Dab tsi yog Qhov Zoo Ntawm Kev Siv Nickel-raws li Alloys?

Kev ua haujlwm siab, kev tiv thaiv corrosion, thiab kub tsis kam, tsim kom muaj kev lag luam txhim khu kev qha thiab ua haujlwm zoo, ua rau nws yog "cov ntaub ntawv huab tais" hauv qhov chaw huab cua.

Nickel-raws li cov alloys (xws li Inconel, Hastelloy, Monel, thiab lwm yam) yog siv dav hauv kev lag luam xws li roj, tshuaj, thiab lub zog vim lawv cov muaj pes tsawg leeg, zoo heev corrosion kuj, thiab siab - kub kuj, pab ua kom muaj kev nyab xeeb thiab ua haujlwm zoo. Lawv nthuav tawm cov kev ua tau zoo nyob rau hauv ib puag ncig huab cua xws li kub siab, corrosion, thiab kev ntxhov siab ntawm txhua yam.

 

1. Zoo heev -kub tsis kam

Siab -kub lub zog: Nickel-raws li alloys (xws li Inconel 718) tuav lub zog siab tshaj 700 degree, deb tshaj rau stainless hlau thiab titanium alloys.

Antioxidation & Anti- creep: Ib qhov ntom ntom Cr₂O₃ oxide zaj duab xis rau saum npoo, tiv thaiv kev kub siab oxidation (xws li GH 2132 siv hauv cov roj turbine).

Ntev- lub sij hawm siab - kub stability: Haum rau ntev - lub sij hawm siab - kub kev pab cuam ib puag ncig hauv aerospace cav, nuclear fais fab kub exchangers, thiab lwm yam. Daim ntawv thov:

Aerospace cav turbine hniav (Incoloy 800HT)

Petrochemical cracking rauv tubes (Incoloy 800H)

 

2. Zoo corrosion kuj

Corrosion tsis kam rau cov kua qaub & alkalis: Ua tau zoo tshwj xeeb hauv cov xov xwm corrosive xws li sulfuric acid, hydrochloric acid, thiab hydrofluoric acid (xws li Hastelloy C-276 yog resistant rau acid corrosion).

Kev tiv thaiv rau chloride ion corrosion: Yuav luag tsis muaj pitting corrosion nyob rau hauv seawater thiab ntsev tsuag ib puag ncig (xws li Monel K-500 yog siv nyob rau hauv marine engineering).

Resistance to stress corrosion cracking (SCC): Haum rau cov roj thiab roj ib puag ncig uas muaj hydrogen sulfide (H₂S) (xws li Incoloy 925). Daim ntawv thov:

Tshuaj lom neeg lub nkoj (Hastelloy B-3)

Seawater desalination khoom (Inconel 625)

 

3. Lub zog txhua yam muaj zog & zoo heev qaug zog ua haujlwm

Lub zog siab: Los ntawm kev daws teeb meem + kev laus kev kho mob (xws li 'theem Ni₃(Al, Ti)), lub zog tensile tuaj yeem ncav cuag tshaj 1000 MPa (xws li Inconel X-750).

Anti- qaug zog & tiv thaiv- vuam: Haum rau siab - lub voj voog qaug zog (xws li aerospace fasteners).

Tsawg-kub toughness: Khaws cov yas zoo ntawm -200℃(xws li cov khoom siv rau cov kua hydrogen cia tank). Daim ntawv thov:

Rocket engine Cheebtsam (Inconel 718)

Sib sib zog nqus- cov cuab yeej siv dej hiav txwv (Monel K-500)

Nexus Nova tsom mus rau qib siab -kev ua tau zoo nickel- cov khoom siv hlau, suav nrog cov raj seamless, daim hlau, cov yeeb nkab flanges, thiab cov kav dej, thiab ua haujlwm rau ntau yam xws li roj av, tshuaj lom neeg kev lag luam, lub zog, thiab marine engineering. Lub tuam txhab tau cog lus los muab cov khoom lag luam txhim khu kev qha rau cov neeg siv khoom thoob ntiaj teb los ntawm cov txheej txheem tsim khoom thiab ua tiav cov txheej txheem tshuaj xyuas zoo.
