Dab tsi yog qhov sib txawv ntawm Monel 400 thiab K500?
1. Dab tsi yog qhov tseem ceeb tshaj plaws cuam tshuam rau corrosion tsis kam ntawm monel alloys?
Monel aleloys, suav nrog 400 thiab K500, yog muaj npe rau lawv cov marine corrosion tsis kam, tab sis muaj ntau yam kev coj ua qhov kev ua tau zoo no. Ua ntej, lub tsib xee - tooj liab piv yog qhov tseem ceeb: thaum tooj liab txhim kho kev ua haujlwm zoo li dej hiav txwv. Qhov thib ob, qhov kub hloov pauv tuaj yeem cuam tshuam corrosion cov nqi {5} {txaus} kev tawm tsam huab cua, txawm tias Monel qhov kev tsis kam yog superior rau ntau cov hlau. Thib peb, kis los rau cov sulfides los yog chlorides hauv hiav txwv corrosion lossis monel lub teb chaws mitigates mitigates zoo dua li tooj dag lossis cov hlau. Ib qho ntxiv, kev ntxhov siab kho tshuab, yog tias ua ke nrog cov neeg sawv cev corrosive, SCC), tab sis Monel lub hauv paus siab ua rau nws nyiam ua kom ntev li cov khoom siv ntawm cov kiv cua lossis cov raj hauv qab.
2. Yuav ua li cas ua daus hardening hauv Monel K500 cuam tshuam nws lub tshuab luam ntawv piv rau Monel 400?
Zoov nag zog hardening haj yam m4el k500 lub tshuab ua hauj lwm zoo li cov txheej txheem zoo li txoj kev hnav khaub ncaws zoo li tig, drilling, lossis milling nrog kev txiav ceev. Hauv kev sib piv, Monel K500, kev loj hlob, txhim kho lub microstructure vim yog nplua ni₃ (al, ti) precipitates, uas nce lub zog tensile thiab hardness. Lub xeev tawv hardened ua rau K500 ntau cov abrasive rau tej cuab yeej, ua rau cov khoom siv siab dua thiab cov khoom siv harder (piv txwv li, carbide ntxig). Ib qho ntxiv, cov kev txo qis duction ua rau kev pheej hmoo ntawm chip breaking teeb meem thaum lub tshuab pub mis, feem ntau xav tau kev siv cov nqi lossis kev siv tshuab kom tiv thaiv kev kub ntxhov. Rau cov ntawv thov uas xav tau kev siv machining dav dav, K500 qee zaum machined -}}}}}} kev kho ua ntej kev kho mob sov, ntsuas nrog qhov xav tau lub zog siab.
3. Hauv kev siv cov khoom siv muaj Monel 400 yuav tsum muaj dua Monel K500?
Nyob rau hauv marine engineering, 400 yog qhov zoo rau tsis yog- Cov qauv pauv hluav taws xob zoo li kev ua kom muaj zog yog qhov tseem ceeb tab sis muaj zog tensile tsis tsim nyog. Nws tseem pom muaj hluav taws xob engineering rau cov txuas lossis cov pob hluav taws xob, levelanced rau ntawm cov atmospheric corrosion.mon, los ntawm kev sib piv hauv siab, yog nyiam nyob rau hauv high- kev muaj kev ntxhov siab ib puag ncig. Nyob rau hauv cov roj thiab roj kev lag luam, nws yog siv rau cov cuab yeej hauv qis xws li nqus cov pas nrig thiab cov cuab yeej ntxeem tau, uas yuav tsum tau txais cov khoom siv hnyav thiab corrosion hauv cov qhov dej tob. Hauv cov ntawv thov marine, K500 yog xaiv rau cov tshuaj ntxuav tes rau cov roj hmab thiab valve stems, qhov twg nws lub zog siab tiv thaiv kev tawm tsam hnyav. Nws tseem siv nyob rau hauv ib qho kev sib xyaw ua ke zoo li cov fasteners lossis springs, qhov twg cov neeg kho mob tiv thaiv thiab lub zog yog qhov tseem ceeb rau kev cia siab.
4. Dab tsi yog qhov kev txiav txim siab tseem ceeb thaum Vuam Monel 400 piv rau Monel K500?
Rau Monel K500, Vuam Vuam yog ntau dua ua rau nws cov ntsiab lus txhuas thiab titanium cov ntsiab lus, uas tuaj yeem tsim cov theem cuam tshuam hauv bazes hauv lub taub hau yog tias overheated. Kev tawm tshiab kub thaum lub sij hawm vuam yuav yaj cov zog siv zog, txo cov posts- Cov txheej txheem cua sov zoo li gtaw yog nyiam. Ib qho ntxiv, cov chaw ua haujlwm yuav tsum zam dhau txhuas lossis titanium kom tiv thaiv kev tawg, feem ntau siv monel 400 fillers (piv txwv li} 7) hloov cov k500 tshwj xeeb. Tom qab kev kho cua sov-weld Cov tshuaj tiv thaiv kom raug (Argon nrog 2-5% hydrogen) kuj tseem muaj kev tiv thaiv oxidation los tiv thaiv oxidation ntawm txhuas thiab titanium, uas tuaj yeem txwv Weld kev ncaj ncees.
