Nickel Molybdenum Alloy

 

Nickel Molybdenum Alloy yog cov khoom siv ua haujlwm siab - raws li cov nickel nrog molybdenum ua thawj alloying. Nyob ntawm cov ntsiab lus molybdenum thiab cov ntsiab lus ntxiv, nws yog dav siv nyob rau hauv huab cua thiab xav tau kev lag luam ib puag ncig xws li chemical engineering, zog, marine engineering, thiab aerospace, thiab yog cov khoom siv tseem ceeb rau kev daws teeb meem cuam tshuam txog kev thauj mus los thiab cov tshuaj tiv thaiv ntawm cov tshuaj corrosive heev.

 

 

1. Kev tiv thaiv corrosion los ntawm kev txo cov xov xwm

Cov yam ntxwv tseem ceeb tshaj plaws ntawm cov hlau no yog nws cov kev tiv thaiv corrosion zoo heev hauv kev txo qis ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm lawv kam rau hydrochloric acid. Raws li cov ntsiab lus molybdenum nce (feem ntau ntawm 15% thiab 30%), tus nqi corrosion ntawm cov hlau hauv hydrochloric acid txo qis. Piv txwv li, B-3 alloy ua kom pom qhov ua tau zoo rau txhua qhov concentration thiab kub ntawm hydrochloric acid. Tsis tas li ntawd, hom alloy no kuj muaj kev ua siab ntev rau nruab nrab cov kua qaub xws li sulfuric acid, phosphoric acid, formic acid, thiab acetic acid, uas tsis yog oxidizing acids.

 

2. Zoo heev tiv thaiv corrosion hauv zos

Qhov sib ntxiv ntawm molybdenum ho txhim kho cov khoom tiv thaiv rau pitting thiab crevice corrosion tshwm sim los ntawm chloride ions, ua rau lawv haum rau seawater thiab siab - ntsev ib puag ncig. Nyob rau tib lub sijhawm, cov ntsiab lus siab nickel muab cov alloy zoo heev rau cov tshuaj chloride ion kev nyuaj siab corrosion cracking, uas yog ib qho tseem ceeb hauv tshuaj thiab marine engineering.

 

3. Zoo heev -kub txhua yam khoom

Cov hlau no muaj peev xwm tuav tau lub zog txhua yam thiab kev ruaj ntseg zoo txawm tias qhov kub thiab txias (qee qib tuaj yeem ncav cuag 800 degree), thiab feem ntau yog siv rau hauv siab - kub thiab siab - cov cuab yeej siv siab. Cov qib tshwj xeeb xws li HY-MU 80 (Ni-80% Fe-15% Mo) muaj cov thermal expansion coefficient tsawg (kwv yees li 12.0 µm/m-degree), ua rau lawv haum rau cov khoom siv hluav taws xob uas xav tau kev tswj xyuas qhov loj.

 

4. Kev ua haujlwm zoo thiab vuam khoom

Cov qib niaj hnub ntawm cov hlau no (xws li B-3, C-276) tau txhim kho thermal stability los ntawm kev tswj cov ntsiab lus ntawm carbon thiab silicon. Piv nrog rau B-2 alloy ua ntej, qhov kev txhim kho tuaj yeem siv ncaj qha tom qab vuam (piv txwv li, hauv lub xeev weld), tsis tas yuav muaj kev kho cua sov ntxiv, yog li txo cov nqi ua haujlwm thiab sijhawm.

 

 

 

 

1.Chemical Engineering thiab Petrochemicals

Cov alloys no tau siv dav hauv cov cuab yeej siv los tuav hydrochloric acid, sulfuric acid thiab cov kua qaub sib xyaw, xws li cov hlab ntsha thiab cov khoom siv hluav taws xob. Hauv kev tsim cov khoom siv tshuaj lom neeg yooj yim xws li PVC, MDI / TDI, C-276 alloy yog cov khoom siv txheem. Tsis tas li ntawd, hom alloy no kuj tseem siv rau hauv cov tshuab hluav taws xob desulfurization, khib nyiab incineration cog cov pa tawm scrubbers, thiab hydrogenation desulfurization units hauv roj av refining, tiv taus kub kub los ntawm leej faj thiab chloride.

 

2. Aerospace thiab Defense

Lawv yog siv los tsim cov turbine hniav, cov tshuab tso pa, thiab cov khoom sib xyaw ua ke ntawm cov roj turbine xyaw. Lawv qhov siab - kub thiab siab - lub zog muaj zog tuaj yeem tiv taus qhov kub ntxhov siab thaum lub cav pib thiab lub davhlau. High- qib zog xws li MP35N yog siv vim lawv cov kev tiv thaiv zoo heev rau hydrogen embrittlement, hauv NASA qhov chaw cov cuab yeej torsion springs, missile tis deployment mechanisms, thiab nuclear valve springs.

 

3. Marine Engineering thiab Zog

Hauv kev tshem tawm cov roj thiab roj tawm hauv ntug dej, cov ntaub ntawv no tau siv rau hauv qhov sib sib zog nqus- cov khoom siv hauv hiav txwv drilling, cov cuab yeej hauv qab, thiab cov khoom siv lub taub hau kom tiv thaiv dej hiav txwv corrosion thiab sulfide kev nyuaj siab corrosion tawg los ntawm hydrogen sulfide. Hauv kev lag luam nuclear, cov alloys no tau siv rau hauv cov tshuab hluav taws xob nuclear thiab siv cov khoom siv roj reprocessing los tiv thaiv qhov hnyav corrosive ib puag ncig uas tshwm sim los ntawm nuclear fission.

 

4. Lub zog ntsuab tshiab

Nrog rau kev hloov pauv lub zog, cov hlau no ua lub luag haujlwm tseem ceeb hauv kev tsim cov hydrogen ntsuab, siv los ua cov electrodes thiab cov khoom tseem ceeb hauv cov dej electrolysis. Lawv cov kev ua haujlwm siab catalytic thiab ua haujlwm rau alkaline ib puag ncig corrosion ua rau lawv cov khoom siv zoo tshaj plaws los tsim cov hydrogen ntsuab. Tsis tas li ntawd, cov alloys no kuj tau siv rau hauv kev tsim cov khoom siv kho mob (xws li lub plawv pacemaker leads) thiab cov cuab yeej phais, siv kom zoo dua ntawm lawv cov biocompatibility, tsis yog - magnetism, thiab lub zog muaj zog.

 

5. Cov khoom siv hluav taws xob thiab sib nqus

Alloys nrog siab nickel thiab molybdenum cov ntsiab lus (xws li HY-MU 80) muaj qhov sib nqus permeability siab heev thiab siv nyob rau hauv cathode ray hlab, precision transformers, thiab sib nqus shielding npog rau magnetic probes kom tshem tawm cov kev cuam tshuam sab nraud thiab xyuas kom ruaj khov ntawm cov khoom siv.
