Izinzuzo ze-silicon carbon alloy

Ukusebenzisa i-silicon carbon alloy ukuxazulula insimbi eluhlaza encibilikisiwe ye-grey cast iron kungashintsha kakhulu izici zekristalu yensimbi encibilikisiwe, kunciphise umkhuba womlomo womlotha futhi kususe umlomo ophikisana nomlotha. Ukuthambekela kwesango lomlotha ukuhlehlisa isango lomlotha kuhlobene namandla okukhiqiza i-nuclear ye-graphite ehlanzekile. Kungazwakala sengathi ingxubevange ye-silicon carbon inomsebenzi wokudala wesixazululo sokuqala sensimbi encibilikisiwe. Ukusetshenziswa okubuthakathaka kwe-silicon carbon alloy ngemva kwesixazululo sangemva kokudalwa kungenzeka kungenxa yokuhlangana komphumela we-graphitization we-post-creation kanye nokusetshenziswa kwe-silicon carbon alloy. Noma kunjalo, kulindeleke ukuthi isisombululo se-silicon-carbon alloy singenza buthaka ukuncika kwe-condensation mechanism kanye nesisombululo se-post-creation, esingase sithuthukise ukuthembeka kwezici zemishini. Ingxubevange ye-silicon-carbon ihlukile ku-ferrosilicon, i-silicon-carbon alloy inephuzu eliphezulu kakhulu lokuncibilika, bese insimbi encibilikisiwe ingancibiliki kodwa iyancibilika kancane kancane, kuyo yonke inqubo yokuncibilika ukukhombisa ama-athomu e-silicon azungezile nama-athomu omoya-mpilo. Lapho ingxubevange ye-Si-C incibilikiswa ngensimbi encibilikisiwe, izinhlayiya zegraphite ezicwengekile ezigcwele ungqimba olugcwele ziyakhiqizwa nxazonke zayo. Nakuba izinhlayiya ezinjalo ze-graphite ezihlanzekile zingancibilika, izinkampani zeqembu le-athomu ye-athomu ye-oksijini egcwele ziyakhiqizwa. Le nkampani yeqembu le-athomu ye-oxygen iyi-supercooling eyisisekelo yezingxenye ze-graphite ezihlanzekile kamuva.

I-silicon carbon alloy ingakwazi ukwandisa ikristalu, ithuthukise amandla okucindezela, ithuthukise i-ductility, ukuvimbela ukuvuza kwamanzi, ukuze izinga lemfucuza linciphe, izinga lokubuya liyancipha, ngaphezu kwe-silicon carbon alloy kulula ukuyisebenzisa, ukupakishwa kwesikhwama, kulula. isitoreji. Kulula kakhulu ukubamba inani lesicelo bese kwengezwa udoti owengeziwe wensimbi ukuze uthole izingxenye ezifanele zokuphonsa. I-silicon carbon alloy nayo ingangena esikhundleni se-ferrosilicon engu-75, inciphise ukusetshenziswa kwe-ejenti yokungcwaba futhi yehlise izindleko zokubumba.
