Silicon-calcium alloy o se uʻamea tuʻufaʻatasia e aofia ai elemene silikoni, calcium ma uʻamea. O se deoxidizer tu'ufa'atasi lelei ma desulfurizer. E faʻaaogaina lautele i le gaosiga o le uʻamea maualuga, uʻamea maualalo-carbon, uʻamea uʻamea ma isi mea faʻapitoa faʻapitoa e pei o nickel-based alloys ma titanium-based alloys; e talafeagai foi e fai ma sui mafanafana mo faleaoga u'amea liliu; e mafai foi ona faʻaaogaina e avea o se inoculant mo uʻamea lafo ma faʻaopoopoga i le gaosiga o le uʻamea ductile.
fa'aoga
O le calcium ma le silicon e iai se sootaga malosi mo le okesene. O le calcium, aemaise lava, e le gata o loʻo i ai se vavalalata malosi ma le okesene, ae o loʻo i ai foi le malosi malosi ma le sulfur ma le nitrogen. O le mea lea, o le silicon-calcium alloy o se mea fa'apipi'i tu'ufa'atasi lelei ma so'o fa'a-desulfurization. Silicon alloy e le gata o loʻo i ai le malosi o le deoxidation, ma o oloa faʻamaʻi e faigofie ona faʻafefe ma lafoaʻi, ae mafai foi ona faʻaleleia le faʻatinoga o le sila, ma faʻaleleia le palasitika, aʻafiaga faigata ma le suavai o le sila. I le taimi nei, e mafai e le silicon-calcium alloy ona sui le alumini mo le deoxidation mulimuli. Fa'atatau ile sila maualuga. Gaosiga o u'amea fa'apitoa ma u'amea fa'apitoa. Mo se faʻataʻitaʻiga, togi uʻamea e pei ole uʻamea uʻamea, uʻamea maualalo carbon, ma uʻamea uʻamea, ma uʻamea faʻapitoa e pei ole nickel-based alloys ma titanium-based alloys, silicon-calcium alloys e mafai ona faʻaaogaina e pei o deoxidizers. E fetaui lelei fo'i le u'amea o le calcium-silicon e fai ma sui fa'amafanafana mo falea'oga u'amea o tagata liliu. E mafai fo'i ona fa'aogaina le u'amea o le calcium-silicon e fai ma tui mo le u'amea lafo ma se fa'aopoopo i le gaosiga o le u'amea nodular.
