Pehea e pale aku ai i ka poino magnet?

Hoʻohālikelike ʻia me ka ferrite a me nā mea hoʻonaninani mau loa, neodymium magnet (NdFeB magnet) loaʻa ka magnetism maikaʻi loa a ʻo ia hoʻi ka mea hoʻohana maʻamau maʻamau honua. Hoʻohana nui ʻia ia i nā mea uila, nā mīkini mana, nā mea lapaʻau, nā mea pāʻani, ka pahu, nā mīkini mīkini, aerospace a me nā ʻano ʻē aʻe. Eia nō naʻe, maʻalahi loa nā neodymium magnets (NdFeB magnets) i ka corrosion. No laila pehea e pale aku ai i ka corrosion o neodymium magnet? Aia nā ʻano hana maʻamau.
1, Phosphating
ʻO ka Phosphating kahi kaʻina hana kemika a me ka hopena electrochemical e hana i kahi kiʻi hoʻololi kemika phosphate. ʻO ka Phosphating nā kumu penei:
1. Mālama i ka metala kumu mai ka ʻinoʻino i kekahi ʻano.
2. Hoʻohana ʻia ia ma ke ʻano he kumu mua ma mua o ka pena ʻana e hoʻomaikaʻi i ka hoʻopili ʻana a me ke kūpaʻa corrosion o ke kiʻiʻoniʻoni.
3. Hoʻokani ia i ka hana o ka hōʻemi friction a me ka lubrication i ke kaʻina hana o ka hana anu.
2、 Electroplating
ʻO ka electroplating ke kaʻina hana o ka hoʻopaʻa ʻana i kahi ʻāpana lahilahi o nā metala ʻē aʻe a i ʻole nā ​​​​mea hoʻohui i ka ʻili o nā metala ʻē aʻe e ka electrolysis. ʻO ke kaʻina hana electroplating ke kaʻina 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 ka pale ʻana, conductivity, reflectance, corrosion resistance a hoʻonui i ka hopena aesthetic.
3、 Electrophoresis
Ma lalo o ka hana o ke kahua uila, neʻe nā mea i hoʻopaʻa 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 hoʻopaʻa ʻia ma o nā wikiwiki like ʻole o nā mea i hoʻopaʻa ʻia i loko o ke kahua uila i kapa ʻia ʻo electrophoresis. ʻO Electrophoresis kekahi o nā ʻenehana lapaʻau anti-corrosion surface i hoʻohana nui ʻia i ka sintered Nd-Fe-B a i hoʻopaʻa ʻia i nā magnet mau loa Nd-Fe-B. ʻAʻole wale ka hoʻopili maikaʻi ʻana o ka electrophoretic coating i ka ʻili o nā porous magnets, akā loaʻa pū kekahi i nā ʻano o ka paʻakai paʻakai, ka waikawa a me ka pale ʻana i ka corrosion alkali.
