Kodi teknoloji ya powder metallurgy ndi chiyani?

Ufa zitsulo luso linayamba kugwiritsidwa ntchito mu United States mu 1870. Iwo ntchito ufa zitsulo monga zopangira, ndiyeno mbamuikha copper-kutsogolera zitsulo aloyi mayendedwe kuzindikira kudziona lubricating luso la kubala, ndipo anapanga mbali zosiyanasiyana ndi zigawo zikuluzikulu mwa kukanikiza. ndi kuimba.Njira zamakono zamakono za ufa zimamveka zosadziwika kwa aliyense, koma ngati nditatha kufotokoza kwanga , zidzakhala zosavuta kuti mumvetse.

Njira yoyambira yaukadaulo waukadaulo waufa
Chinthu chachikulu ndi ufa wachitsulo wabwino, ndiye ufawo umawonjezeredwa ku nkhungu yofunikira, ndiyeno chitsanzocho chimapangidwa ndi (jekeseni) kapena kupanikizika, ndipo pamapeto pake gawo lofunidwa ndi zotsatira zake zikhoza kupezedwa ndi sintering.Zigawo zina zimafunikira pambuyo pokonza.

Kodi pali kusiyana kotani kwa magawo a MIM ndi PM powder metallurgy?
1: Kuumba jekeseni wa zitsulo za ufa
Powder metallurgy jakisoni anabadwira ku California mu 1973, wotchedwa MIM.Ndi mtundu watsopano wa luso zitsulo akamaumba ufa anatulukira ndi kaphatikizidwe pulasitiki jekeseni akamaumba luso ndi munda wa ufa zitsulo.The ufa zitsulo jekeseni akamaumba ndondomeko ali pafupi ndi luso zitsulo ufa.Choyamba, ufa wolimba ndi binder organic zimasakanizidwa mofanana, ndiyeno zimatenthedwa ndi pulasitiki pa kutentha kwakukulu kwa madigiri 150.Zida zopangira jekeseni zimagwiritsidwa ntchito pobaya nkhungu muzitsulo, kenako zimalimba ndi mawonekedwe.Njira yowola imachotsa chomangira chopanda kanthu, ndipo pomaliza, monga zitsulo za ufa, mbali zolondola zimapangidwa kudzera mu sintering.

2: Kukanikiza zitsulo za ufa
Powder metallurgy compression molding ndikudzaza nkhungu ndi ufa ndi mphamvu yokoka, ndikuyitulutsa ndi kukakamiza kwa makina.Ndi imodzi mwazogwiritsidwa ntchito kwambiri m'mafakitale ogwira ntchito.Kusindikiza kwachitsulo chosindikizidwa ndi chitsulo chozizira, kukanikiza kozizira kwa isostatic, kukanikiza kotentha kwa isostatic, ndi kukanikiza kotentha zonse zikupanga atolankhani.Komabe, chifukwa ukhoza kukanikizidwa mmwamba ndi pansi mbali zonse ziwiri, zigawo zina zovuta kwambiri sizingapangidwe kapena zikhoza kupangidwa kukhala zopanda kanthu.

Magawo ambiri amagwiritsa ntchito jekeseni kapena kuponderezana, ndipo gawo lomaliza lidzakhala losiyana.Ngati simutha kusiyanitsa bwino, musazengereze kulumikizana nafe Jingshi New Materials kuti mukambirane.
