'apamemea
O le fa'aogaina o le 'apamemea ma le 'apamemea na amata mai i seneturi ua mavae, ma o aso nei o lo'o fa'aaogaina i nisi o tekonolosi fou ma fa'aoga a'o fa'aogaina pea o lo'o fa'aaogaina masani e pei o mea fai musika, mata apamemea, mea teuteu ma tap ma meafaigaluega faitotoa.
O a Mea e Faia i Ai?
O le apamemea o se mea faʻapipiʻi e faia mai le tuʻufaʻatasiga o le kopa ma le zinc e gaosia ai mea faʻatasi ma le tele o faʻaoga faʻainisinia.O le tu'ufa'atasiga o le apamemea e maua ai le u'amea se mea fa'afefeteina e talafeagai mo le tele o fa'aoga, e aofia ai le talafeagai mo le tu'ufa'atasia i le fa'aogaina o le fa'aogaina o le fa'aogaina.O le mea liusuavai o le apamemea e maualalo ifo nai lo apamemea i le 920 ~ 970 tikeri Celsius e faʻatatau i le aofaʻi o le Zn faaopoopo.O le mea e liusuavai ai apamemea e maualalo ifo nai lo le apamemea ona o le Zn faaopoopo.O u'amea apamemea e mafai ona fesuia'i ile fa'aupuga o le Zn mai le la'ititi e pei ole 5% (sili ona ta'ua ole Gilding Metals) i luga ole 40% e pei ona fa'aaogaina i apamemea masini.O se faaupuga e le masani ona fa'aaogaina o le 'apamemea apamemea, lea e fa'aogaina ai nisi fa'aopoopoga o apa.
O le a le mea e fa'aoga ai le apamemea?
O le tuufaatasiga o le apamemea ma le faaopoopoga o le zinc i le kopa e siitia ai le malosi ma maua ai le tele o uiga, lea e avea ai apamemea o se vaega sili ona lelei o meafaitino.O lo'o fa'aaogaina mo lo latou malosi, fa'a'ele'ele, foliga ma lanu, ma faigofie ona galue ma fa'atasi.O le vaega e tasi alpha brasses, e o'o atu i le 37% Zn, e matua ductile ma faigofie i galuega malulu, uelo ma braze.Ole vaega lua ole alpha-beta apamemea e masani ona vevela.
E sili atu ma le tasi le fatu apamemea?
E tele 'apamemea e eseese tu'ufa'atasiga ma uiga fa'atatau mo fa'aoga fa'apitoa e ala ile maualuga ole fa'aopoopoga ole zinc.Ole vaega pito i lalo ole fa'aopoopo Zn e masani ona ta'ua o Guilding Metal po'o Red Brass.A'o maualuga maualuga ole Zn o mea fa'ameamea e pei ole Cartridge Brass, Free Machining Brass, Naval Brass.O nei apamemea mulimuli ane o loʻo iai foʻi le faʻaopoopoga o isi elemene.O le fa'aopoopoina o le ta'ita'i i le 'apamemea ua fa'aaogaina mo le tele o tausaga e fesoasoani ai i le fa'aogaina o mea e ala i le fa'aosoina o mea e malepe ai.A'o iloa le lamatiaga ma le mata'utia o le ta'ita'i, e le'i leva atu ona suia i elemene e pei o le silikoni ma le bismuth e ausia ai uiga fa'apena tutusa.O nei mea ua iloa nei o le ta'ita'i maualalo po'o apamemea leai se ta'ita'i.
E mafai ona faaopoopo isi elemene?
Ioe, e mafai fo'i ona fa'aopoopoina i le 'apamemea ma le 'apamemea ni vaega laiti o isi elemene fa'afefiloi.O faʻataʻitaʻiga masani e taʻitaʻia mo masini-mafai e pei ona taʻua i luga, ae faʻapea foʻi le arsenic mo le faʻafefeteina i le dezincification, apa mo le malosi ma le pala.
Lanu 'apamemea
A'o fa'atuputeleina le zinc, e suia le lanu.O u'amea maualalo Zn e masani ona pei o le 'apamemea i le lanu, a'o le maualuga o le zinc e foliga mai e auro pe samasama.
