Hanyoyin Sintering Na Foda Metallurgy (foda karfe sintering)
Hanyoyin sinterin ƙarfe na foda sun haɗa da:
Foda karfeyana buƙatar jerin matakai na tsari irin su samar da foda, latsawa, sintiri, da kuma bayan aiki. Daga cikin su, foda metallurgy sintering ne mai high-zazzabi magani tsari cewa kara hadawa compacts ko sako-sako da foda jikin don inganta ƙarfi da sauran kaddarorin. Koyaya, saboda bambance-bambancen, hanyoyin sinadaren ƙarfe na foda suma an kasu kashi iri-iri.
1. Ruwa lokaci sintering
Idan akwai abubuwa biyu ko fiye a cikin ƙananan foda, ana iya yin sintirin a sama da wurin narkewa na wani sashi, don haka ƙaramin adadin ruwa ya bayyana a cikin ƙwayar foda yayin sintering.
2. Matsa lamba sintering
A lokacin sintering, ana amfani da matsa lamba ga jikin foda don inganta tsarin densification. Matsisintiriwani lokaci yana kama da matsi mai zafi, wanda shine tsari wanda ke haɗa nau'ikan foda da kuma ɓarke don samun samfuran kai tsaye.
3. Kunna sintering
A cikin tsarin karkatarwar, ana ɗaukar wasu matakan jiki ko na sinadarai don rage yawan zafin jiki da rage lokacin da ake yin ɓacin rai, yayin da aikin jikin da aka ƙera yana inganta da haɓaka.
4. EDM sintering
Lokacin da aka kafa jikin foda da dannawa, ana amfani da wutar lantarki kai tsaye da pulse don samar da baka tsakanin abubuwan foda don sintering; a lokacin sintering, matsa lamba a hankali ana amfani da shi a kan workpiece, kuma ana haɗuwa da matakai biyu na kafawa da sintiri.
Abubuwan da ke cikin da aka gabatar a sama sune hanyoyin haɗin foda na gama gari guda huɗu. Ta hanyar waɗannan hanyoyin sintering, ana iya kammala aikin ƙarfe na ƙarfe na foda da kyau. Domin, a cikin aikin foda metallurgy sintering, foda barbashi da jiki da kuma sinadaran tafiyar matakai kamar juna kwarara, diffusion, narkewa, da recrystallization, ta yadda foda ya kara da yawa da kuma wasu ko duk daga cikin pores da aka kawar.
