Imvelaphi
Urhwebo olunyulu okanyenickel ye-alloy ephantsiifumana usetyenziso lwayo oluphambili ekusetyenzweni kweekhemikhali kunye ne-elektroniki.
Ukunyangwa kokuMhlwa
Ngenxa yokunganyangeki kokutya kwe-nickel, ngakumbi kwiikhemikhali ezahlukeneyo zokunciphisa kwaye ngakumbi kwi-alkalis ye-caustic, i-nickel isetyenziselwa ukugcina umgangatho wemveliso kwiimpendulo ezininzi zeekhemikhali, ngakumbi ukulungiswa kokutya kunye nokuveliswa kwefayibha yokwenziwa.
Iipropathi zeNikeli ecocekileyo yoRhwebo
Kuthelekiswa neialloys nickel, i-nickel esulungekileyo yorhwebo ine-conductivity ephezulu yombane, ubushushu obuphezulu beCurie kunye neempawu ezintle zemagnetostrictive. I-Nickel isetyenziselwa iingcingo ezikhokelayo ze-elektroniki, izinto zebhetri, ii-thyratron kunye nee-electrode ezihlwahlwazayo.
I-Nickel nayo ine-conductivity efanelekileyo ye-thermal. Oku kuthetha ukuba ingasetyenziselwa ukutshintshiselana kobushushu kwindawo ezonakalisayo.

Ukwenziwa kweNickel
I-Anealednickelinobulukhuni obuphantsi kunye ne-ductility elungileyo. I-Nickel, njengegolide, isilivere kunye nobhedu, inomlinganiselo ophantsi wokuqiniswa komsebenzi, okt ayithandeki ukuba lukhuni kwaye ibe brittle xa igobile okanye ikhubazeke njengezinye iintsimbi ezininzi. Ezi mpawu, zidibaniswe ne-weldability efanelekileyo, yenza isinyithi silula ukwenza izinto ezigqityiweyo.
I-Nickel kwi-Chromium Plating
I-nickel isetyenziswa rhoqo njenge-undercoat kwi-chromium yokuhombisa. Imveliso ekrwada, enje ngobhedu okanye i-zinc casting okanye i-sheet steel pressing iqatywe ngomaleko.nickelmalunga ne-20µm ubukhulu. Oku kuyinika ukuxhathisa kwayo kumhlwa. Idyasi yokugqibela 'yiflash' ebhityileyo kakhulu (1-2µm) yechromium ukuyinika umbala kunye nokunganyangeki okugqalwa njengokunqweneleka kakhulu kwimpahla epleyitiweyo. I-Chromium iyodwa inokuba noxhathiso olungamkelekiyo ekumdleni ngenxa yobume oburhabaxa be-chromium electroplate.
