Ngaba Imagnethi Eyomeleleyo inokugqithiswa? Ithetha ukuthini iPasivation?

I-Passivation yinkqubo esetyenziselwa ukukhusela izinto ekudlekeni. Kwimeko kaumazibuthe owomeleleyo, inkqubo ye-passivation idlala indima ebalulekileyo ekugcineni amandla kunye nokusebenza kwemagnethi ekuhambeni kwexesha.

Imagnethi eyomeleleyo, eyenziwe ngezinto ezinjeneodymiumokanyecobalt samarium, iyakwazi ukubola xa ibonakaliswe kumswakama okanye iimeko ezithile zokusingqongileyo. Oku kunokukhokelela ekunciphiseni amandla umazibuthe kunye nokusebenza ngokubanzi. Ukuthintela oku, i-passivation isoloko isetyenziselwa ukudala umqobo okhuselayo kumphezulu wemagnethi.

I-Passivation ibandakanya ukusetyenziswa kwezinto ezinqabileyo, ezifana ne-oxide yensimbi okanye i-polymer, efakwe kumphezulu wemagnethi. Lo maleko usebenza njengesithintelo, ukhusela umazibuthe kwi-corrosion kunye nezinye iindlela zokuwohloka. Inceda ukugcina amandla kunye nokusebenza umazibuthe, nokuba sele evezwe kwindawo ezinomngeni.

Enye yeenzuzo eziphambili ze-passivation kukukwazi ukwandisa ubomi bemagnethi eyomeleleyo. Ngaphandle kwe-passivation, umazibuthe unokuqalisa ukuwohloka ngokuhamba kwexesha, nto leyo ekhokelela ekuncipheni kwamandla ayo omlingo kunye nokusebenza kwawo. Ngokusebenzisa i-passivation layer, umazibuthe unokugcina amandla kunye nokusebenza ixesha elide, ekugqibeleni unikezela ngexabiso elikhulu kunye nokuthembeka.

Ngoko, ngaba umazibuthe owomeleleyo unokukhutshwa? Impendulo nguewe. Ngapha koko, i-passivation linyathelo elibalulekileyo kwinkqubo yokwenziwa kweemagnethi ezininzi ezinamandla. Ngaphandle kwe-passivation, ezi magnethi zinokuthambekela ngakumbi ekudlekeni kwaye azinakukwazi ukugcina amandla kunye nokusebenza kwazo ekuhambeni kwexesha.

Kubalulekile ukuqaphela ukuba i-passivation ayiyona inkqubo yexesha elinye. Ngokuhamba kwexesha, umaleko we-passivation unokuqalisa ukuguga okanye uthobeke, ngakumbi ukuba umazibuthe ubhengezwe kwindawo ezirhabaxa. Ngenxa yoko, ukugcinwa rhoqo kunye nokugqithiswa kwakhona kunokuba yimfuneko ukuze kuqinisekiswe ukuba umazibuthe uyaqhubeka nokwenza ngcono.

Ukuqukumbela, i-passivation yinkqubo ebalulekileyo yokugcina amandla kunye nokusebenza kwemagnethi eyomeleleyo. Inceda ukukhusela umazibuthe ekudlekeni kunye nezinye iindlela zokuwohloka, ekugqibeleni yandisa ubomi bayo kunye nokugcina ukuthembeka kwayo. Nabani na osebenza ngemagnethi eyomeleleyo, ukuqonda inkqubo ye-passivation kunye nokubaluleka kwayo kubalulekile ekuqinisekiseni ukusebenza okuqhubekayo kwezi zixhobo zixabisekileyo.
