Magnet Akasimba Inogona Kupfuura Here? Chii chinonzi Passivation chinorevei?

Passivation inzira inoshandiswa kuchengetedza chinhu kubva mukuora. Kana ari amagineti yakasimba, iyo passivation process inoita basa rakakosha kuchengetedza simba nemagineti nekufamba kwenguva.

Magineti akasimba, akagadzirwa nezvinhu zvakaita seneodymiumkanasamarium cobalt, inobatwa negora kana yaiswa muhunyoro kana mamwe mamiriro ekunze. Izvi zvinogona kutungamira mukudzikira kwesimba remagineti uye kuita kwese. Kudzivirira izvi, passivation inowanzoshandiswa kugadzira chidziviriro chekudzivirira pamusoro pemagineti.

Passivation inosanganisira kushandiswa kwechinhu chakatetepa chezvinhu, sesimbi oxide kana polymer, iyo inoshandiswa pamusoro pemagineti. Iyi dhizaini inoshanda sechivharo, inodzivirira magineti kubva mukuora uye mamwe maitiro ekuora. Inobatsira kuchengetedza simba remagineti uye kuita kwayo, kunyangwe kana yaiswa munzvimbo dzakaoma.

Imwe yemabhenefiti makuru epassivation kugona kwayo kuwedzera hupenyu hwemagineti yakasimba. Pasina passivation, magineti inogona kutanga kuderera nekufamba kwenguva, zvichikonzera kudzikira kwesimba rayo remagineti uye kuita. Nekushandisa passivation layer, iyo magineti inogona kuchengetedza simba rayo uye kuita kwayo kwenguva yakareba, pakupedzisira ichipa kukosha kukuru uye kuvimbika.

Saka, magineti akasimba anogona kubviswa here? Mhinduro ndihongu. Muchokwadi, passivation inhanho yakakosha mukugadzira maitiro emagineti mazhinji akasimba. Pasina passivation, magineti aya angave akanyanya kuita ngura uye aisazokwanisa kuchengetedza simba ravo nekuita nekufamba kwenguva.

Zvakakosha kuziva kuti passivation haisi yenguva imwe chete. Nekufamba kwenguva, iyo passivation layer inogona kutanga kupera kana kudzikisira, kunyanya kana magineti akaiswa munzvimbo dzakaoma. Nekuda kweizvozvo, kugara uchigadzirisa uye kupfuudza zvakare kungave kuri madikanwa kuti ive nechokwadi chekuti magineti inoramba ichiita pakugona kwayo.

Mukupedzisa, passivation inzira yakakosha yekuchengetedza simba uye kuita kwemagineti yakasimba. Inobatsira kuchengetedza magineti kubva mukuora uye mamwe maitiro ekuora, pakupedzisira ichiwedzera hupenyu hwayo uye kuchengetedza kuvimbika kwayo. Kune chero munhu anoshanda nemagineti akasimba, kunzwisisa maitiro ekufambisa uye kukosha kwayo kwakakosha kuti uve nechokwadi chekuenderera mberi kwekuita kwezvinhu izvi zvakakosha.
