(Mpira wa Hi3n4Opangidwa ndiWntrustek)

Kuchimwa ndi njira yomwe zinthu zoweta zimaphatikizika ndikutenthetsedwa kuti azipanga zochuluka. Nthawi zambiri, njirayi imachitika pansi pa zida zosungunuka. Tinthu tating'onoting'ono timakhala tikuyandikira pafupi kwambiri panthawi ya uchimo, ndipo kuteteza kwa kutentha kumalimbikitsa kuloza maatomiki ndi kusiyana pakati pa tinthu, kumapangitsa kuti muchepetse komanso kupanga kapangidwe kake. Zitsulo, magwiritsidwe ntchito, ndi ma centimini nthawi zambiri amapangidwa ndi kuchimwa.

Njirayi yotchedwa "yotentha mwachizindikiro," kapena "m'chiuno," imagwiritsidwa ntchito polimbikitsa machitidwe ndi kukhulupirika kwa zida. Imaphatikizapo kugwiritsa ntchito nthawi yomweyo kugwiritsa ntchito kuthamanga kwambiri komanso kutentha kwa zinthu. Mumpu ya m'chiuno, mpweya wa bart umagwiritsidwa ntchito polimbana ndi zinthu zomwe zimatenthedwa kuti zitheke. Kupsinjika kwambiri komanso kutentha kwambiri kumagwirira ntchito limodzi kuti achotse zolakwika zamkati, monga pores kapena voids, ndikuumirira zida za metallourgy kukhala zigawo zowiritsa.

Kuchimwa (m'chiuno: Khotu lotentha kwambiri, Sps: Spark Plasma wochimwa, HP: Phula la Plasmal) limakhala ndi mwayi wochepetsa kutentha kwa kuchimwa komanso kwaulere. Zotsatira zake, ndizotheka kupeza mitengo yazidziwitso yomwe ili pafupi ndi kachulukidwe kake pomwe nthawi yomweyo imawongolera kuwongolera microstruction pa micramics.

Zoyambira za kuchititsa chidwi
Kugwiritsa ntchito zovuta pazinthu nthawi yomweyo kuchokera mbali zonse kumadziwika kuti kuphatikizidwa kwa chipongwe. Izi zimatheka poyika thumba kapena chidebe chosindikizidwa ndikugwiritsa ntchito zopanikiza kwambiri pogwiritsa ntchito sing'anga yamadzi, nthawi zambiri amakhala gasi ngati Argon. Anisotropy ndi zolakwika sizingatheke pakavuta zimagwiritsidwa ntchito molunjika kuyambira pomwe izi zikutsimikizira mosafanana.

Mfundo Zovuta Kwambiri
Njira yopangidwira kutentha kwa Inostratic (m'chiuno) imagwira ntchito mokakamizidwa kwambiri mbali zonse kuti muchepetse zida zonse, makamaka zapamwamba. Chifukwa chopanga ceramic apamwamba kwambiri okhala ndi makina osintha, mafuta, ndi katundu wamagetsi, njirayi ndiyofunikira.

Njira zokutira kutentha kotentha:

Kupanga kwa Thupi la Thupi → Thupi lobiriwira lomwe limayikidwa mchipinda chosindikizidwa

Allistek adatulutsa zigawo zambiri za m'chiuno si3n4, kuno, timakakamiza pakuyambitsaMpira wa Hi3n4.

Kukakamiza Kwazovuta (m'chiuno) siyicon nitride mipiraali m'gulu la njira zapamwamba kwambiri zopangira zida za ulicon ninride. Ndizotheka kuti ntchito yake igwire ntchito pokhazikitsa zinthu zomwe zida zachikhalidwe sizothandiza. Chifukwa cha mawonekedwe ake okhazikika, imatha kupirira kugwedezeka kwamafuta ndikusunthika pakusintha kwa kutentha. Chifukwa sichinthu chamatsenga komanso chosagwira, chitha kugwiritsidwa ntchito ndi zida zowoneka bwino kapena zamagetsi, ndipo cholumikizira cholunjika chochepa chimatsimikizira ntchito yosalala yothamanga kwambiri. Mpira wa deramu ndi wodalirika ngati umagwiritsidwa ntchito m'magulu a vacuum, omwe amadziwika ndi mankhwala, kapena amathama popanda mafuta.

Zabwino za mipira ya m'chiuno si3n4:

• Kuvala zosagwirizana

• Kulemera,

• Kusunga Magetsi

• Mphamvu yapamwamba kwambiri.

• Kusinthidwa kwakukulu. Kuthetsa zofooka kapena zamkati, makamaka chifukwa, titha kubisalira bwino.

• Kulimbitsa thupi kwambiri. Zinthu zam'madzi ndizopanda phokoso. Ndi mphamvu yayitali, pomwe kudalira mwamphamvu, ming'alu ndi zolakwika zimachitika zochepa. Titha kunena kuti kuvuta kwambiri kumatha kupewa kulephera kowononga.

Powombetsa mkota, kukanikiza kotentha kwamphamvu ndi njira yosinthira yamasewera m'munda wamakamizidwe omwe amatsegula mwayi watsopano wa mafakitale osiyanasiyana ndipo amapereka njira yabwinoko yakuthupi. Kuti mupange ceramics omwe amakwaniritsa zofunikira kwambiri, njira ya m'chiuno imayang'anira kutentha, kukakamizidwa, ndi nthawi. Imakhala ndi gawo lofunikira pakukula kwa zinthu za deramic ndi ntchito zawo m'minda yofunika. Ponena za mipira ya m'chiuno, pofunikira kuthamanga kwambiri, osakhalitsa, oletsa magetsi, ndi malo ena ogwiritsa ntchito, amasewera ndi kudalirika kwapadera komanso chitetezo.
