Iinzuzo ze-silicon carbon alloy

Ukusebenzisa i-silicon carbon alloy ukusombulula intsimbi ekrwada etyhidiweyo ye-grey cast iron inokutshintsha kakhulu iimpawu zekristale yentsimbi etyhidiweyo, ukunciphisa umkhwa womlomo wothuthu kunye nokususa umlomo ochasene nothuthu. Umkhwa wesango lothuthu ukubuyisela umva isango lothuthu lunxulumene nomthamo wokuvelisa inyukliya wegraphite yococeko oluphezulu. Kunokuvakala ukuba i-silicon carbon alloy inomsebenzi wokudala kwisisombululo sokuqala sentsimbi etyhidiweyo. Ukusetyenziswa okubuthathaka kwe-silicon carbon alloy emva kwesisombululo se-post-creation mhlawumbi ngenxa yengozi yempembelelo ye-graphitization ye-post-creation kunye nokusetyenziswa kwe-silicon carbon alloy. Nangona kunjalo, kulindeleke ukuba isisombululo se-silicon-carbon alloy singenza buthathaka ukuxhomekeka kwendlela yokudibanisa kunye nesisombululo se-post-creation, esinokuphucula ukuthembeka kweempawu zendlela. I-silicon-carbon alloy yahlukile kwi-ferrosilicon, i-silicon-carbon alloy inendawo ephezulu kakhulu yokunyibilika, kwaye emva koko intsimbi enyibilikisiweyo ayinyibiliki kodwa ngokuthe ngcembe iyanyibilika, kuyo yonke inkqubo yokunyibilika ukubonisa iiathom zesilicon ezijikelezileyo kunye neeathom zeoksijini. Xa i-alloy ye-Si-C inyibilikiswa kwintsimbi etyhidiweyo, i-full-layer ecolekileyo ephezulu-yobunyulu ye-graphite particles yenziwa ngeenxa zonke kuyo. Nangona amasuntswana egraphite acoceke kakhulu anokuphinda anyibilike, iinkampani zeqela le-athomu ye-oxygen egcweleyo ziyenziwa. Le nkampani yeqela leathom yeoksijini yeyona nto iphambili yokupholisa izinto ezicocekileyo zegraphite kamva.

I-silicon carbon alloy inokwandisa ikristale, iphucule amandla oxinzelelo, iphucule i-ductility, ukuthintela ukuvuza kwamanzi, ukuze izinga lenkunkuma lincitshiswe, izinga lokubuyiswa liyancitshiswa, ngaphezu kwe-silicon carbon alloy kulula ukuyisebenzisa, ukupakishwa kwengxowa, kulula. yokugcina. Kulula kakhulu ukubamba ubungakanani besicelo kwaye ke inkunkuma eyongezelelekileyo ingongezwa ukufumana iindawo ezifanelekileyo zokuphosa. I-silicon carbon alloy inokuthi ithathe indawo ye-75 ferrosilicon, ukunciphisa ukusetyenziswa kwe-carburizing agent kunye nokunciphisa iindleko zokubumba.
