Indlela ye-doping yindlela yendabuko yokunyibilikascandium intermediate alloys. Kubandakanya ukusonga umlinganiselo othile wobunyulu obuphezuluiscandium yesinyithikwi-aluminium, emva koko ixutywe kunye ne-aluminium etyhidiweyo phantsi kokhuseleko lwe-argon, ibambe ixesha elaneleyo, ukuyivuselela ngokucokisekileyo, kwaye iphosa kwintsimbi okanye ukubumba ubhedu olubandayo ukufumanascandium intermediate alloys. Ukunyibilika kunokwenziwa kusetyenziswa igraphite ecocekileyo okanye iicrucibles ze-alumina, kunye neendlela zokufudumeza zingenziwa ngokusebenzisa iziko lokuchasa okanye iziko eliphakathi lokungeniswa ngamaza. Le ndlela inokunyibilikisa i-alloys ephakathi equlethe i-2% ukuya kwi-4%scandium.
Umgaqo wendlela ye-doping ilula, kodwa iindawo ezinyibilikayo zescandiumkunye ne-aluminiyam yahluka kakhulu (Sc yi-1541 ℃, i-A1 yi-660 ℃). I-aluminium inyibilika idinga ukugqithiswa kwiqondo lokushisa eliphezulu, okwenza kube nzima ukulungiselela iimveliso ze-alloy eziphakathi kunye nokwakheka okuzinzile kunye nokusabalalisa okufanayo, kwaye kunzima ukuphepha ukutshiswa kwe-scandium. Ukufezekisa oku, indlela yokuphucula ukuxuba kunye nokucinezela i-scandium yensimbi ephezulu yokunyibilika kunye ne-dispersant, i-aluminium powder, i-flux, njl. kwangaphambili ngexesha lenkqubo yokulungiselela, uze udibanise kwintsimbi etyhidiweyo. I-dispersant ibola kwiqondo lokushisa eliphezulu, ukutyumza ngokuzenzekelayo i-agglomerate, enokuvelisa i-alloy efanayo kunye nokunciphisa ilahleko evuthayo yentsimbi ephezulu yokunyibilika. Kodwa ngokubanzi, iindleko zokulungiselelascandium intermediate alloysusebenzisa ubunyulu obuphezuluintsimbi yescandiumnjengoko imathiriyeli ekrwada iphezulu ngokwentelekiso, nto leyo enzima kubasebenzisi bemizi-mveliso ukuyamkela.
