Kodi ukadaulo woumba jakisoni wa Metal powder ndi chiyani

Ndi chiyaniMetal ufa jakisoni akamaumbaluso?Micro ufa jekeseni akamaumba luso Ochiritsiraufa jekeseni akamaumba ndondomeko (INE),pmankhwala owder metallurgyzomwe zingathe kukonzedwa ndi kupangidwa zimakhala zochepa pa kulemera kwa 3 mpaka 509. M'zaka zaposachedwa, chifukwa cha kugwiritsa ntchito teknoloji yowonjezereka kwambiri, zakhala zotheka kugwiritsa ntchito nkhungu zazing'ono zolondola kuti zigwiritse ntchito bwinomim zitsulo jekeseni akamaumba ndondomekokupanga zinthu zovuta ku makina ndi zinthu zomwe zimakhala zovuta komanso zazing'ono ndipo sizingathe kusinthidwa kapena kusinthidwa pamwamba. Iyi ndi njira ya micro-MIM (micro-MIM). Zogulitsa zomwe zimapangidwa ndi njira ya Micro-MIM sizomwe zili gawo lalikulu lazinthu za njira ya MIM pakadali pano, koma njirayo imatha kuthana ndi zinthu zovuta kukonza, mawonekedwe ovuta komanso magawo omwe safunikira kukonzedwa kwamakina, chifukwa chake mawonekedwe ake akuyembekezeka kukula mwachangu. Kuchokera pamalingaliro a microMtengo wa MIMndi zopangira zomwe zimagwiritsidwa ntchito pazogulitsa, kukula kwazinthu zake kumakhala kosakwana 1mm. N'zovuta kusintha kulondola kwa dimensional ndi mapeto a pamwamba pa zinthuzo pogwiritsa ntchito luso lamakono lokonzekera. Choncho, kuti akwaniritse zofunikirazi, m'pofunika Gwiritsani ntchito fineness inayake ya ufa. Ufa womwe umagwiritsidwa ntchito mu jakisoni wachitsulo wa mim uli ndi kukula kwa tinthu pafupifupi 10 m'mimba mwake, koma lamulo la Micro MIM limafuna kugwiritsa ntchito ufa wokhala ndi tinthu tating'ono pafupifupi 3 m. Pamwamba pa sintered mankhwala a yaying'ono MIM opanda kanthu akapezedwa pogwiritsa ntchito ufa wabwino wotero akhoza kufika RaO 0.25m, pamene ochiritsirazitsulo jekeseni akamaumba mbaliakhoza kungopeza RaO 1.2m. Ufa wachitsulo wokhala ndi tinthu tating'ono pafupifupi 39m ukhoza kupangidwa pogwiritsa ntchito madzi othamanga kwambiri pafupi ndi 1000kg/cm2 kuti akhudze mtsinje wosungunuka wachitsulo, ndiko kuti, njira yothamanga kwambiri yamadzi. Ukadaulo uwu wapangidwa ndi mafakitale.
