Ingemuva
Okumsulwa kwezohwebo nomai-nickel ephansi ye-alloyithola ukusetshenziswa kwayo okuyinhloko ekucutshungulweni kwamakhemikhali naku-electronics.
Ukumelana Nokugqwala
Ngenxa yokumelana nokugqwala okumsulwa kwe-nickel, ikakhulukazi kumakhemikhali anciphisa ahlukahlukene futhi ikakhulukazi kuma-alkali e-caustic, i-nickel isetshenziselwa ukugcina ikhwalithi yomkhiqizo ekuphenduleni kwamakhemikhali amaningi, ikakhulukazi ukucubungula ukudla kanye nokukhiqizwa kwefayibha yokwenziwa.
Izakhiwo Ze-Nickel Ehlanzekile Yezentengiselwano
Uma kuqhathaniswaama-alloys e-nickel, i-nickel ehlanzekile kwezohwebo ine-conductivity ephezulu kagesi, izinga lokushisa eliphezulu le-Curie kanye nezakhiwo ezinhle ze-magnetostrictive. I-Nickel isetshenziselwa izintambo zikagesi eziholayo, izingxenye zebhethri, ama-thyratron nama-electrode ashisayo.
I-Nickel nayo inokuhamba kahle kwe-thermal. Lokhu kusho ukuthi ingasetshenziselwa izishintshisi zokushisa ezindaweni ezonakalisayo.

Ukwakhiwa kwe-Nickel
I-Annealedi-nickelinobulukhuni obuphansi kanye ne-ductility enhle. I-Nickel, njengegolide, isiliva nethusi, inezinga eliphansi lokuqinisa umsebenzi, okusho ukuthi ayijwayele ukuba lukhuni futhi ibe brittle lapho igobile noma ikhubazekile njengoba kwenza ezinye izinsimbi eziningi. Lezi zimfanelo, ezihlangene nokushisela okuhle, zenza insimbi ibe lula ukwenza izinto eziqediwe.
I-Nickel ku-Chromium Plating
I-nickel ibuye isetshenziswe kaningi njengejazi elingaphansi ekuhlobiseni i-chromium plating. Umkhiqizo ongahluziwe, ofana nethusi noma i-zinc casting noma ukucindezelwa kwensimbi kuqala kuhlanganiswe ungqimba lwei-nickelcishe u-20µm ubukhulu. Lokhu kuyinikeza ukumelana nokugqwala. Ijazi lokugcina 'liyiflashi' elincanyana kakhulu (1-2µm) le-chromium ukulinika umbala kanye nokumelana nokonakala okuvame ukuthathwa njengokufiseleka kakhulu ezintweni ezipuletiwe. I-Chromium iyodwa ingaba nokumelana nokugqwala okungamukelekile ngenxa yemvelo evamise ukuba nezimbotshana ye-chromium electroplate.
