Kuyika kwa nickel ndi njira yophimba zitsulo za nickel pamwamba pa zitsulo zina kapena zopanda zitsulo, makamaka kudzera mu electrolysis kapena njira zamagetsi. Njirayi imatha kusintha kukana kwa dzimbiri, kukongola, kuuma komanso kukana kwa gawo lapansi.

Njira zokutira za nickel zimagawidwa m'mitundu iwiri: plating ya nickel yopanda electroless ndi mankhwala nickel plating.

1. Nickel plating: Nickel plating ndi mu electrolyte wopangidwa ndi nickel mchere (wotchedwa mchere waukulu), conductive mchere, pH buffer, ndi chonyowetsa. Nickel yachitsulo imagwiritsidwa ntchito ngati anode, ndipo cathode ndi gawo lopukutidwa. Pakali pano amadutsa, ndipo cathode ndi A yunifolomu ndi wandiweyani nickel plating wosanjikiza waikidwa pa (zokutidwa mbali). Chosanjikiza cha nickel cha electroplated chimakhala chokhazikika mumlengalenga ndipo chimatha kukana dzimbiri kuchokera mumlengalenga, alkali ndi ma acid ena. Makristalo a nickel opangidwa ndi electroplated ndi ochepa kwambiri ndipo ali ndi zinthu zabwino zopukutira. Chophimba cha nickel chopukutidwa chimatha kukhala ndi mawonekedwe owoneka ngati galasi ndipo chimatha kukhalabe chowala kwa nthawi yayitali mumlengalenga, motero chimagwiritsidwa ntchito kukongoletsa. Kuphatikiza apo, kuuma kwa nickel plating ndikokwera kwambiri, komwe kumatha kupangitsa kuti zinthu zisamayende bwino, motero zimagwiritsidwanso ntchito kukulitsa kuuma kwa kutsogolo kuti zisawonongeke ndi sing'anga. Nickel electroplating ili ndi ntchito zambiri. Itha kugwiritsidwa ntchito ngati zokutira zodzitchinjiriza kuti ziteteze zinthu zapansi kuti zisawonongeke kapena kupereka zokongoletsera zowala pamwamba pazitsulo, zinc kufa-casting parts,zitsulo za aluminiyamundi aloyi zamkuwa. Amagwiritsidwanso ntchito nthawi zambiri ngati zokutira zapakati pazovala zina. , ndiyeno tambani chingwe chochepa cha chromium kapena golide wonyezimira pa icho, chomwe chidzakhala ndi kukana kwa dzimbiri bwino komanso kukongola kwambiri.
2. Electroless nickel plating: Imadziwikanso kuti electroless nickel plating, imathanso kutchedwa autocatalytic nickel plating. Zimatanthawuza njira yomwe ma oni a nickel mu njira yamadzimadzi amachepetsedwa ndi wothandizira pansi pazifukwa zina ndikukwera pamwamba pa gawo lapansi lolimba. Nthawi zambiri, zokutira za alloy zomwe zimapezedwa ndi nickel plating ndi Ni-P alloy ndi Ni-B alloy.

Chonde dziwani kuti kukhazikitsidwa kwachindunji kwa nickel plating process kumatha kusiyanasiyana malinga ndi malo ogwiritsira ntchito, mtundu wa gawo lapansi, zikhalidwe za zida, ndi zina zambiri. Muzochita zenizeni, ndondomeko yoyenera ya ndondomeko ndi njira zogwiritsira ntchito chitetezo ziyenera kutsatiridwa kuti zitsimikizire mtundu wa nickel plating ndi chitetezo chopanga.
