Akhiwa kanjani izibuthe ze-neodymium?

Inqubo yokukhiqiza kamagnethi we-neodymium iyafana nesitini sokwakha esifakwe esitofini esishisayo. Ngokwelashwa kwamazinga okushisa aphezulu, kwenza isitini siqine futhi siqine.

Inqubo yokukhiqiza eyinhloko kazibuthe we-neodymium iyinqubo yokucwilisa, yingakho sikubiza ngozibuthe be-sintering neodymium. Izithako eziyinhloko i-neodymium(Nd 32%), i-Ferrum(Fe 64%) kanye ne-Boron(B 1%), yingakho sibiza futhi omazibuthe be-neodymium ukuthi babe ngozibuthe be-NdFeB. Inqubo ye-sintering ivikelwe ngegesi ye-inert (njenge-nitrogen, i-argon noma i-helium gas) esithandweni se-vacuum, njengoba izinhlayiya kazibuthe zincane njengama-microns angu-4, zivutha kalula, uma zivezwe emoyeni, kulula uku-oxidized nokubamba umlilo, sizivikela ngegesi engasebenzi ngesikhathi sokukhiqiza, futhi kuzothatha cishe amahora angu-48 esitofini esishisayo. Kuphela ngemva kokucwilisa singakwazi ukuzuza ingots kazibuthe eqinile futhi eqinile.

Yini ingots kazibuthe? Sinezinhlayiya kazibuthe ezicindezelwe ekubunjeni noma ekusetshenzisweni kwamathuluzi, uma udinga uzibuthe we-disc, khona-ke sinesikhunta se-disc, uma udinga i-block magnet, khona-ke sinesikhunta se-bock, izinhlayiya kazibuthe zicindezelwa esikhunjini sensimbi bese ziphuma. ingots uzibuthe, khona-ke sinalezi ingots uzibuthe eziphathwa esithandweni sintering ukuze kuzuzwe isimo esiqinile. Ukuminyana kwama-ingots ngaphambi kokucwiliswa kucishe kube ngu-50% wokuminyana kwangempela, kodwa ngemva kokuncibilika, ukuminyana kwangempela ngu-100%. Ukuminyana kukazibuthe we-Neodymium ngu-0.0075 gram cubic millimeters ngayinye. Ngale nqubo izilinganiso zikazibuthe ingots zincipha cishe ngo-70% -80% futhi umthamo wazo wehliswa cishe ngo-50%. Ukuguga ingots kazibuthe ngemva sintering ukulungisa izakhiwo zensimbi.

Izakhiwo eziyisisekelo kazibuthe zisethwa ngemva kokuqedwa kwezinqubo zokuguga nokuguga.
Izilinganiso zezakhiwo eziyinhloko kazibuthe ezihlanganisa ukuminyana kwe-remanence flux, ukuphoqelela, kanye nomkhiqizo wamandla omkhulu kurekhodiwe kufayela. Yilabo ozibuthe abadlula ukuhlolwa kuphela abazothunyelwa ezinqubweni ezilandelayo ukuze kuqhutshekwe nokufakwa imishini, ukucwenga, ukwenza uzibuthe nokwenza umhlangano wokugcina, njll.

Ngokujwayelekile sifinyelela izidingo zokubekezelela ikhasimende ngomshini, ukugaya kanye nama-abrasives, njengokusika kukazibuthe kuzoba njengomshini we-CNC, njll. senza ngokwezifiso imishini ekhethekile ukwenza ukucubungula okuhlukile kumazibuthe. Mningi umsebenzi okufanele wenziwe ukuze kuhlangatshezwane nezidingo ezikhethekile zamakhasimende.
