I-Molybdenum isoloko isetyenziswa njengento ekujoliswe kuyo kwi-mammography ngenxa yeempawu zayo ezifanelekileyo zokujonga izicubu zebele. I-Molybdenum inenani leathom elisezantsi, nto leyo ethetha ukuba ii-X-reyi eziyivelisayo zilungele ukwenza umfanekiso wezicubu ezithambileyo ezifana nebele. I-Molybdenum ivelisa iimpawu zeX-reyi kumanqanaba asezantsi amandla, izenza zilungele ukujonga iiyantlukwano ezifihlakeleyo kuxinaniso lwezicubu zamabele.

Ukongezelela, i-molybdenum ineempawu ezintle ze-thermal conductivity, ezibalulekileyo kwizixhobo ze-mammography apho ukubonakaliswa okuphindaphindiweyo kwe-X-ray kuqhelekileyo. Ukukwazi ukukhupha ukushisa ngokufanelekileyo kunceda ukugcina uzinzo kunye nokusebenza kweetyhubhu ze-X-ray kwixesha elide lokusetyenziswa.

Ngokubanzi, ukusetyenziswa kwe-molybdenum njengento ekujoliswe kuyo kwi-mammography inceda ukunyusa umgangatho womfanekiso webele ngokubonelela ngeempawu ezifanelekileyo ze-X-ray kwesi sicelo esithile.

Ithagethi ye-sputter yinto esetyenziswa kwinkqubo yokubeka umphunga womzimba (PVD) ukwenza iifilimu ezibhityileyo okanye iingubo kwii-substrates. Ngethuba lenkqubo yokutshiza, i-ion beam ephezulu yamandla ibhobhoza i-sputtering target, ibangela ukuba ii-athomu okanye iimolekyuli zikhutshwe kwizinto ezijoliswe kuzo. La masuntswana atshiziweyo afakwe kwi-substrate ukwenza ifilimu encinci kunye nokwakheka okufanayo kunye nethagethi ye-sputtering.

Iithagethi ze-sputtering zenziwe kwizinto ezahlukeneyo, kubandakanywa isinyithi, i-alloys, i-oxides kunye nezinye izinto ezixutywe, kuxhomekeke kwiipropati ezifunwayo zefilimu egciniweyo. Ukukhethwa kwezinto ezijoliswe kwi-sputtering kunokuchaphazela kakhulu iipropati zefilimu ebangelwayo, ezifana ne-conductivity yayo yombane, i-optical properties okanye i-magnetic properties.

Iithagethi ze-sputtering zisetyenziswa ngokubanzi kumashishini ahlukeneyo afana nokuvelisa i-semiconductor, i-optical coating, kunye neeseli zelanga zefilimu ezincinci. Ulawulo oluchanekileyo lojoliso lwe-sputtering ekubekweni kwefilim ebhityileyo lubenza babaluleke kakhulu ekuvelisweni kwezixhobo ezikumgangatho ophezulu zombane kunye nezixhobo zokukhanya.

Kukho iingqwalasela ezininzi ezibandakanyekayo ekukhetheni nasekusebenziseni iithagethi ze-molybdenum ukuze usebenze ngokugqibeleleyo:

1. Ukucoceka kunye nokubunjwa: Izinto ezijoliswe kuzo ze-molybdenum eziphezulu ezihlambulukileyo zikhethiweyo ukuze kuqinisekiswe ukusebenza okuhambelanayo kunye nokuthembekileyo kwe-sputtering. Ukuqulunqwa kwethagethi ye-molybdenum kufuneka ilungelelaniswe kwiimfuno ezithile zokubeka ifilimu, njengeempawu zefilimu ezifunwayo kunye neempawu zokubambelela.

2. Ulwakhiwo lweenkozo: Nika ingqalelo kwisakhiwo senkozo yethagethi ye-molybdenum njengoko iya kuchaphazela inkqubo yokutshiza kunye nomgangatho wefilimu ediphozithiweyo. Iithagethi ze-molybdenum ezine-fine-grained ziphucula ukufana kwe-sputtering kunye nokusebenza kwefilimu.

3. Ijometri ekujoliswe kuyo kunye nobukhulu: Khetha ijometri efanelekileyo kunye nobukhulu ukuze utshatise inkqubo ye-sputtering kunye neemfuno zenkqubo. Uyilo olujoliswe kuyo kufuneka luqinisekise ukutshiza okusebenzayo kunye nokufakwa kwefilimu efanayo kwi-substrate.

4. Ukupholisa kunye nokutshatyalaliswa kobushushu: Iindlela ezifanelekileyo zokupholisa kunye nokutshatyalaliswa kobushushu kufuneka zisetyenziswe ukulawula iziphumo ze-thermal ngexesha lenkqubo yokutshiza. Oku kubaluleke ngakumbi kwiithagethi ze-molybdenum, njengoko zichaphazeleka kwiingxaki ezinxulumene nobushushu.

5. Iiparamitha ze-sputtering: Lungiselela iiparamitha zokutshiza ezifana namandla, uxinzelelo, kunye nokuhamba kwegesi ukufezekisa iipropati zefilimu ezifunwayo kunye namazinga okubeka ngelixa unciphisa ukukhukuliseka okujoliswe kuyo kunye nokuqinisekisa ukusebenza okujoliswe kuyo ixesha elide.

6. Ukugcinwa kunye nokuPhathwa: Landela i-molybdenum ekhuthazwayo yokuphathwa kwethagethi, ukufakela kunye neenkqubo zokulondoloza ukwandisa ubomi benkonzo kunye nokugcina ukusebenza kwe-sputtering engaguqukiyo.

Ngokuqwalasela le miba kunye nokuphunyezwa kweendlela ezilungileyo xa ukhetha kwaye usebenzisa iithagethi ze-molybdenum, ukusebenza ngokufanelekileyo kwe-sputtering kunokufezekiswa, okukhokelela ekufakweni kwefilimu ebhityileyo ephezulu kwizicelo ezahlukeneyo.
