zemetrology zeceramic kwilabhoratri yakho, awuthengi nje isixhobo; uqinisekisa umgangatho wokuchaneka oya kuhlala ungatshintshi kangangeminyaka ezayo, uqinisekisa ukuba yonke imilinganiselo ethathiweyo yimilinganiselo enokuthenjwa.
