Ka'idar Karfe Foda Sintering

Hanyar karafa ta foda ita ce a sanya danyen kayan da ake amfani da su a ciki su zama foda, sannan a hada su daidai gwargwado, sannan a daka su da karfi su zama wata siffa. Ana sanya waɗannan tubalan foda a cikin yanayi mai rahusa, kamar hydrogen, mai zafi, da sintered don samar da gami. Wannan ita ce hanyar ƙarfe da ta sha bamban da hanyoyin simintin gyaran kafa na baya.

Sintering kamar yadda aka ambata a nan za a iya kawai bayyana a matsayin inganta agglomeration na karfe hatsi ta mataki na matsa lamba da zafi. Muna amfani da wani adadin matsa lamba zuwa foda tare da abun da ke ciki don ƙaddamar da shi. A yanayin zafi mai yawa, foda da ke kusa da juna suna manne da juna kuma a hankali suna cika ɓangarorin don samar da gami mai girma. Zazzabi mai zafi a wannan lokacin shine yanayin zafi na narkewar ƙarancin ƙarancin narkewa a cikin abubuwan haɗin gwal. Sabili da haka, an yi amfani da alluran ingot a cikin zafin jiki a ƙasa da ma'anar narkewa na dukkan abubuwan foda. Wannan hanya tana kama da haɗa hanyoyin biyu na narkewa da simintin gyare-gyare, kuma kaddarorinsa suna kusa da na simintin ƙarfe. Amma daga ra'ayi na metallographic, ya kamata ya zama reshe na simintin ƙarfe.

Ana samar da carbide da aka yi da siminti ta wannan hanyar ƙarafa ta foda. Yawanci, ana amfani da foda irin su tungsten, carbon, cobalt, titanium, da cerium don haɗa batch, sa'an nan kuma ana dannawa kuma a yi su don samar da gami. Don haka, samfurin wannan aikin ƙarfe kuma ana kiransa siminti carbide ko siminti carbide. A cikin 'yan shekarun nan, hanyoyin ƙarfe na foda sun haɓaka da sauri. Carbide, gami da ke ƙunshe da mai, lambobin lantarki, ƙafafun niƙa na lu'u-lu'u da ƙarfe, da samfuran ƙarfe na musamman na ado ana kera su ta amfani da wannan hanyar ƙarfe ta foda.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
