Nhanganyaya yeLanthanum Tungsten (Mutemo)
Lanthanum Tungsten, inowanzopfupikiswa seLawWkana kumiririrwa seW{{0}La₂O₃, haisi musanganiswa wemakemikari wakasiyana asi kuti adispersion{{0}yakasimbiswa alloy. Icho chinhu chakaumbwa chinosanganisira tungsten (W) simbi matrix yakapinzwa neakanaka, yunifomu dispersion yelanthanum oxide (La₂O₃) zvimedu, zvinowanzo sanganisira 1-5% yehuremu hwese.
Nyaya iyi ndeyekirasi yezvigadzirwa zvepamusoro zvinozivikanwa seoxide-dispersion-yakasimbiswa (ODS) alloys. Kuiswa kwelanthanum oxide nanoparticles kunosimudzira zvimiro zve pure tungsten, zvichiita kuti ive yepamusoro yekuda kukwirisa-tembiricha yekushandisa.
Zvinhu uye Zvakanakira
Iwo ekutanga ekuvandudza Lanthanum Tungsten anopa pamusoro petungsten yakachena ndeaya:
Superior High-Temperature Stability and Creep Resistance:
Iwo akapararira La₂O₃ particles akanyatsogadzikana uye anoita sezvipingamupinyi zvepanyama zvinopinza miganhu yezviyo uye kuparadzaniswa mukati me tungsten matrix. Izvi zvinodzivirira zvinhu kubva pakuremara pasi pemichina yekuremerwa pakupisa kwakanyanya (kazhinji pamusoro pe2000 degree), chiitiko chinozivikanwa se "creep."
Yakakwira Recrystallization Temperature:
Yakachena tungsten inova brittle mushure mekudzokororazve pakupisa kwakanyanya. Iyo lanthanum oxide particles inodzivisa kukura kwezviyo, kusimudza tembiricha panoitika recrystallization. Izvi zvinobvumira Mutemo kuti uchengetedze ductility uye simba remagetsi kwenguva yakareba pasi pekunetseka kwekupisa.
Enhanced Thermionic Emission Properties:
Lanthanum ine basa rakaderera pane tungsten. Kuvapo kwemaatomu elanthanum pamusoro pe electrode kunoderedza simba rinodiwa kuti maerekitironi apukunyuke (kureva, kunoderedza basa rebasa). Izvi zvinoguma nekukwira kwakanyanya kwemagetsi emission emission, izvo zvakakosha kune maerekitironi masosi.
Yakavandudzwa Mechanical Simba uye Kusimba:
Iyo yekuparadzira inosimbisa meshini inowedzera zvakanyanya kuoma, kusimba simba, uye kuramba deformation mukamuri uye tembiricha yakakwira zvichienzaniswa netungsten yakachena.
Applications
Nekuda kwezvimiro zvayo, Lanthanum Tungsten inonyanya kushandiswa mu:
Electron Microscopy uye Spectroscopy:
Icho chinhu chinofarirwaelectron gun cathodes (filaments)mumidziyo yakaita seScanning Electron Microscopes (SEMs) uye Transmission Electron Microscopes (TEMs). Kubuda kwayo kwepamusoro ikozvino uye kugadzikana kunopa kupenya, kwakabatana matanda erekitironi uye hupenyu hurefu hwesevhisi pane yakachena tungsten filaments.
Welding uye Plasma Arc Kucheka:
Mutemo unoshandiswaasiri{{0}maelectrodhi anobatikamuTIG (Tungsten Inert Gas) welding uye mazhenje eplasma. Kupokana kwayo kune tembiricha yakakwira uye deformation inobvumira kugadzikana kwearc kuumbwa, kuita zvirinani pamhepo yakakwira, uye hupenyu hurefu kusati kwaitika electrode tip degradation.
Yepamusoro{{0}Zvikamu zveFurnace:
Inoshandiswa kugadzira zvinhu zvekudziisa, zvivharo zvemwaranzi, uye zvivakwa zvinotsigira muvacuum nepamusoro-mafurini ekupisa uko kunonyanya kudzivirira kupisa uye kusimba kwechimiro chakakosha.
Aerospace uye Nuclear Fusion:
Inoferefetwa kuti ishandiswe muzvikamu zvakakosha zveinjini dzemuchadenga uye seplasma-zvinhu zvinotarisana neplasma (semu, zvekutsaudzira) mumagetsi emusanganiswa wenyukireya, apo zvinhu zvinofanirwa kushingirira kupisa kwakanyanya uye kuyerera kwechidimbu.
Muchidimbu, Lanthanum Tungsten ndeyepamusoro-inofambisa basa, yakapararira{1}}yakasimbiswa alloy inosanganisa intrinsic high melting point uye density ye tungsten nekusimudzirwa kukuru-kusimba kwetembiricha, kugadzikana, uye kuburitsa maerekitironi, zvichiita kuti ive chinhu chakakosha kumamiriro emagetsi epamusoro, vacuum nharaunda.
