Sintering ma lafo AlNiCo Magnet

Fa'amatalaga Puupuu:

Alnico maneta tumau o se uʻamea e faia i le alumini, nickel, cobalt, uʻamea ma isi elemene elemene.O le mea muamua maneta tumau na atiina ae i le tala faasolopito, toe foʻi i tua i le 1930s.I lena taimi, o le mea sili ona malosi le maneta ma le laʻititi o le vevela ma sili ona faʻaaogaina i masini maneta tumau.Ina ua mavae le 1960s, faatasi ai ma le oo mai o ferrite maneta ma sese lalolagi maneta tumau, o le vaega o AlNiCo afi na faaalia ai se agai i lalo, o lona uiga o le faaaogaina o AlNiCo maneta tumau i afi ua suia malie.

Faailoga o oloa

Alnico mea maneta tumau e le mafai ona mamanuina o ni vaega faʻavae ona o foliga o le maualalo o le malosi faʻainisinia, maualuga le maaa, brittleness, ma le le lelei o masini.E naʻo sina laʻititi laʻititi poʻo le EDM e mafai ona faʻaaogaina i le taimi o gaioiga, o isi auala e pei o le faʻamalosi ma isi masini e le mafai ona faʻaogaina.

AlNiCo e masani ona gaosia e ala i le tuʻuina atu o auala.E le gata i lea, e mafai foi ona faʻaogaina le paʻu paʻu e fai ai maneta sintered, lea e laʻititi laʻititi le faʻatinoga.Cast AlNiCo e mafai ona fa'agasolo i lapopo'a ma foliga eseese a'o oloa AlNiCo sintered e masani ona la'ititi.Ma o mea faigaluega o le AlNiCo sintered e sili atu le faʻafeiloaʻiga, o mea faʻamaneta e laʻititi laʻititi ae o le masini e sili atu.

O le lelei o AlNiCo maneta e maualuga remanence (e oʻo atu i le 1.35T), ae o le le lava o le malosi faʻamalosi e matua maualalo (e masani lava e itiiti ifo i le 160kA / m), ma o le demagnetization curve e le laina, o lea AlNiCo o se maneta faigofie e. ia maneta ma faigofie foi ona demagnetized.Pe'a fa'ata'atia le maneta ma le gaosiga o masini, e tatau ona totogi fa'apitoa ma e tatau ona fa'amautu muamua le maneta.Ina ia aloese mai le faʻaleagaina o le faʻaleagaina poʻo le faʻalavelaveina o le tufatufaina atu o le mamafa o le mageta, e matua faʻasaina le faʻafesoʻotaʻi ma soʻo se mea ferromagnetic aʻo faʻaaogaina.

Tu'u AlNiCo maneta tumau o loʻo i ai le faʻamauina o le vevela e mafai ona faʻaaogaina i totonu o mea maneta tumau, o le vevela galue e mafai ona oʻo atu i le 525 ° C, ma le vevela Curie i le 860 ° C, o le mea maneta tumau ma le maualuga Curie point.Ona o le mautu lelei o le vevela ma le mautu o le matua, AlNiCo maneta e faʻaaogaina lelei i afi, meafaifaʻaili, masini eletise, ma masini mageta, ma isi.
