Icocekile okanyei-nickel e-alloy ephantsiifumana isicelo sayo esiphambili ekucutshungulweni kweekhemikhali nakwizinto ze-elektroniki.
Ukumelana nokugqwala
Ngenxa yokumelana nokugqwala kwe-nickel, ingakumbi kwiikhemikhali ezahlukeneyo zokunciphisa kwaye ngakumbi kwi-caustic alkalis, i-nickel isetyenziselwa ukugcina umgangatho wemveliso kwiimpendulo ezininzi zeekhemikhali, ngakumbi ekucutshungulweni kokutya kunye nokuveliswa kweefayibha zokwenziwa.
Iipropati zeNickel ecocekileyo yoRhwebo
Kuthelekiswa neii-alloys ze-nickelI-nickel ecocekileyo yorhwebo inombane ophezulu, iqondo lobushushu eliphezulu leCurie kunye neempawu ezilungileyo zemagnetostrictive. I-nickel isetyenziselwa iintambo ze-elekthronikhi, izinto zebhetri, ii-thyratrons kunye nee-electrodes ezivuthayo.
I-Nickel ikwanomoya ofanelekileyo wokuhambisa ubushushu. Oku kuthetha ukuba ingasetyenziselwa abatshintshi bobushushu kwiindawo ezirhabaxa.

Ukwenziwa kweNickel
I-Annealedi-nickelinobunzima obuphantsi kwaye iyakwazi ukuguguleka kakuhle. I-nickel, njengegolide, isilivere kunye nobhedu, inesantya esiphantsi sokuqina komsebenzi, oko kukuthi, ayithandi ukuba lukhuni kwaye iqhekeke xa igobile okanye ikhubazeke ngenye indlela njengezinye izinyithi. Ezi mpawu, xa zidibene nokudityaniswa kakuhle, zenza kube lula ukwenza isinyithi sibe zizinto ezigqityiweyo.
I-Nickel kwi-Chromium Plating
I-Nickel ikwasetyenziswa rhoqo njenge-undercoat kwi-chrome plating yokuhombisa. Imveliso eluhlaza, efana ne-brass okanye i-zinc casting okanye i-sheet steel pressing iqala igqunywe ngomaleko we-i-nickelubukhulu bayo bumalunga ne-20µm. Oku kuyinika ukumelana nokugqwala. Umbala wokugqibela 'yi-flash' encinci kakhulu (1-2µm) ye-chromium ukuyinika umbala kunye nokumelana nokugqwala okubonwa njengento efunekayo kwiimpahla ezifakwe ipleyiti. I-Chromium yodwa ingaba nokumelana nokugqwala okungamkelekanga ngenxa yendalo ye-chromium electroplate enemingxuma ngokubanzi.
