Pehea e pale aku ai i ka pala o ka magnet?

Ke hoʻohālikelike ʻia me ka ferrite a me nā mea magnet paʻa ʻē aʻe, he magnet maikaʻi loa ka magnet neodymium (magnet NdFeB) a ʻo ia hoʻi ka magnet honua laha i hoʻohana nui ʻia. Hoʻohana nui ʻia ia i nā mea uila, nā mīkini mana, nā lako lapaʻau, nā mea pāʻani, nā ʻōpala, nā mīkini lako, aerospace a me nā ʻoihana ʻē aʻe. Eia nō naʻe, he maʻalahi loa ka neodymium magnets (NdFeB magnets) i ka pala. No laila pehea e pale aku ai i ka pala o ka neodymium magnet? Eia nā ʻano hana maʻamau:
1, Hoʻohuihui ʻana
ʻO ka Phosphating kahi hana o ka hopena kemika a me ka electrochemical e hana i kahi kiʻiʻoniʻoni hoʻololi kemika phosphate. ʻO nā kumu o ka Phosphating penei:
1. E pale i ka metala kumu mai ka pala a hiki i kekahi ʻano.
2. Hoʻohana ʻia ia ma ke ʻano he primer ma mua o ka pena ʻana e hoʻomaikaʻi i ka pipili a me ke kūpaʻa ʻana i ka pala o ke kiʻiʻoniʻoni.
3. Hoʻokani ia i ke kuleana o ka hōʻemi ʻana i ka friction a me ka lubrication i ke kaʻina hana o ka hana anu metala.
2. Hoʻopili uila
ʻO ke electroplating ke kaʻina hana o ka uhi ʻana i kahi papa lahilahi o nā metala ʻē aʻe a i ʻole nā ​​​​alloys ma luna o ka ʻili o nā metala ʻē aʻe ma o ka electrolysis. ʻO ke kaʻina hana electroplating ke kaʻina hana o ka hoʻohana ʻana i ka electrolysis e hoʻopili i ka ʻili o nā metala a i ʻole nā ​​​​mea ʻē aʻe i kahi kiʻiʻoniʻoni metala, i mea e pale ai i ka oxidation metala (e like me ka corrosion), hoʻomaikaʻi i ke kūpaʻa ʻaʻahu, conductivity, reflectance, corrosion resistance a hoʻonui i ka hopena aesthetic.
3. Electrophoresis
Ma lalo o ka hana a ke kahua uila, neʻe nā ʻāpana i hoʻopiʻi ʻia i ka electrode e kū pono ana i ko lākou uila, i kapa ʻia ʻo electrophoresis. ʻO ka ʻenehana o ka hoʻokaʻawale ʻana i nā ʻāpana i hoʻopiʻi ʻia ma o nā wikiwiki like ʻole o nā ʻāpana i hoʻopiʻi ʻia i loko o kahi kahua uila i kapa ʻia ʻo electrophoresis. ʻO Electrophoresis kekahi o nā ʻenehana lapaʻau ʻili anti-corrosion i hoʻohana nui ʻia i nā magnet paʻa Nd-Fe-B sintered a me Nd-Fe-B i hoʻopaʻa ʻia. ʻAʻole wale ka uhi electrophoretic i loaʻa ka hoʻopili maikaʻi i ka ʻili o nā magnet porous, akā loaʻa pū kekahi i nā ʻano o ka paʻakai paʻakai, ka waikawa a me ke kūpaʻa alkali.
