UFerro Tungstenama-alloys ngokuvamile abhekisela kuma-alloys akhiwe i-tungsten (W) ne-iron (Fe). Ngokuvamile,
i-tungsten-iron alloysawanawo uzibuthe. Lokhu kungenxa yokuthi i-tungsten ngokwayo iyinsimbi engeyona i-magnetic, futhi okuqukethwe kwensimbi kuma-tungsten-iron alloys ngokuvamile kuphansi, okungakwazi ukunikeza i-alloy i-magnetism ebalulekile.
I-Tungsten kanye Nozibuthe Wayo
I-Tungsten, evame ukubizwa ngokuthi i-tungsten, iyikhemikhali enenombolo ye-athomu engu-74 kanye nophawu lwe-W. Izakhi kazibuthe zivame ukubizwa ngokuthi izakhi ze-ferromagnetic, ezibonakala ngama-electron angabhanqiwe. I-Tungsten iphinde ibe nama-electron angabhanqiwe egobolondweni layo elingaphandle, elivumela ukuthi libonise uhlobo oluthile lwe-magnetism. Ama-electron aya endaweni yangaphandle kazibuthe, akhiqize umzuzu kagesi okwenza uthandeke kancane endaweni kazibuthe.
Kodwa-ke, i-tungsten nayo ine-dipole ehamba ngokuphambene nethonya langaphandle, elivimbela amandla kazibuthe. Lokhu kuyenza ibonise i-paramagnetism.
Ingabe i-Tungsten Alloy Magnetic?
Ukuthi ama-tungsten alloys angabonisa i-magnetism kuncike ensimbi ahlanganiswe kuyo. Lawa ma-alloys ahlanganiswe nensimbi eyinhloko kanye nezakhi ezihlukahlukene zokulandelela.
Eqinisweni, i-tungsten ingasetshenziselwa ukwakha ama-alloys amaningi angase abe nezakhiwo ezihlukene kazibuthe.
Isibonelo, insimbi ye-tungsten inozibuthe ngoba iqukethe insimbi equkethe i-ferromagnetic iron. Lokhu kuphinde kube namanani omkhondo we-vanadium ne-molybdenum kanye ne-tungsten okungenani engu-8%.
I-Tungsten carbide nayo ingabonisa uzibuthe, kuye ngezinye izinsimbi ezisetshenziswa enqubweni yokuhlanganisa. I-Tungsten carbide idinga insimbi ebophayo ukuze ixube kahle futhi ukukhetha kwensimbi kuthinta izakhiwo zayo kazibuthe. Uma i-cobalt noma insimbi ifakwe ku-alloy izoba kazibuthe, ngakolunye uhlangothi uma i-nickel isetshenziswa khona-ke izoba kazibuthe.
Izinto Ezithinta I-Tungsten Magnetism
Kunezici eziningana ezithinta izakhiwo kazibuthe ze-tungsten. Lezi zici zihlanganisa:
Izinga lokushisa:Lesi sici sincike emthethweni we-Curie othi ukuba sengozini kazibuthe kwe-paramagnetic material kuhambisana ngokuphambene nezinga lokushisa. Ukwanda kwezinga lokushisa kunciphisa ukuthinteka kazibuthe, okuholela ekwehleni kokuphendula kazibuthe. Amazinga okushisa aphansi anomphumela ophambene futhi andisa izakhiwo kazibuthe ze-tungsten.
Inkambu kazibuthe esetshenzisiwe:Inkambu kazibuthe esetshenziswayo ithinta umumo wama-electron ku-tungsten. Inkambu kazibuthe enamandla ivumela isici ukuthi sithole amakhono kazibuthe abuthaka esikhashana anyamalalayo lapho indawo kazibuthe isisusiwe.
Okuqukethwe kwe-binder:Kuma-alloys e-tungsten, izakhi ze-binder zisetshenziselwa ukuncibilikisa izakhi ezahlukahlukene. Isibonelo, i-cobalt yaziwa ngokuthuthukisa lezi zakhiwo, kuyilapho i-nickel ivimbela umphumela osuvele unomkhawulo, okwenza isici singabi nguzibuthe.
Ukwakhiwa:Ukwakheka okuqondile kwalesi sakhi kuthinta ngokuqondile izakhiwo kazibuthe ze-tungsten kanye nenani lama-electron angabhanqiwe kanye nokuba khona kwama-dipoles nokuhlelwa kwawo.
Izicelo kanye Nokubaluleka Tungsten
Njengento ebalulekile yensimbi,
i-tungsteninezinhlobonhlobo zezicelo kanye nokubaluleka emikhakheni yezimboni nesayensi nobuchwepheshe. Okulandelayo yizicelo eziyinhloko nokubaluleka kwe-tungsten:
1. Ukukhiqiza ingxubevange yokushisa ephezuluI-Tungsten inezinga eliphezulu lokuncibilika kanye nezakhiwo zamandla aphezulu, okuyenza ibe yingxenye ebalulekile ekwakhiweni kwama-alloys asezingeni eliphezulu. Lawa ma-alloys asezingeni eliphezulu avame ukusetshenziswa endaweni ye-aerospace, ezinjinini zezindiza, amandla enuzi nezimboni zamakhemikhali, futhi angakwazi ukumelana nezinga lokushisa eliphakeme ngokwedlulele kanye nezimo zengcindezi.
2. Amathuluzi okusika nama-abrasivesNgenxa yokuqina okuphezulu nokumelana nokugqoka kwe-tungsten, ama-tungsten alloys avame ukusetshenziswa ekwenzeni amathuluzi okusika, ama-drill, abrasives namathuluzi okugaya. Lawa mathuluzi adlala indima ebalulekile ekusetshenzisweni kwensimbi, izimayini nezinye izimboni.
3. Imboni yezogesi
I-Tungsten isetshenziswa kabanzi embonini ye-elekthronikhi ukwenza ama-electrode, amashubhu e-vacuum, amadivaysi kagesi kanye namadivayisi we-semiconductor. Iphuzu layo eliphezulu lokuncibilika kanye nokuzinza kuyenza ibe enye yezinto ezifanelekile zemishini kagesi.
4. Inkambu yezokwelapha
Ama-Tungsten alloys asetshenziselwa ukwenza izinto zezokwelapha, izinto zokuvikela imisebe kanye nemishini yokwelapha nge-radiotherapy. Ukuminyana kwayo okuphezulu kanye nezakhiwo zokuvikela imisebe kuyenza ibe isicelo esibalulekile emkhakheni wezokwelapha.

5. Inkambu yamandla enuzi
I-Tungsten isetshenziswa kabanzi emkhakheni wamandla enuzi ukwenza izinto zokulawula ukusabela kweziphehlisi zenuzi nezinye izinto zamandla enuzi. Ukuminyana kwayo okuphezulu nendawo encibilika kuyo kuyenza ibe inketho efanelekile yezinto ezisetshenziswayo zamandla enuzi.
6. Ezinye izinhlelo zokusebenza
I-Tungsten iphinde isetshenziselwe ukwenza ama-alloys aphezulu kakhulu, amadivaysi e-aerospace, amalensi optical, izingxenye zezimoto, njll. Ukusetshenziswa kwayo emikhakheni ehlukahlukene yezimboni kube negalelo elikhulu.
Ngamafuphi, i-tungsten, njengento ebalulekile yobunjiniyela, inezici eziyingqayizivele zomzimba namakhemikhali, okwenza idlale indima ebalulekile emikhakheni eminingi. Ukuqina kwayo okuphezulu, indawo encibilikayo ephezulu, ukumelana nokugqwala kanye nokuzinza kohlangothi kuyenza ibe ngenye yezinto ezibalulekile emikhakheni eyahlukene yezimboni nesayensi. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, inkambu yesicelo se-tungsten izoqhubeka nokukhula futhi ibe negalelo elikhulu ekuthuthukisweni nasekuthuthukisweni komphakathi wesintu.
