Kev lag luam ntshiab los yognickel tsawg alloypom nws daim ntawv thov tseem ceeb hauv kev ua tshuaj lom neeg thiab hluav taws xob.
Kev Tiv Thaiv Kev Xeb
Vim yog nickel ntshiab tsis kam rau xeb, tshwj xeeb tshaj yog rau ntau yam tshuaj txo qis thiab tshwj xeeb tshaj yog rau caustic alkalis, nickel yog siv los tswj cov khoom zoo hauv ntau yam tshuaj lom neeg, tshwj xeeb tshaj yog kev ua cov khoom noj thiab kev tsim cov fiber hluavtaws.
Cov Khoom ntawm Nickel Ntshiab Lag Luam
Piv raucov hlau nickel, nickel ntshiab uas muag hauv khw muaj kev coj hluav taws xob siab, qhov kub Curie siab thiab cov khoom siv magnetostrictive zoo. Nickel yog siv rau cov xov hlau hluav taws xob, cov khoom siv roj teeb, thyratrons thiab cov electrodes sparking.
Nickel kuj muaj kev ua tau zoo ntawm cov cua sov. Qhov no txhais tau tias nws tuaj yeem siv rau cov khoom sib pauv cua sov hauv cov chaw muaj xeb.

Kev Tsim Khoom Nickel
Annealednpib tsibmuaj qhov nyuaj tsawg thiab ductility zoo. Nickel, zoo li kub, nyiaj thiab tooj liab, muaj qhov ua haujlwm hardening qis, piv txwv li nws tsis yooj yim los ua tawv thiab brittle thaum nws khoov lossis deformed zoo li feem ntau lwm yam hlau. Cov cwj pwm no, ua ke nrog kev sib txuas zoo, ua rau cov hlau yooj yim los ua cov khoom tiav.
Nickel hauv Chromium Plating
Nickel kuj tseem siv tau ua ib txheej hauv qab hauv kev kho kom zoo nkauj chromium plating. Cov khoom nyoos, xws li tooj dag lossis zinc casting lossis cov hlau ntawv nias yog thawj zaug plated nrog ib txheej ntawmnpib tsibkwv yees li 20µm tuab. Qhov no ua rau nws tiv taus xeb. Lub tsho kawg yog ib txheej nyias nyias 'flash' (1-2µm) ntawm chromium kom muab nws xim thiab tiv taus tarnish uas feem ntau suav tias yog qhov xav tau ntau dua hauv cov khoom plated. Chromium ib leeg yuav muaj kev tiv thaiv xeb tsis zoo vim yog qhov xwm txheej feem ntau ntawm chromium electroplate.
