Roughened nickel ntawv ci: Qhov saum npoo ntawmntshiab nickel ntawv ciyog kho electrochemically kom tau ib tug microscopic ntxhib qauv ntawm qhov chaw ua hauj lwm, hloov nws los ntawm hydrophobic mus rau hydrophilic los txhim kho cov kev sib raug zoo ntawm cov txheej thiab nto ntawm ib feem. Kev khi zog. Lub hom phiaj ntawm roughening yog los txhim kho cov adhesion thiab adsorption zog ntawm hlau nto thiab lwm yam ntaub ntawv. Kev ua haujlwm tshwj xeeb yog raws li hauv qab no:
(1) Cov khoom xyaw: Ib sab roughened npib tsib xee ntawv ci (purity 99.96%)
(2) Thickness: 25-65μm ( kam rau ua ± 5%)
(3) Dav: 0-300 hli
Lwm cov nickel alloy foils
1. Hlau-nickel alloy ntawv ci
Electrodeposited hlau-nickel alloy ntawv ci yog cov khoom siv hlau alloy tau los ntawm cov txheej txheem electrodeposition ntawm ob lub ntsiab hlau: hlau thiab npib tsib xee thiab ib qho me me ntawm lwm cov hlau. Cov khoom siv yog nanocrystalline. Cov ntsiab lus ntawm cov hlau thiab npib tsib xee hauv cov hlau tuaj yeem ua tiav raws li qhov xav tau sib txawv. Cov ntsiab lus sib txawv tuaj yeem siv los ua kom tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv. High-temperature annealing kev kho mob kuj tuaj yeem ua tau los txhim kho cov khoom sib nqus zoo thiab cov khoom siv kho tshuab. Nws cov kev ua tau zoo parameter yog raws li nram no:
(1) Mechanical zog ntawm hlau-nickel alloy ntawv:
Tensile zog 750-800MPa Elongation 3%-6%
(2) Cov khoom sib nqus mos ntawm hlau-nickel alloy ntawv ci

2. Invar alloy ntawv ci
Invar yog hlau-raws li high-nickel alloy, feem ntau muaj 32% -36% npib tsib xee, ib qho me me ntawm S, P, C, thiab lwm yam, thiab tus so yog li 60% Fe. Txij li cov npib tsib xee yog ib qho kev nthuav dav austenite, yog li cov nickel siab txo cov theem hloov ntawm austenite rau martensite hauv qab chav sov: -100 ~ -120 degree . Yog li ntawd, tom qab annealing, Invar alloy muaj nto thaj chaw ntawm chav tsev kub thiab nyob rau hauv ib tug tej yam kub kub nyob rau hauv lub chav tsev kub. Cov qauv austenite ntawm cov tub ntxhais lattice qauv kuj yog ib qho kev daws teeb meem tsim los ntawm cov nickel yaj hauv -Fe, yog li Invar alloy muaj cov khoom nram qab no.
(1) Me me expansion coefficient
Invar alloy tseem hu ua inflatable steel, thiab nws qhov nruab nrab expansion coefficient feem ntau yog 1.5 Ntau yam.
(2) Tsawg zog thiab hardness
Cov ntsiab lus C ntawm Invar alloy yog tsawg dua 0.05%, qhov nyuaj thiab lub zog tsis siab, lub zog tensile yog li 517MPa, lub zog tawm los yog li 276MPa, thiab Vickers hardness yog li 160. Feem ntau, lub zog tuaj yeem txhim kho los ntawm qhov txias deformation. Thaum lub zog yog nce, muaj zoo plasticity.
(3) Tsawg thermal conductivity
Lub thermal conductivity ntawm Invar alloy yog {{0}}.026 ~ 0.032cal/cm·sec· degree, uas tsuas yog 1/3-1/4 ntawm thermal conductivity ntawm 45 steel.
(4) High plasticity thiab toughness
Lub elongation, qhov txo qis, thiab cuam tshuam toughness ntawm Invar alloy yog siab heev, lub elongation δ=25%-35%, thiab qhov cuam tshuam toughness aK=18-33 kg·m / cm.
