Ufa zitsulo sintering kuumitsa ndi ndondomeko kuphatikiza sintering ndi kutentha mankhwala, ndiko kuti, pambuyo zinthu zina sintered ndi mofulumira utakhazikika, martensite (nthawi zambiri> 50%) kwaiye mu dongosolo metallographic, kotero kuti zinthu ndi kupanga Play a ntchito yothandiza kwambiri komanso kuwongolera bwino chuma.
Ubwino wa sintering harding:
1. Njira yothandizira kutentha ikhoza kuchotsedwa
2. Pewani kuipitsidwa kwa mafuta ozimitsa
3. Osavuta kupsa mtima mumlengalenga
4. Chepetsani kusintha kwa mankhwala
5. Konzani kuwongolera kukula
6. Kupititsa patsogolo ntchito zachuma
7. Kugwiritsa ntchito sinter kuumitsa
Powder metallurgy sintered zida zowumitsa nthawi zambiri zimagwiritsidwa ntchito popanga zida zapakati komanso zolimba kwambiri.Pakalipano, ndondomeko yowumitsa sinter imagwiritsidwa ntchito makamaka pazinthu zomwe zimakhala zovuta kuzimitsa chifukwa cha kukula ndi mawonekedwe.Monga zida zamagiya, ma synchronizer hubs, mfundo zooneka mwapadera kapena zokhala ndi mipanda yopyapyala ndi zida zina zamapangidwe.Mwachidule, chitsulo ofotokoza ufa zitsulo sinter kuumitsa ndi imodzi mwa njira zothandiza kwambiri m'malo ufa zitsulo kutentha njira mankhwala, ndi ubwino wake kuposa kuipa.Kusankha zipangizo zoyenera zopangira sintering ndi kuumitsa sikungangopewa zotsatira zoyipa za chithandizo cha kutentha ndi kuchepetsa mtengo, koma kumbukirani kuti mankhwalawo atatha kutentha ndi kuumitsa ayeneranso kutenthedwa nthawi, nthawi zambiri kutentha kwa pafupifupi 180 ° C.
