Tungsteninonyanya kukodzera sezvinhu zvezvikamu zvakasimbiswa zvikuru zvemudziyo wakavhara inopisa fusion plasma, iyo iri iyo simbi ine nzvimbo yakakwirira yekunyunguduka.Zvisinei, kuipa kwayo, kushata kwayo, uko pasi pekunetseka kunoita kuti iite zinyekenyeke uye ive nyore kukuvara.Iri bhuku, rakawedzera kusimba musanganiswa zvinhu zvino rakagadzirwa naMax Planck Institute yePlasma Fizikisi (IPP) kuGarching.Inosanganisira homogeneoustungstenwith coatedtungsten wayaembedded.Ongororo yezvinogoneka ichangobva kuratidza kukosha kwekomboni itsva.

Chinangwa chetsvakiridzo yakaitwa paIPP kugadzira gwenya remagetsi iro, sezuva, rinowana simba kubva mukusanganiswa kweatomic nuclei.Mafuta anoshandiswa ndeye low-density hydrogen plasma.Kubatidza moto wekusanganisa plasma inofanirwa kuvharirwa muminda yemagineti uye inopisa kusvika pakupisa kwakanyanya.Mukati me100 miriyoni madhigirii anowanikwa.Tungstenisimbi inovimbisa zvakanyanya sezvinhu zvezvikamu zvinosangana zvakananga neplasma inopisa.Izvi zvakaratidzwa nekuongorora kwakadzama paIPP.Dambudziko kusvika ikozvino risati ragadziriswa, zvisinei, kwave kuri brittleness yezvinhu:Tungsteninorasikirwa nekuoma kwayo pasi pemamiriro ekugadzira magetsi.Kushushikana kwepanzvimbo - kushushikana, kutambanudza kana kudzvanywa - hakugone kubviswa nezvinhu zvishoma zvinopa nzira.Mitswe inoumba panzvimbo: Zvikamu saka zvinobata zvakanyanya kune kuwandisa kwenzvimbo.

Ndosaka IPP yakatsvaga zvimiro zvinokwanisa kugovera kusawirirana kwenzvimbo.Fibre-reinforced ceramics akashanda semhando: Semuyenzaniso, brittle silicon carbide inogadzirwa kashanu kusimba kana yakasimbiswa nesilicon carbide fiber.Mushure mezvidzidzo zvishoma zvekutanga IPP musayendisiti Johann Riesch aifanira kuongorora kana kurapwa kwakafanana kuchigona kushanda nesimbi ye tungsten.

Danho rokutanga raiva rokubudisa mashoko matsva.Atungsten matrix yaifanirwa kusimbiswa neshinda refu yakavharwa yaisanganisira extrudedtungsten wayadzakaonda sebvudzi.Waya, pakutanga dzaida kupenyafilamentsyemarabhu emwenje, kwainopihwa neOsram GmbH.Zvinhu zvakasiyana-siyana zvekuzviputira zvakaongororwa paIPP, kusanganisira erbium oxide.Iyo yakazara yakazaratungsten fibersaibva abatanidzwa pamwe chete, akabatana kana kuti akarukwa.Kuzadza mikaha pakati pewaya ne tungsten Johann Riesch nevamwe vaaishanda navo vakabva vagadzira hurongwa hutsva pamwe chete neChirungu indasitiri mubatsiri Archer Technicoat Ltd. Nepo tungsten workpieces kazhinji akatsikirirwa pamwe chete kubva simbi poda pakupisa kwepamusoro uye kumanikidzwa, zvimwe zvakawanda. nzira yakapfava yekugadzira komboni yakawanikwa: Thetungsteninoiswa pawaya kubva musanganiswa wegasi nekuisa kemikari maitiro pakudziya kuri pakati nepakati.Aka kaive kekutanga kutitungsten-fiber-yakasimbiswa tungstenrakagadzirwa zvinobudirira, nemhedzisiro yaidiwa: Kutyoka kwekuomarara kwekomboni itsva kwakange kwatopetwa katatu maererano nefibreless tungsten mushure mebvunzo dzekutanga.

Danho rechipiri raive rekuferefeta kuti izvi zvinoshanda sei: Chinhu chakakosha chakaratidza kuve kuti mafiber bhiriji anotsemuka mumatrix uye anogona kugovera simba rinoshanda munharaunda mune izvo.Pano kupindirana pakati pefibers uye tungsten matrix, kune rumwe rutivi, inofanira kuva isina simba zvakakwana kuti ipe nzira kana kuputika kuchiita uye, pane imwe, kuva yakasimba zvakakwana kuendesa simba pakati pefibers uye matrix.Mukupeta bvunzo izvi zvinogona kucherechedzwa zvakananga kuburikidza neX-ray microtomography.Izvi zvakaratidza kushanda kwekutanga kwezvinyorwa.

Sarudzo yekubatsira kwechinyorwa, zvisinei, ndechekuti iyo yakakwidziridzwa kuoma kunochengetwa kana ichinge yaiswa.Johann Riesch akaongorora izvi nekuferefeta masampuli akange akaputirwa nekutanga kurapwa kwekupisa.Kana masampula akaiswa pasi pemakroskopu erekitironi, kutambanudza nekukotamisa zvakare mune iyi nyaya yakagadziridzwa zvinhu: Kana iyo matrix ikatadza kana yakatsikiswa, mafiibhi anokwanisa kubhuroka kutsemuka kuri kuitika nekudzimisa.

Nheyo dzekunzwisisa uye kugadzira zvinyorwa zvitsva zvinogadziriswa.Masamples ave kuzogadzirwa pasi pemaitiro akagadziridzwa maitiro uye ane optimized interfaces, ichi chiri chinhu chinodiwa pakugadzirwa kwakakura.Izvo zvinyorwa zvitsva zvinogona zvakare kufarira kunze kwemunda wekutsvagisa fusion.
