Fa'aliga Fa'alautele Fa'alalo Kovar 4j29 Uaea, 29HK Uaea mo tioata fa'amaufa'ailoga.
Alloy-4J29 e le gata o loʻo i ai le faʻalauteleina o le vevela e tutusa ma le tioata, ae o lona faʻalauteleina o le vevela e le laina laina e mafai ona masani ona faia e fetaui ma se tioata, ma faʻatagaina ai le sooga e faʻafeiloaʻi le lautele o le vevela.I le vaila'au, e pipii i tioata e ala i le vaega o le oxide intermediate ole nickel oxide ma cobalt oxide;o le vaega o le iron oxide e maualalo ona o lona faʻaititia ma le cobalt.O le malosi o le fusi e faʻalagolago tele i le mafiafia o le oxide layer ma uiga.O le iai o le cobalt e faigofie ai ona liusuavai ma solo i totonu o le tioata u'amea.O se lanu efuefu, efuefu-lanu moana po'o le lanu enaena-enaena e fa'aalia ai se fa'amaufa'ailoga lelei.O le lanu uʻamea e faʻaalia ai le leai o se oxide, ae o le lanu uliuli e faʻaalia ai ua sili atu le faʻamaʻiina, i tulaga uma e lua e oʻo atu ai i se sooga vaivai.
Talosaga:E masani ona faʻaaogaina i vaega eletise eletise ma le faʻatonutonuina o le faʻamalo, faʻalavelave faʻafuaseʻi, faʻamalo faʻamalo, tioata magnetron, transistors, faʻamaufaʻailoga faʻamau, relay, taʻavale faʻatasi, taʻavale, puipui ma isi faʻamaufaʻailoga fale.
