Kwakasimba sei kukweva kweNdFeB magineti akasimba?

Sei kwakasimba here kusveta kweNdFeB magineti akasimba?

NdFeB magineti parizvino ndiwo ane simba risingaperi magineti. NdFeB magineti ari pari zvino magineti anonyanya kutengeswa. Vanozivikanwa samambo yemagnetism. Ivo vane yakanyanya kukwirisa magineti zvivakwa uye hukuru hwavo magineti simba chigadzirwa (BHmax) inodarika ka10 yakakwira kupfuura iyo ye ferrite. Ndiyo zvakare inonyanya kushandiswa isingawanzo pasi magineti parizvino, uye iyo inoshandiswa muzvikamu zvakawanda uye zviridzwa zvakaita semagineti edu akajairika mota, dhisiki madhiraivha, uye magineti resonance imaging.

Yayo pachayo machinability zvakare yakanaka chaizvo. Kushanda tembiricha inogona kusvika ku200 madhigirii Celsius. Uyezve, maitiro ayo akaoma, kushanda kwayo kwakagadzikana, uye ine mutengo wakanaka kuita, saka kushandiswa kwayo kwakakura zvakanyanya. Asi nekuda kwekuita kwayo kwakasimba kwemakemikari, inofanirwa kurapwa nepamusoro coating. (Zvakadai seZn, Ni plating, electrophoresis, passivation, nezvimwewo).

The main chikamu cheNdFeB magineti haawanzo pasi chinhu neodymium. Rare pasi harisi inonzi rare earth nekuda kwekushomeka kwayo, asi yakanyanya kuoma zvakasiyana pane zvimwe zvinhu zvakabatanidzwa nemakemikari bonds. Kunyangwe iyo magineti kukwezva kweNdFeB magineti yakasimba kwazvo, inotova nerunyerekupe kuti NdFeB magineti anogona kutora 600 nguva uremu hwavo. Asi chaizvoizvo, izvi chirevo hachina kukwana, nekuti iyo magineti kukwezva iri zvakare kukanganiswa nemamiriro akawanda akadai sechimiro uye chinhambwe. Somuenzaniso, nokuda magineti ane dhayamita imwechete, iyo yakakwirira magineti, inosimba kwazvo magnetic attraction simba; kune magineti ane urefu hwakafanana, iyo yakakura iyo dhayamita, ndiko kukura kwesimba remagineti rekukwezva.
