Qhov nyob nram qab
Kev lag luam ntshiab lossisTsawg alloy npib tsib xeePom nws cov ntawv thov tseem ceeb hauv kev ua lag luam tshuaj thiab khoom siv hluav taws xob.
Corrosion Kuj
Vim tias ntawm cov ntshiab nickel lub corrosion tsis kam, tshwj xeeb yog siv los tswj cov khoom lag luam zoo, tshwj xeeb yog kev ua cov khoom noj thiab cov khoom siv hluavtaws tau ua haujlwm.
Cov yam ntxwv ntawm cov neeg lag luam nickel
Piv rauNickel alloys, Cov lag luam Nickel muaj hluav taws xob muaj hluav taws xob muaj hluav taws xob, kub siab thiab txias thiab zoo magertawm cov khoom ntiag tug. Nickel siv rau cov xov hluav taws xob coj ua, cov roj teeb, thyratrons thiab sparking electrodes.
Nickel tseem muaj qhov zoo thermal conductivity. Qhov no txhais tau tias nws tuaj yeem siv rau cov kev sib pauv cua sov hauv cov chaw muaj teeb meem.

Fabrication ntawm Nickel
Ib qho tseem ceebtus menyuam yausmuaj lub hardness tsawg thiab ua qauv zoo. Nickel, zoo li kub, nyiaj thiab tooj liab, muaj cov ua haujlwm tsis muaj zog, piv txwv li tsis yog khoov lossis tsis muaj kev cuam tshuam nrog lwm cov hlau. Cov cwj pwm no, ua ke nrog weldability zoo, ua kom cov hlau yooj yim rau cov ntaub qhwv rau hauv cov khoom tiav.
Npib tsib xee nyob chromium plating
Nickel tseem siv tau ua ib qho undercoat hauv kev zoo nkauj chromium plating. Cov khoom lag luam nyoos, xws li tooj dag lossis zinc casting lossis ib daim ntawv steel nias yog thawj zaug nrog ib txheejtus menyuam yausKwv yees li 20μm tuab. Qhov no muab nws nws corrosion tsis kam. Lub tsho kawg kawg yog qhov yooj yim heev 'flash' (1-2μm) ntawm chromium muab nws ua xim thiab tarnish tsis kam uas feem ntau xav tau ntau dua nyob rau hauv wated ware. Chromium ib leeg yuav muaj tsis tau colrosion tsis kam vim tias feem ntau cov nplaim hluav taws xob electroplate.
