ʻO nā koi ʻenehana o NdFeb magnet i ke kaʻina hana

ʻO ka ʻenehana pale kemika oNdfeb Neodymium MagnetʻO ka mea nui e pili ana i ka electroplating a me ka hoʻoheheʻe electroless o nā uhi metala, ke kiʻi hoʻololi o nā uhi seramika a me ka pulupulu a me ka electrophoresis o nā uhi kūlohelohe.I ka hana ʻana, hoʻohana maʻamau ia e hoʻomākaukau i ka uhi pale metala ma ka ʻili o nā magnet NdFeb ma ke kaʻina hana electroplating.ʻO ka electroplating kahi hana e hoʻohana ʻia ai ka mea hana magnetic e like me ka cathode a me ka cation metala i loko o ka hopena electroplating e hoʻemi ʻia ma ka ʻili o ka magnet ma o ka hoʻohana ʻana i ke au o waho e hana i kahi uhi metala.ʻO ka pale electroplating oNā Mākēneki Neodymium SinteredʻO ka mea nui e hoʻomaikaʻi i ke kūpaʻa corrosion o nā magnet, a me ka hoʻomaikaʻi ʻana i nā waiwai mechanical surface a me ka hoʻonani.

Ma hope o nā makahiki o ka hana ʻana a me ka hoʻohana ʻana, ʻike maopopo ʻia nā hemahema o ka NdFeb magnet electroplating coating: Nui ka porosity o ka uhi, ʻaʻole paʻa ka uhi, a he ʻano hoʻomanawanui.E mānoanoa ke kihi o ka mea hana ma muli o ka manaʻo o ka laina mana i ke kaʻina electroplating, no laila ke kihi o kaMākēneki mau loa ka Honuapono e hoʻopaʻa ʻia, a ʻaʻole hiki ke uhi ʻia ka hāpana lua hohonu.He hopena pōʻino ke kaʻina hana electroplating i ka matrix magnet.I kekahi mau manawa koʻikoʻi, ma hope o ka hoʻohana ʻia ʻana o ka electroplating coating no ka manawa lōʻihi, e ʻike ʻia ka uhi ʻana i ka haki ʻana, peeling, maʻalahi e hāʻule a me nā pilikia ʻē aʻe, a e emi iho ka hana pale.Me ka hoʻomaikaʻi ʻana i ka ʻike kaiapuni, piʻi nui ka hapa o ke kumukūʻai o ka electroplating ʻekolu o ka mālama ʻana i ka ʻōpala. 

Neodymium ElectromagnetʻO ka ʻenehana hoʻoheheʻe nickel e pili ana i ka hopena REDOX o ka paʻakai metala a me ka mea hoʻohaʻahaʻa i loko o ka ʻauʻau me ka ʻole o ka hoʻohui ʻana i kahi au i hoʻohana ʻia.Ma lalo o ka catalytic hana o ka workpiece ili, ke kaʻina hana o ka metala ion ho'ēmi deposition.Hoʻohālikelike ʻia me ka electroplating, he mea maʻalahi nā lako kaʻina hana electroless plating, ʻaʻole pono i ka mana a me ka electrode kōkua, ʻokoʻa ka mānoanoa o ka uhi ʻana, ʻoi aku ka kūpono no ke ʻano o ka mea hana paʻakikī, nā ʻāpana lua hohonu, ka paipu i loko o ka paia o ka pā, ka paʻakikī a me ka paʻakikī o ka uhi. ʻoi aku ke kiʻekiʻe.Loaʻa i ka electroless plating kekahi mau hemahema, ʻaʻole piʻi ka mānoanoa o ka uhi, hiki ke hoʻopaʻa ʻia i nā ʻano like ʻole, ʻoi aku ka kiʻekiʻe o ke kaʻina hana, ʻoi aku ka paʻakikī o ka mālama ʻauʻau.ʻO ka hoʻoheheʻe ʻana kemika ka nui o ka nickel plating, keleawe plating a me ke kala kala.

Eia hou, ke kaʻina hana oNā Mākēneki Neodymium Sinteredua prone i micro lua, kaawale hale, oolea ili a me ka 'ē aʻe hemahema, a me NdFeb mau magnet i loko o ka noi o ka hana kaiapuni pinepine kiʻekiʻe wela, kiʻekiʻe humidity.Hāʻawi kēia mau hemahema i nā kūlana kūpono no ka NdFeb magnet corrosion i ke kiʻekiʻe wela a me ka haʻahaʻa haʻahaʻa.I ka manawa like, ua maʻalahi ka hana ʻana o NdFeB i ka O, H, Cl a me nā mea haumia ʻē aʻe a me kā lākou hui, ʻo ka hopena corrosive ʻo O a me Cl mau mea, magnets a me O oxidation corrosion, a ʻo Cl a me kāna mau pūhui e hoʻolalelale i ka oxidation. kaʻina hana o ka magnet.ʻO nā kumu o ka maʻalahi o ka hoʻoheheʻe ʻana o nā magnet NdFeb e pili ana i: ka ʻenehana hana, ka ʻenehana a me ka ʻenehana hana.Hōʻike ka noiʻi i ka ʻino ʻana o ka NdFeB magnet i loko o kēia mau ʻano ʻekolu: ka mahana a me ka haʻahaʻa, ka honua electrochemical, lōʻihi ka lōʻihi o ka mahana wela ma kahi maloʻo, ke haʻahaʻa ka mahana ma mua o 150 ℃, ʻoi aku ka nui o ka oxidation rate o NdFeb magnet. lohi.
