Ukusika kwamangqamuzana: kuyini nokuthi kusetshenziselwa ini

ukusika kwamangqamuzana

Sengivele nginikezele isihloko esandulele esihlokweni sokusikeka nge Imishini ye-CNC, kodwa manje siqhubekela phambili, futhi ngizozama udaba lokusika kwamangqamuzana, okuwuhlobo olusha lokusika oluvunyelwe ubuchwepheshe obusha futhi oluvumela ukusikeka okuyinkimbinkimbi kakhulu ukuthi kwenziwe cishe ngokunemba okuphelele.

Eqinisweni, kunjalo ngokunemba, osekucishe kwaba igciwane kwezinye izinkundla zokuxhumana, njengoba amavidiyo acishe abe yi-hypnotic njengoba uzobona kamuva...

Kuyini ukusika kwamangqamuzana?

I-FIB

Emkhakheni wezimboni, ubuchwepheshe obusha buyafunwa kakhulu obuvumela izinto eziyisisekelo ukuthi zenziwe ngendlela ephumelelayo nebonakalayo, futhi kulokhu kusesha okunembayo nokulawula ekusetshenzisweni kwezinto, kufinyelelwe amazinga amasha nathakazelisa ngokwandayo. Yena ukusika kwamangqamuzana, owaziwa nangokuthi i-focused ion beam ablation noma i-FIB (i-Focused Ion Beam), ivela njengethuluzi elibalulekile lokuhlola nokuguqula izinto ezisetshenziswa esikalini se-nanometric.

Kuyisu ukuthi isebenzisa i-ion beam egxilile ukuze iqophe izinto ngokunemba okungakaze kubonwe ngaphambili, ukususa izinto ezingeni lama-athomu noma ama-molecule. Le nqubo isekelwe ekusebenzelaneni phakathi kwama-ion anamandla amakhulu nama-athomu ento eqondiwe, okubangela ukuhlakazeka nokuqedwa kwama-athomu, okuholela ekwakhekeni kwesikhala noma isakhiwo esinezinhlangothi ezintathu esinomumo oyifunayo.

El ukusebenza kwe-molecular cutting Ingahlukaniswa izigaba ezintathu eziyinhloko:

  1. Isizukulwane se-ion: I-ion beam ikhiqizwa yi-ionization yama-athomu noma ama-molecule, ngokuvamile kusetshenziswa umthombo we-ion njengesibhamu se-sputtering ion noma umthombo we-plasma.
  2. Ukugxila kanye nokusheshisa: Ama-ion akhiqiziwe agxilile futhi asheshiselwa kumandla aphezulu, ngokuvamile ebangeni lamandla phakathi kwe-keV ne-MeV, kusetshenziswa isistimu yokubona noma ye-electrostatic. Amandla e-kinetic ama-ion anquma ukujula kokungena kumpahla eqondiwe, enamandla kakhulu ekwazi ukungena ngamasentimitha ambalwa ngisho nasezinsimbini ezinzima kakhulu.
  3. Ukusebenzisana nezinto: I-ion beam egxilile ithinta into eqondiwe, ihlangana nama-athomu ayo. Lokhu kusebenzisana kungabangela ukuhlakazeka nokuqedwa kwama-athomu, okuholela ekwakhekeni kwesikhala noma isakhiwo esinezinhlangothi ezintathu ezinomumo oyifunayo.

Ngempela ubuciko abumusha, yayisivele isetshenziswa emikhakheni efana nama-semiconductors ekuqoshweni noma ekufakweni kwezinto ezibonakalayo, noma kunjalo, ukuphelela kwale mishini kwenze kwaba nokwenzeka ukuthi iphinde igxumele kweminye imikhakha yezimboni, njengaleyo eyenza izingxenye zensimbi eziyinkimbinkimbi, phakathi kwabanye.

Ukusika amangqamuzana kuyindlela yokuziphendukela kwemvelo engaguquki, enamandla amakhulu okuguqula izinkambu ezihlukahlukene zesayensi nezobuchwepheshe. Intuthuko ekwenziweni kwe-ion, ukugxila kanye nokulawulwa kwemishayo kuzonika amandla amazinga aphezulu okunemba nokuxazulula. Ngaphezu kwalokho, ukuhlanganiswa kwamasu okusika amangqamuzana nezinye amathuluzi e-microfabrication izovula amathuba amasha okwakhiwa kwemishini ye-nanometric nezakhiwo ezinezakhiwo nemisebenzi engakaze ibonwe ngaphambili. Lezi zinhlobo zamadivayisi ziba ngokushesha futhi zishibhile, nakuba zisenazo izintengo ezingavumelekile kubantu abaningi abafayo, kodwa ubani owaziyo uma ngolunye usuku zizoshibhile ngokwanele ukuzisebenzisa ekhaya, noma mhlawumbe zihlanganiswe kumaphrinta we-3D wesikhathi esizayo ukuze kuthuthukiswe ukukhiqiza okungeziwe...

Izinzuzo zokusika amangqamuzana

Ukusika kwamangqamuzana kunikeza uchungechunge lwe izinzuzo ngaphezu kwamanye amasu okusika, njengemishini, i-lithography, njll., njenge:

  • Ukunemba ngokwedlulele: ikuvumela ukuthi usebenze esikalini se-nanometer, ngokulungiswa okungafika kuma-nanometer ambalwa.
  • Ukuvumelana nezimo- Ingasetshenziswa ukuqopha izinhlobonhlobo zezinto zokwakha, kufaka phakathi izinsimbi, ama-semiconductors, ama-polymers ngisho nezinto eziphilayo, kanye nokusika okuphelele.
  • Ukulawula okunembile: ikuvumela ukuthi udale izakhiwo eziyinkimbinkimbi ezinezinhlangothi ezintathu ngokunemba okukhulu nemininingwane, okukuvumela ukuthi ukhiqize izingxenye ezithuthukile.
  • akekho othintana naye: akudingi ukuthintana ngokomzimba nezinto ezibonakalayo, okunciphisa umonakalo nokungcoliswa, njengoba ezinye izinhlobo zokusikeka zingabangela uma sizibona ngesibonakhulu, njengokusikeka kusetshenziswa amasaha, i-plasma, njll., konke kushiya ngemuva okusobala kakhulu amamaki, ngaphezu kokuqeda inani elikhulu lezinto ezibonakalayo, okusho ukuthi awalingani ngokunembile.

Izicelo zokusika amangqamuzana

I-molecular cut ithola izicelo emikhakheni eyahlukene, kufaka phakathi:

  • I-Nanofabrication- Isetshenziselwa ukudala amadivaysi kagesi amancane, izinzwa, ama-actuator, nezinye izakhiwo ze-nanoscale, njenge-MEMS noma amadivayisi we-NEMS.
  • Isayensi yezinto ezibonakalayo: ikuvumela ukuthi ufunde isakhiwo kanye nezakhiwo zezinto ezingeni le-nanometric.
  • biology kanye nemithi: esetshenziselwa ukukhohlisa amaseli, izicubu nezinye izinto zebhayoloji, noma ukwenza ukungenelela okunembe kakhulu ngomonakalo omncane.
  • Ukulungisa idivayisi: ikuvumela ukuthi ulungise okungalungile emishinini kagesi nakwezinye izingxenye ze-miniaturized.
  • arte: Uma kubhekwa ukuphelela kwalokhu kusikeka, imisebenzi yobuciko yangempela ingenziwa, ama-puzzle ahlangana kahle, ngaphandle kokubonakala anokusikwa esiqeshini, njengezibonelo ozibone kuvidiyo yokuqala.

Ezinye izindlela

CNC laser ukusika nokuqopha

I-molecular cut has ezinye izindlela embonini, ishibhile kakhulu, kodwa futhi nokunemba okuphansi kakhulu. Isibonelo, kufanele sigqamise:

  • I-Lithography: I-Lithography iyindlela esetshenziswa kabanzi ekwenzeni amasekhethi ahlanganisiwe namanye amadivaysi e-microelectronic, kanye ne-MEMS. Ukwenza lokhu kwenzeke, umshini usetshenziswa nephethini ezodlula ukukhanya (zikhona nezinye izindlela zokuthatha izithombe ezifana ne-EBL noma i-electron beam lithography) ngawo, ukuze kushintshwe izici zento ethatha izithombe, bese ihlasela ngamakhemikhali izinqubo ekugezeni kwe-asidi, futhi ngaleyo ndlela udwebe izingxenye ozifunayo, kuze kube phansi. Lokhu kuvumela ukulungiswa okuphezulu, kodwa futhi kuyinkimbinkimbi kakhulu futhi kuyabiza ngenxa yemishini edingekayo uma izokhiqizwa ngezinqumo eziphezulu.
  • I-Electrical Discharge Machining (EDM): kuyindlela yokwenza esebenzisa ugesi ukucekela phansi impahla. Kusekelwe esimisweni sokuthi amandla kagesi agxilwe endaweni encane, okwenza umzila we-plasma oncibilika futhi uhwamulise impahla. Izinzuzo ukuthi zingasetshenziswa ezintweni ezihlukahlukene, okuvumela ukudala izimo eziyinkimbinkimbi ezintathu-ntathu, futhi akudingi ukuthintana njenge-FIB, noma kunjalo, ayinakho ukunemba okuphezulu njengokusika kwamangqamuzana, ijubane layo ihamba kancane, futhi ikhiqiza ukushisa okukhulu okungalimaza izinto ezibucayi.
  • ukusika laser: Kuyindlela evumela ukusika futhi ngokunemba okuphezulu, nakuba kungenjalo njengokusikeka kwamangqamuzana. Iphinde inikeze i-prototyping esheshayo kanye nejometri eyinkimbinkimbi, kodwa izinto ezingasikwa kanye nokujula kungase kube nemikhawulo.
