Nickel Alloys for Manufacturing Aero- cav Turbine Blades - Kev Paub

1.Nickel-base Alloys Haum rau Kev Tsim Kho Aero- cav Turbine Blades

Wrought Nickel{0}}puag Superalloys

GH4169 (Inconel 718): Nws muaj cov khoom siv zoo heev ntawm qhov nruab nrab thiab qis qis, kev ua haujlwm zoo, thiab tsim nyog rau kev tsim cov turbine blades ntawm qis -siab thiab nruab nrab- ntu ntu ntawm aero- cav.

GH4145 (Inconel X-750): Nrog lub zog siab, corrosion kuj thiab zoo creep kuj qis dua 700 degree, nws yog siv los tsim cov turbine hniav rau qee qhov me thiab nruab nrab - loj aero- cav.

Cast Nickel{0}}base Superalloys

K417G: Ib tug npib tsib xee-chromium-cobalt-raws li cam khwb cia superalloy nrog zoo heev - kub lub zog thiab oxidation kuj, dav siv rau manufacturing siab - siab turbine hniav ntawm me me thiab nruab nrab thrust aero - cav.

ib 738lc: Nws muaj cov thermal qaug zog ua haujlwm zoo thiab kev ua haujlwm nkag siab ntawm 900 degree, thiab yog ib qho khoom siv rau turbine blades ntawm roj turbine xyaw thiab aero- cav.

Powder Metallurgy Nickel{0}}base Superalloys

fwv 95: Npaj los ntawm cov txheej txheem hmoov hlau metallurgy, nws muaj cov qauv microstructure, siab purity thiab zoo heev -kub txhua yam khoom, thiab yog siv rau kev tsim high- siab turbine hniav ntawm siab heev -thrust aero - cav.

Rene 88 DT: Nrog lub zog nkag siab thiab qaug zog ua haujlwm, nws tsim nyog rau turbine blades ntawm siab -kev ua tau zoo aero- cav ua haujlwm nyob rau hauv cov xwm txheej hnyav.

Lub ntsiab yog vim li cas vim li cas cov hlau no haum rau turbine hniav manufacturing yog lawv zoo heevsiab - kub lub zog, creep kuj, oxidation kuj thiab thermal qaug zog kuj, uas tuaj yeem tiv taus qhov hnyav ua haujlwm ntawm qhov kub thiab txias, kev kub siab thiab kev kub ceev airflow hauv aero- cav.

2. Common Nickel-puag Alloys hauv Marine Engineering thiab Lawv Qhov Zoo Tshaj Plaws

Marine engineering ntsib qhov kev pabcuam hnyav xws li seawater corrosion, chloride ion yaig, siab siab thiab ntub dej hydrogen sulfide corrosion. Feem ntau siv npib tsib xee- cov alloys hauv paus thiab lawv cov txiaj ntsig tseem ceeb yog raws li hauv qab no:

Nickel{0}}Base Alloy Qib	Core Zoo	Cov ntawv thov zoo hauv Marine Engineering
Ib 625	1. Zoo heev rau pitting corrosion, crevice corrosion thiab intergranular corrosion nyob rau hauv seawater; 2. Zoo siab-kub thiab qis-kub txhua yam khoom; 3. Muaj zog tiv thaiv kev ntxhov siab corrosion cracking (SCC) tshwm sim los ntawm chloride ions	Offshore roj thiab roj pipelines, subsea wellhead khoom, seawater heat exchangers
Hastelloy C276	1. Kev tiv thaiv corrosion zoo rau oxidizing thiab txo cov xov xwm, tshwj xeeb tshaj yog tiv taus corrosion los ntawm cov tshuaj chlorine - muaj cov tshuaj; 2. Tsis muaj rhiab heev, tsis txhob intergranular corrosion; 3. Zoo weldability	Marine tshuaj ua khoom siv, desalination cog Cheebtsam, offshore flue roj desulfurization tshuab
Monel 400	1. Zoo heev corrosion kuj nyob rau hauv seawater, nrog rau kev tiv thaiv corrosion los ntawm seawater yaig thiab cavitation; 2. Zoo zog thiab toughness ntawm tsawg kub; 3. Tus nqi qis piv nrog rau lwm yam siab -kev ua tau zoo nickel- puag alloys	Marine propeller shafts, seawater twj, li qub thiab fasteners
lus 825	1. Zoo tiv thaiv corrosion los ntawm sulfuric acid, phosphoric acid thiab seawater; 2. Muaj zog tiv thaiv kev ntxhov siab corrosion tawg hauv chloride- muaj ib puag ncig; 3. Zoo heev weldability thiab formability	Offshore roj rov qab cov cuab yeej, seawater txias tshuab, subsea pipelines

Tag nrho cov txiaj ntsig tseem ceeb ntawm cov npib tsib xee no -cov alloys hauv marine engineering yogsuperior corrosion tsis kam mus rau hnyav marine ib puag ncig, ruaj khov mechanical zog nyob rau hauv complex ua hauj lwm tej yam kev mob, thiab zoo processabilityhloov mus rau kev tsim khoom ntawm - cov khoom siv hauv hiav txwv loj.
