Karfe Kumfa - karfe da ke numfashi

Saboda tsarinsa na musamman, yana da kaddarori na musamman ta fuskoki da dama. A matsayin kayan aiki na tsari, an kwatanta shi da nauyin nauyi da ƙayyadaddun ƙayyadaddun ƙarfi; a matsayin kayan aiki, yana da nau'o'in kayan aiki na jiki irin su porous, vibration damping, damping, sauti-ƙarar sauti, sautin murya, zafi mai zafi, tasirin tasirin makamashi, kariya ta lantarki da sauransu.
Karfe kumfaana shirya shi ta hanyar hanyar ƙarfe na foda da hanyar lantarki, na farko ta hanyar ƙara wakili mai kumfa zuwa narkakken ƙarfe don samar da ƙarfen kumfa; na karshen ta hanyar electrodeposition a kan kwarangwal na kumfa polyurethane da aka kwafi zuwa karfen kumfa.
Hanyar ƙarfe na foda don yin karfen kumfa, ana ƙara shi zuwa wakili mai busa foda (kamar NH4Cl), yana lalata wakili mai hurawa, yana barin pores. Ƙarfe na kumfa tare da pores na yau da kullum da porosity kamar yadda 95% za a iya yin su ta hanyar jigilar kwayoyin halitta, ciki har da kayan kumfa tare da karafa da gami kamar Cu, Ni, NiCrFe, ZnCu, NiCu, NiCrW, NiFe, da sauran karafa da gami kamar kwarangwal. Karfe electrochemically ajiya a kan porous jiki ne sintered ta yadda da ajiya abubuwan da aka haɗa gaba daya, da kuma ƙarfi ne har zuwa da ake bukata sosai porous karfen kumfa tare da high porosity, wanda za a iya cika da ƙarin abubuwa kamar catalysts da electrolytes a ciki. amfani.
