Bonded NdFeB Magnets
Bonded NdFeB, inoumbwa neNd2Fe14B, ndeye synthetic magineti. Bonded NdFeB magineti magineti anogadzirwa ne "press molding" kana "injection molding" nekusanganisa inokurumidza-kudzimwa NdFeB magineti poda uye binder. Bonded magineti ane high dimensional kurongeka, anogona kugadzirwa kuita magineti zvinhu zvine maumbirwo akaomarara, uye ane hunhu hwekuumbwa kweimwe-nguva uye akawanda-pole kutaridzika. Bonded NdFeB ine high mechanic simba, uye inogona kuumbwa panguva imwe chete nezvimwe zvinotsigira zvikamu.
Bonded magineti akaonekwa kutenderera kuma1970 apo SmCo yaitengeswa. Mamiriro emusika emagineti akaiswa sintered akanaka kwazvo, asi zvakaoma kunyatsoagadzirisa kuita akakosha maumbirwo, uye anowanzo pwanya, kukuvadzwa, kurasikirwa kwemupendero, kurasikirwa kwekona uye mamwe matambudziko panguva yekugadzirisa. Mukuwedzera, hazvisi nyore kuunganidza, saka kushandiswa kwavo kune zvishoma. Kugadzirisa dambudziko iri, magineti echigarire anodimburwa, akasanganiswa nepurasitiki, uye anotsikirirwa mundima yemagineti, ingangove iri nzira yechinyakare yekugadzira yemagineti akasungwa. Bonded NdFeB magineti akashandiswa zvakanyanya nekuda kwemutengo wakaderera, yakakwira dimensional kurongeka, rusununguko rwakakura rwechimiro, simba rakanaka remuchina, uye chiedza chakananga giravhiti, nekukura kwepagore kwe35%. Kubva pakabuda NdFeB yekusingaperi magineti poda, anochinjika akasungirirwa magineti akawana kukurumidza kusimudzira nekuda kwehukuru hwayo hwemagineti.
