Hoʻoholo pololei ka maikaʻi o ka coating magnet i ke ola lawelawe o ka huahana

Xinfeng's hoʻokolohua hōʻike i ka cubic centimeter oSintered NdFeb Magnete ʻino ʻia e ka oxidation ma hope o ka ʻike ʻia ʻana i ka ea ma 150 ℃ no 51 mau lā.ʻOi aku ka maʻalahi o ka corrodes i nā haʻina waika nāwaliwali.I mea e paʻa ai ka NdFeb Permanent Magnet, pono e loaʻa iā 20-30 mau makahiki o ka lawelawe ʻana, pono ia e hana i ka mālama ʻana i ka corrosion, i mea e pale aku ai i ka corrosion o ka corrosive medium ma ka Magnet.A kapa pinepine iaElectroplating Permane Magnet.

I kēia manawa, hoʻohana maʻamau ʻo NdFeb i hoʻopaʻa ʻia i ka metala electroplating, electroplating + chemical gold-plating, electrophoretic coating a me phosphating treatment, etc. ua hoʻokaʻawale ʻia ke ʻano corrosive, i mea e pale ai i ka pōʻino o ka mea waena i ka magnet.

1.Generally galvanized, nickel + copper + nickel, nickel + copper + electroless nickel plating ʻekolu kaʻina hana, nā koi ʻē aʻe metala plating, maʻamau i ka nickel plating a laila nā mea metala ʻē aʻe.

2. Ma kekahi mau hihia kūikawā e hoʻohana pū i ka phosphating1) Ma nā huahana NdFeb magnet ma muli o ka huli ʻana, lōʻihi loa ka manawa mālama a ʻaʻole maopopo i ke ʻano o ka mālama ʻana i ka ʻili, maʻalahi a maʻalahi ka hoʻohana ʻana i ka phosphating;(2) I ka wā e pono ai ka magnet i ka epoxy adhesive, ka pena, ke kāpili, ka pena a me nā mea epoxy organic bonding force e pono ai ka substrate e loaʻa ka hana infiltration maikaʻi.Hiki i ke kaʻina hana Phosphating ke hoʻomaikaʻi i ka hiki infiltration o ka ʻili magnetic.

Ua lilo ka 3.Electrophoretic coating i kekahi o nā ʻano hana lapaʻau anti-corrosion surface.No ka mea, ʻaʻole ia wale nō ka ikaika hoʻopaʻa maikaʻi me ka ʻili o ka porous magnet, akā loaʻa nō hoʻi ke kūpaʻa corrosion o ka paʻakai paʻakai, ka waikawa a me ka alkali, etc.Akā ke hoʻohālikelike ʻia me ka uhi ʻana, ʻaʻole maikaʻi kona kūpaʻa ʻana i ka wela a me ka haʻahaʻa.

Hiki i nā mea kūʻai ke koho i ka uhi e like me kā lākou huahana hana koi.Me ka hoʻonui ʻana i nā noi kaʻa, ʻoi aku ka nui o nā mea kūʻai aku no ka NdFeb corrosion resistance, aKiekie Electroplating mau Magnetpono.Hoʻolālā ʻia ka hoʻokolohua HAST (PCT hoʻokolohua) no ka hoʻāʻo ʻana i ke kūpaʻa ʻino ʻana o nā mākēneki mau NdFeb sintered ma nā wahi wela a me ke kiʻekiʻe.

Pehea e hoʻoholo ai nā mea kūʻai aku inā kūpono ka uhi i nā koi?ʻO ka hoʻokolohua paʻakai paʻakai ke kumu o ka ʻili o ka pale anti-corrosion i mālama ʻia i ka sintered NdFeb magnet e hana i kahi hoʻokolohua anti-corrosion wikiwiki, i ka pau ʻana o ka hoʻokolohua, ka hāpana mai ka pahu hoʻāʻo, maloʻo, me nā maka a i ʻole ke aniani hoʻonui. e nānā i ka ʻili o ka hāpana me nā kiko, nā kiko o ka nui o ka pahu e hoʻololi ke kala.

I ka hōʻuluʻulu ʻana, ma ka hoʻomaopopo ʻana i ke kaʻina hana a me nā koi o ka huahana hiki i ka mea kūʻai ke hoʻoholo pololei i ka conformity o ka huahana.I ka pōkole, ʻo ia ka paʻa o ka hana, ka mana o ka hoʻomanawanui dimensional, ka ʻike ʻana i ka uhi a me ka loiloi o ka helehelena.

Ma ke ano o ka hana, Br(koe magnetism), Hcb(coercivity), Hcj(intrinsic coercivity), (BH) Max (maximum magnetic energy product) and demagnetization curve hiki ke ike ia e ka hana.ʻO ka hoʻomanawanui ʻana, hiki ke ana ʻia ka pololei e nā calipers vernier;Ma ka uhi ʻana, hiki ke ʻike ʻia ke kala a me ka ʻōlinolino o ka uhi ʻia e ka maka ʻōlohelohe a ʻike ʻia e ka ikaika paʻa a me ka hoʻāʻo ʻana i ka paʻakai.ʻO ka hiʻohiʻona holoʻokoʻa, me ka maka ʻōlohelohe a i ʻole ke aniani hoʻonui, a i ʻole microscope optical (no ka laina huahana ma lalo o 0.2mm), ʻoluʻolu ka ʻili o ka magnet, ʻaʻohe mea ʻike ʻia a me nā kino ʻē, ʻaʻohe kiko, ʻaʻohe kihi hāʻule hāʻule, kūpono ka helehelena.
