Ithagethi Ye-Yttrium Ehlanzekile Ephakeme - Ilungu Elibalulekile Le-PVD Coating

Iyini i-yttrium sputtering target?
Ithagethi ye-Yttrium ikhiqizwa ngokuyinhloko isici sensimbi i-yttrium sputtering target, ngoba i-yttrium element (Y) ingenye yezinto ezingavamile zensimbi yomhlaba, ngakho-ke ithagethi ye-yttrium yaziwa nangokuthi ithagethi yomhlaba engavamile.
Okuqondiwe kwe-Yttrium kusetshenziswa kakhulu kubuchwepheshe bokufaka ama-sputtering. Ubuchwepheshe be-sputtering deposition bungobunye bobuchwepheshe be-physical vapor deposition (PVD), futhi bungobunye bobuchwepheshe obuyinhloko bokulungiselela izinto zefilimu ezacile zikagesi. Ngokuqhumisa ingaphezulu lethagethi ngezinhlayiya ezinamandla amakhulu (njengama-ion noma ama-electron ama-electron), ama-athomu okuqondiwe noma ama-molecule akhishwa bese afakwa kwenye i-substrate ukuze enze ifilimu noma ukunamathela okufunayo.
Ithagethi ye-yttrium imane nje iwumthombo wefilimu efiswayo noma ukunamathela okulungiselelwe ubuchwepheshe be-PVD.

YiniiIthagethi ye-yttrium sputtering esetshenziselwa?

Okuhlosiwe kwe-Yttrium kunohlu olubanzi lwezinhlelo zokusebenza emikhakheni eminingana, okulandelayo izindawo eziyinhloko zokufaka isicelo:

1. Izinto zokwakha ze-semiconductor: Embonini ye-semiconductor, okuhlosiwe kwe-yttrium kusetshenziselwa ukukhiqiza izendlalelo ezithile ezintweni ze-semiconductor noma izingxenye ze-electronic, ezifana nama-transistors, ama-circuits ahlanganisiwe, njll.
2. I-Optical coating: Emkhakheni we-optical optics, izinhloso ze-yttrium zingasetshenziswa ukulungisa izigqoko ze-optical ezinenkomba ephezulu ye-refractive kanye nezinga eliphansi lokuhlakazeka, elidlala indima ebalulekile ekukhiqizeni amadivaysi optical njengama-lasers kanye nezihlungi ze-optical.
3. Ukufakwa kwefilimu ezacile: Ithagethi ye-yttrium ithatha isikhundla esibalulekile kubuchwepheshe bokufakwa kwefilimu ezacile, futhi ubumsulwa bayo obuphezulu, ukuzinza okuhle, kanye nezakhiwo ezithile zomzimba namakhemikhali kuyenza ibe inketho ekahle yokulungiselela izinhlobonhlobo zezinto ezincane zefilimu. Lezi zinto zefilimu ezacile zinezinhlobonhlobo zezinhlelo zokusebenza ku-optical, electronic, magnetic, kanye neminye imikhakha.
4. Inkambu yezokwelapha: okuqondiwe kwe-yttrium kunokusebenza okubalulekile emithini yokukhishwa kwemisebe, njengomthombo wama-X-reyi nemisebe ye-gamma, isithombe sokuxilonga (njenge-CT scan), kanye nokwelapha ngemisebe. Ngaphezu kwalokho, ama-isotopes athile e-yttrium (afana ne-Y-90) angasetshenziswa kuma-radiopharmaceuticals ekwelapheni okuhlosiwe komdlavuza othize.
5. Imboni yamandla enuzi: Kuma-reactors enuzi, okuqondiwe kwe-yttrium kusetshenziswa njengezinto ezisetshenziswayo zokulawula isivinini nokuzinza kokusabela kwe-nuclear ngenxa yomthamo wazo omuhle kakhulu wokumunca i-neutron.

Qaphela: Njengoba izimfuneko zokusebenza kokuhlosiwe kwe-yttrium emikhakheni ehlukene yohlelo lokusebenza zingase zehluke, okuqondiwe okufanelekile kudinga ukukhethwa ngokuya ngesimo sangempela kuhlelo lokusebenza oluthile. (Njengokuhlanzeka okuthile, isilinganiso sokwakheka, usayizi, umumo, njll., okwenziwe ngokwezifiso ngokuya ngezidingo ezithile.)

Ubuchwepheshe bokukhiqiza bezinhloso ze-yttrium sputtering?

1. Lungiselela i-yttrium powder 2. I-HIP, ukucindezela ukubumba 3. Ukushisa okuphezulu kwe-sintering 4. Ukucubungula okulandelayo (Ukusika, ukupholisha, njll.) 5. Ukuhlanza nokupakisha

Qaphela:Ngaphandle kwalezi zinyathelo eziyisisekelo ezingenhla, ngokwendlela ethile yokulungiselela kanye nezidingo zohlelo lokusebenza, izinhloso ze-yttrium sputtering zingase futhi zibandakanye ezinye izinyathelo nobuchwepheshe, njengendlela yokufaka isiphalaphala, indlela yokuncibilika kwevacuum, njll. Lezi zindlela zisiza ukuqhubekela phambili ukulungisa nokwenza kahle ukusebenza kanye nokwakheka kwezinto eziqondiwe.

Ungakhetha kanjani i-sputtering target yekhwalithi ephezulu?

Okulandelayo kuklelisa izici ezingu-7 ezibalulekile zokukhetha okuhlosiwe kwekhwalithi ephezulu:

1.Sawubonagh ubumsulwa

Okuhloswe ukuhlanzeka okuphezulu kunezinto ezibonakalayo ezingcono kanye nezakhiwo ezizinzile zomzimba namakhemikhali, okubalulekile ukuze kuqinisekiswe ikhwalithi nokusebenza kwezingubo zokugcoba. Izidingo ezithile zokuhlanzeka kufanele zinqunywe ngokuya ngesimo sohlelo lokusebenza, ezinye izimo ezilula zohlelo azidingi ukuphishekela ukuhlanzeka okuphezulu, ukuze zingakhulisi izindleko ezingadingekile. Okufanelana nawe kungcono kakhulu.

2.Ukuzinza

Ukuzinza kwethagethi kubaluleke ngokufanayo, okungagwema ukulahleka kwezinto noma ukushintshashintsha kokusebenza ngesikhathi sokufafaza. Ngakho-ke, ekukhethweni, umuntu ukhetha lokho kwelashwa okukhethekile noma abe nokuzinza okuhle komkhiqizo.

3.Ubukhulu kanye nesimo

Ubukhulu kanye nokuma kwethagethi ye-sputtering kufanele kukhethwe ngokuvumelana nezidingo ezithile zemishini yokuhlanganisa ukuze ivumelane nezinqubo ezahlukene zokufafaza kanye nezidingo zokukhiqiza. Ukuqinisekisa ukuthi okuhlosiwe kufaniswe nempahla kwandisa ukusebenza kahle kwe-sputtering futhi kunciphisa imfucuza.

4.Ukuminyana

Ukuminyana kungenye yezinkomba ezibalulekile zokukala ikhwalithi yezinto eziqondiwe. Izinto ezihloselwe ukuminyana okuphezulu zingaqinisekisa umphumela ongcono we-sputtering. Lapho ukhetha, kufanele unake idatha yokuminyana kokuhlosiwe, bese uzama ukukhetha imikhiqizo enomthamo omkhulu.

5.Ukunemba kokucubungula

Ukunemba kokucubungula kokuhlosiwe nakho kungenye yezinto okudingeka zibhekwe. Ngokuvamile, ukunemba kokucubungula kokuhlosiwe kuyadingeka ukuthi kube phakathi kuka-±0.1mm ukuze kuqinisekiswe ukuzinza kwenqubo yokufafaza nokufana kwekhwalithi yokumboza.

6.Izidingo ezikhethekile

Kwezinye izimo zohlelo lokusebenza olukhethekile, njengesidingo sokudluliswa kokukhanya okuphezulu, ukumuncwa okuphansi kwethagethi (i-optical coating) noma ukuhanjiswa okuphezulu, ukuzinza okuphezulu kwethagethi (inkambu ye-elekthronikhi), kufanele kukhethwe ngokuya ngezidingo ezithile zethagethi ehambisanayo. uhlobo.

7.Khetha umkhiqizi ochwepheshe noma umphakeli.
