Oxidation kariya na jan karfe kumfa a sintering tanda

Dalilin da yasakumfa tagullabaya oxidize
Kumfa Copper wani abu ne mai ƙura da aka yi daga cakuda tagulla na ƙarfe da kuma wakili mai kumfa, wanda ake gasa kuma ana fadada shi a yanayin zafi mai yawa. A cikin tanderun tanderu, kumfa na jan karfe yana da sauƙi don oxidize a cikin iska saboda kwayoyin oxygen na iya shiga cikin kumfa ta cikin kumfa kuma su amsa tare da jan karfe don samar da jan karfe oxide. Duk da haka, akwai adadi mai yawa na iskar gas a cikin kumfa na jan karfe, kuma waɗannan ramukan gas na iya fitar da kwayoyin oxygen daga cikin kumfa, don haka gane tasirin rashin iskar oxygen.
Matakan Kariya
Ko da yake akwai babban adadin iskar gas a cikinkumfa tagulla, idan yanayin da ke cikin tanderun bai dace ba har yanzu zai haifar da oxidation. Sabili da haka, a cikin tanderun da aka yi amfani da shi, don kare kumfa na jan karfe daga oxidation, ana buƙatar ɗaukar matakai masu zuwa:
1. Gudanar da yanayi mai gudana: Sarrafa yanayin redox a cikin tanderun sintering ta hanyar daidaita ƙarfin redox na thermal. Daga cikin su, yanayin oxidizing zai hanzarta iskar oxygen da kumfa na jan karfe, don haka ya zama dole don rage abun ciki na iskar oxygen da ƙara yawan abun ciki na rage iskar gas.
2. Surface shafi m wakili: shafi Layer na m wakili a kan surface nakumfa tagullaiya yadda ya kamata tsayayya hadawan abu da iskar shaka. Abubuwan kariya da aka fi amfani da su sune man silicon, sintered carbon foda, aluminum oxide da sauransu. Daga cikin su, alumina na iya samar da wani Layer na barga alumina fim don hana ƙarin oxygen dauki.
Dalilin da ya sa kumfa na jan ƙarfe ba ya yin oxidize a cikin tanderun da ke daɗaɗɗa shi ne cewa akwai adadi mai yawa na iskar gas a cikinsa, wanda zai iya fitar da kwayoyin oxygen daga cikin kumfa. Don kare kumfa na tagulla, ya zama dole don sarrafa yanayin da ke gudana a cikin tanderun da aka yi amfani da shi da kuma rufe samansa tare da wakilai masu kariya da sauran matakan.
