ʻO ka nickel plating kahi hana e uhi ai i ka metala nickel ma ka ʻili o nā metala ʻē aʻe a i ʻole nā ​​​​mea ʻole, ma o ka electrolysis a i ʻole nā ​​hana kemika. Hiki i kēia kaʻina hana ke hoʻomaikaʻi i ke kūpaʻa corrosion, aesthetics, paʻakikī a me ke kūpaʻa ʻana o ka substrate.

Hoʻokaʻawale ʻia nā kaʻina hana nickel plating i ʻelua ʻano: electroless nickel plating a me chemical nickel plating.

1. ʻO ka paʻakai nikela: Aia ka paʻakai nickel i loko o kahi electrolyte i haku ʻia me ka paʻakai nickel (i kapa ʻia ka paʻakai nui), ka paʻakai conductive, pH buffer, a me ka mea hoʻomaʻemaʻe. Hoʻohana ʻia ka nickel metala e like me ka anode, a ʻo ka cathode ka ʻāpana i uhi ʻia. Kaʻa ʻia ke au pololei, a ʻo ka cathode ʻO kahi ʻāpana nickel plating paʻa a waiho ʻia ma luna (nā ʻāpana i uhi ʻia). ʻO ka papa nickel electroplated he kūpaʻa kiʻekiʻe i ka lewa a hiki ke pale i ka corrosion mai ka lewa, alkali a me kekahi mau waikawa. ʻO nā kristal nickel electroplated he liʻiliʻi loa a loaʻa iā ia nā waiwai polishing maikaʻi loa. Hiki i ka nickel coating polished ke loaʻa i kahi aniani e like me ke aniani a hiki ke mālama i kona luster no ka manawa lōʻihi i ka lewa, no laila hoʻohana pinepine ʻia no ka hoʻonani. Eia kekahi, ʻoi aku ka kiʻekiʻe o ka paʻakikī o ka nickel plating, hiki ke hoʻomaikaʻi i ke kūpaʻa ʻana o ka ʻili o ka huahana, no laila hoʻohana ʻia e hoʻonui i ka paʻakikī o ka papa alakaʻi e pale ai i ka corrosion e ka medium. Loaʻa i ka Nickel electroplating ka laulā o nā noi. Hiki ke hoʻohana ʻia ma ke ʻano he uhi hoʻonaninani pale e pale aku i ka mea kumu mai ka corrosion a hāʻawi ʻia i nā mea hoʻonani nani ma ka ʻili o ke kila, zinc die-casting parts,alumini aluminia me ke keleawe. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he uhi waena no nā uhi ʻē aʻe. , a laila e kau i kahi ʻāpana lahilahi o ka chromium a i ʻole kahi ʻāpana gula hoʻohālike ma luna o ia mea, e ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion a ʻoi aku ka nani o ka helehelena.
2. Electroless nickel plating: ʻIke ʻia hoʻi he electroless nickel plating, hiki ke kapa ʻia ʻo autocatalytic nickel plating. E pili ana ia i ke kaʻina hana i hoʻemi ʻia ai nā ion nickel i loko o kahi hopena wai e kahi mea hoʻohaʻahaʻa ma lalo o kekahi mau kūlana a hoʻoheheʻe ʻia ma ka ʻili o kahi substrate paʻa. ʻO ka mea maʻamau, ʻo ka uhi ʻana i loaʻa e ka electroless nickel plating ʻo Ni-P alloy a me Ni-B alloy.

Eʻoluʻolu e hoʻomaopopo i ka hoʻokō ponoʻana o ke kaʻina hana nickel plating e like me ka'āpana noi, keʻano substrate, nā kūlana mea hana, a me nā mea'ē aʻe.
