Maganin zafi na saman yana nufin tsarin magance zafi kawai saman Layer na simintin ƙarfe. Maganin zafi na saman yana kuma iya samun tsarin ƙarfe da ake buƙata da kaddarorin inji.
Hanyoyin da ake amfani da su na yanayin zafi da aka fi amfani dasu sune: induction dumama quenching, harshen wuta quenching, Laser zafi magani, lamba juriya dumama quenching, electrolyte quenching, bugun jini dumama zafi magani, da dai sauransu Ta hanyar surface zafi magani, simintin gyaran kafa da sauran karfe sassa na iya samun wani surface Layer. wanda ya dace da bukatun aiki.
Bayan da surface hardening Layer aka samu ta surface dumama da quenching, core na simintin gyaran kafa na iya har yanzu kula da asali microstructure da yi, ta yadda za a cimma m m aiki na inganta gajiya ƙarfi, inganta lalacewa juriya da kuma rike taurin. A lokaci guda, maganin zafin jiki na saman yana iya rage yawan amfani da makamashi kuma a lokaci guda rage raguwar lalacewa.
Ƙarƙashin ƙaddamarwa tsari ne na maganin zafi wanda ke amfani da tasirin zafi da aka haifar ta hanyar shigar da halin yanzu ta wurin aikin don dumama saman simintin, a cikin gida ko gaba ɗaya, sa'an nan kuma yin saurin sanyaya. Tushen ka'idodin dumama shigar da su sune: shigar da wutar lantarki, tasirin fata da tafiyar da zafi.
Halayen Ƙunƙarar Dumamawar Induction:
1) Induction quenching yana da superplasticity. Taurin saman kayan aikin shine 2-3 HRC sama da na quenching na yau da kullun. Bayan shigar da dumama da quenching, martensite na simintin gyare-gyare yana da ɗan ƙaramin ƙarfi kuma an tarwatsa carbides.
2) Juriyar lalacewa na simintin gyare-gyaren bayan shigar da dumama quenching ya fi na talakawa quenching.
3) Saboda saman workpiece yana da kyau cryptocrystalline martensite kuma akwai damuwa damuwa, ƙarfin gajiyar aikin yana inganta sosai.
4) The ingancin workpiece ne barga da nakasawa ne kananan.
5) Gudun dumama da sauri da ingantaccen thermal
6) High yawan aiki, sauki gane mechanized samar
