Folasaga
Super alloys po'o le maualuga o fa'atinoga o lo'o maua i le tele o foliga ma aofia ai elemene i tu'ufa'atasiga eseese e maua ai se fa'ai'uga fa'apitoa.O nei fa'ameamea e tolu ituaiga e aofia ai u'amea fa'avae, cobalt-based ma nickel-based alloys.O fa'amea sili e fa'atatau i le nickel ma le cobalt o lo'o maua e pei o fa'amea lafo po'o u'amea fa'avae e tusa ai ma le tu'ufa'atasiga ma le fa'aogaina.
Super alloys lelei oxidation ma fetolofi teteʻe ma e mafai ona faʻamalosia e ala i timuga faʻamaʻaʻaina, faʻamaʻa-fofo faʻamalosi ma galue faʻamalosi auala.E mafai foi ona latou galulue i lalo o le mamafa o masini ma le maualuga o le vevela ma i nofoaga e manaʻomia ai le mautu maualuga.
HASTELLOY(r) C276 ose u'amea fa'a'a'amea fa'a'a'amea e tete'e ai le atina'eina o fa'aputuga o saito e fa'aleagaina e fa'aleagaina ai le fa'amea.
Ole fa'amaumauga o lo'o i lalo o lo'o maua ai se fa'amatalaga lautele ole HASTELLOY(r) C276.
