Kodi sintering metal powder ndi chiyani?

Mu Metallurgy,Njira yopangira ufa wa Metallurgykapena ntchito ngati zopangira kulenga zitsulo, zipangizo gulu, ndi zinthu zosiyanasiyana pambuyo kupangidwa ndi sinterized. Powder metallurgy, yomwe ndi gawo laling'ono laufa zitsulo sintering, zimagwirizana ndi kupanga zoumba. Zotsatira zake, ng'anjo zingapo zopangira zitsulo za ufa zitha kugwiritsidwanso ntchito popanga zida za ceramic.

1. Kukonzekera kwa zopangira ufa. Njira zomwe zilipo kale mphero zitha kugawidwa m'magulu awiri: njira zamakina ndi njira zakuthupi. Njira zamakina zitha kugawidwa kukhala: kuphwanya makina ndi atomization; Njira zakuthupi ndi zamankhwala zimagawidwa mu njira ya electrochemical corrosion, njira yochepetsera, njira yamankhwala, njira yochepetsera-mankhwala, njira yoyika mpweya, njira yoyika madzi ndi electrolysis. Pakati pawo, njira yochepetsera, njira ya atomization ndi njira ya electrolysis imagwiritsidwa ntchito kwambiri.

2. Ufa umapangidwa kukhala wopanda kanthu ndi mawonekedwe omwe akufuna. Cholinga cha kuumba ndi kupereka chosowekapo mawonekedwe ndi kukula, ndi kupereka kachulukidwe ena ndi mphamvu. Njira zopangira zimagawika m'magulu opangira mphamvu komanso osakakamiza. Kuwumbidwa kwamphamvu kumagwiritsidwa ntchito kwambiri popanga kuthamanga.

3. billet sintering. Njira yofunika kwambiriufa wa metallurgy sinteringteknoloji ya ng'anjo ikukula. The billet yaiwisi akhoza sintered atapangidwa kuti apereke anafuna makina ndi thupi makhalidwe. Unit sintering ndi multi-system sintering ndi magulu awiri a sintering. Kutentha kwa sintering ndikotsika kuposa kusungunuka kwachitsulo ndi aloyi komwe kumagwiritsidwa ntchito popanga sintering yolimba ya unit system ndi multi-element system. The sintering kutentha kwa madzi gawo sintering wa Mipikisano chigawo chimodzi kachitidwe nthawi zambiri apamwamba kuposa kusungunuka wa fusible chigawo chimodzi koma kutsika kuposa kusungunuka kwa refractory chigawo chimodzi. Pali njira zapadera zopangira sintering monga kuwombera kotayirira, kusungunula konyowa, ndi kukanikiza kotentha kuwonjezera pa sintering wamba.
4. kutsatira mankhwala mankhwala. Kutsatira sintering, njira zosiyanasiyana processing angagwiritsidwe ntchito kutengera zofuna za chomaliza. monga Machining, kutentha mankhwala, electroplating, kumaliza, ndi zina zotero. Kuphatikiza apo, m'zaka zaposachedwa, zida zopangira ng'anjo za ufa zakhala zikugwiritsidwa ntchito pogwiritsa ntchito kugudubuza, kufota, ndi njira zina zatsopano, ndipo zotsatira zabwino zapezeka.
