Tšebeliso ea silicon carbon alloy ha ho etsoa tšepe
Li-alloys tsa silicon-carbon li bapala likarolo tse ngata tsa bohlokoa ho etseng tšepe.Pele ho tsohle, silicon-carbon alloy, e le deoxidizer e kopantsoeng, e sebelisoa haholo-holo bakeng sa ho ntša deoxidation ha ho qhibiliha tšepe e tloaelehileng ea carbon.Mokhoa ona oa deoxidation o ka khutsufatsa nako ea oksijene haholo, kahoo oa boloka matla, oa ntlafatsa ts'ebetso ea tšepe, oa fokotsa tšebeliso ea thepa e tala, oa fokotsa tšilafalo ea tikoloho le ho ntlafatsa maemo a ts'ebetso.Ntle le moo, alloy ea silicon-carbon e boetse e na le phello ea carburizing, e leng ea bohlokoa haholo ho ntlafatsa melemo e felletseng ea libopi tsa motlakase.
