Ferro Tungstenalloys anowanzo reva alloys anoumbwa ne tungsten (W) uye iron (Fe). Kazhinji kutaura,
tungsten-iron alloysasiri magineti. Izvi zvinodaro nekuti tungsten pachayo isimbi isiri-magineti, uye iyo iron yemukati mune tungsten-iron alloys inowanzo yakaderera, iyo isingakwanise kupa iyo alloy yakakosha magineti.
Tungsten uye Magnetism Yayo
Tungsten, inowanzonzi tungsten, ikemikari ine nhamba yeatomu 74 uye chiratidzo W. Magnetic elements inowanzonzi ferromagnetic elements, iyo inoratidzirwa nemaerekitironi asina kupetwa. Tungsten inewo maerekitironi asina kupetwa mugoko rayo rekunze, zvichiita kuti iratidze imwe nzira yemagnetism. Ma electrons anofamba akananga kunze kwemagnetic field, achigadzira nguva yemagetsi inoita kuti inakidze zvishoma kune magnetic field.
Nekudaro, tungsten zvakare ine dipole inofamba ichienda kune yakapesana neiyo yekunze pesvedzero, iyo inodzivirira yayo magineti. Izvi zvinoita kuti iratidze paramagnetism.
Is Tungsten Alloy Magnetic?
Kuti tungsten alloys inogona kuratidza magineti zvinoenderana nesimbi yavanosanganiswa nayo. Aya alloys akasanganiswa nesimbi huru pamwe chete nezvinhu zvakasiyana-siyana zvekutevera.
Muchokwadi, tungsten inogona kushandiswa kugadzira akawanda alloys anogona kunge aine akasiyana magineti.
Semuenzaniso, tungsten simbi ine magineti nekuti ine simbi ine ferromagnetic iron. Izvi zvinewo huwandu hwevanadium uye molybdenum pamwe chete ne8% tungsten.
Tungsten carbide inogonawo kuratidza magineti, zvichienderana nemamwe masimbi anoshandiswa mukuita alloying. Tungsten carbide inoda simbi yekubatanidza kuti isanganise zvakanaka uye kusarudzwa kwesimbi kunokanganisa maitiro ayo emagetsi. Kana cobalt kana simbi ikaiswa mualloy ipapo inenge iine magineti, kune rumwe rutivi kana nickel ikashandiswa zvino ichava magineti.
Zvinhu Zvinokanganisa Tungsten Magnetism
Pane zvinhu zvakawanda zvinokanganisa magineti etungsten. Zvinhu izvi zvinosanganisira:
Tembiricha:Ichi chinhu chinotsamira pamutemo waCurie uyo unoti iyo magineti susceptibility yeparamagnetic material inopesana netembiricha. Kuwedzera kwekushisa kunoderedza magnetic susceptibility, izvo zvinoguma nekuderera kwemagineti mhinduro. Kupisa kwakadzika kune zvinopesana uye kunowedzera magineti e tungsten.
Inoshandiswa magnetic field:Iyo inoshandiswa magineti inokanganisa kutaridzika kwemaerekitironi mu tungsten. Simba remagineti rakasimba rinobvumira chinhu kuti chiwane kwechinguva chisina simba remagineti chinonyangarika kana magineti yabviswa.
Binder content:Kune tungsten alloys, binder zvinhu zvinoshandiswa kunyungudutsa zvinhu zvakasiyana. Semuyenzaniso, cobalt inozivikanwa kuvandudza zvivakwa izvi, nepo nickel ichivharira iyo yatove mishoma mhedzisiro, ichiita iyo element isiri-magnetic.
Kuumbwa:Kunyatsorongeka kwechinhu ichi kunobata zvakananga magineti e tungsten pamwe nenhamba yemaerekitironi asina kupetwa uye kuvapo kwe dipoles uye kurongeka kwavo.
Zvishandiso uye Kukosha kweTungsten
Sechinhu chakakosha chesimbi,
tungstenine huwandu hwakawanda hwekushandisa uye kukosha muminda yeindasitiri nesainzi uye tekinoroji. Izvi zvinotevera mashandisirwo makuru uye kukosha kwe tungsten:
1. High-temperature alloy kugadziraTungsten ine yakakwirira yekunyungudika uye yakakwirira simba zvivakwa, zvichiita kuti ive chinhu chakakosha mukugadzirwa kweyepamusoro-tembiricha alloys. Aya alloys epamusoro-tembiricha anowanzo shandiswa mumhepo, aeroengines, simba renyukireya uye maindasitiri emakemikari, uye anogona kumira zvakanyanya kupisa kwakanyanya uye kumanikidza nharaunda.
2. Zvishandiso zvekucheka uye mabrasivesNekuda kwekuoma kwakanyanya uye kupfeka kuramba kwe tungsten, tungsten alloys anowanzoshandiswa mukugadzira maturusi ekucheka, madhiri, mabrasives uye maturusi ekukuya. Zvishandiso izvi zvinoita basa rakakosha mukugadzirisa simbi, migodhi uye mamwe maindasitiri minda.
3. Electronics indasitiri
Tungsten inoshandiswa zvakanyanya muindasitiri yemagetsi kugadzira maelectrodes, vacuum chubhu, zvigadzirwa zvemagetsi uye semiconductor zvishandiso. Iyo yakakwirira yekunyungudika uye kugadzikana kunoita kuti ive imwe yezvakanakira zvigadzirwa zvemagetsi zvigadzirwa.
4. Munda wezvokurapa
Tungsten alloys anoshandiswa kugadzira michina yekurapa, zvidziviriro zvemwaranzi uye michina yeradiotherapy. Yayo yakakwirira density uye radiation yekudzivirira zvivakwa inoita kuti ive yakakosha application munharaunda yekurapa.

5. Munda wesimba renyukireya
Tungsten inoshandiswa zvakanyanya mumunda wesimba renyukireya kugadzira maitiro ekudzora zvinhu zvema nyukireya reactor uye zvimwe zvigadzirwa zvesimba renyukireya. Kuwanda kwayo uye kunyungudika kwayo kunoita kuti ive sarudzo yakanaka yezvigadzirwa zvesimba renyukireya.
6. Zvimwe zvikumbiro
Tungsten inoshandiswawo kugadzira high-density alloys, aerospace devices, optical lenzi, zvikamu zvemotokari, nezvimwewo. Kushandiswa kwaro munzvimbo dzakasiyana-siyana dzemaindasitiri kwakabatsira zvikuru.
Muchidimbu, tungsten, sechinhu chakakosha cheinjiniya, ine yakasarudzika yemuviri uye makemikari zvimiro, izvo zvinoita kuti iite basa rakakosha muminda yakawanda. Kuoma kwayo kwepamusoro, kunyungudika kwakakwirira, kuramba kwecorrosion uye kugadzikana kwedimensional kunoita kuti ive imwe yezvinhu zvakakosha mundima dzakasiyana dzeindasitiri nesainzi. Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, iyo tungsten ndima yekushandisa icharamba ichikura nekuita mipiro yakakura mukufambira mberi nekusimudzira nzanga yevanhu.
