Superalloy yog dav dav raws li nws yog xim hlau cov khoom uas tsim kho kom khawsTshwj tsis muaj zog tshuab zog, creep tsis kam, thiab ib puag ncig ruaj khov (corrosion / oxidation tiv taus)Nyob rau hauv huab kev ua hauj lwm cov kev mob - feem ntau kub (piv txwv li cov hlau, aluminium alloys) muag muag, deform, lossis corrode sai. Superalloys muaj kev sib txuas ntxiv los ntawm lawv lub hauv paus hlau (tsib xee}}}}}
Monel ua tau raws li cov lus txhais no overarching, txawm tias nws qhov kev ua tau ua ntej lav rau corrosion tsis kam tshaj li ultra- kub lub zog uas txhais tau ib qho ntxiv lwm tus superalloys.
Monel aleloys - feem ntau {% Nickel, thiab 1-2% duab, 1-27%) {[30%
Qhov no yog Monel lub ntsiab lus txhais thiab lub cim ntawm superalalloy kev ua haujlwm. Tsis zoo li cov hlau, monel hais txog kev tsis pom zoo hauv qee qhov chaw hnyav:
Dej Dej & Cov Neeg Hiav Txwv Marine: Nws tiv thaiv pitting, thiab biofatic corrosion, thiab biofacle - Zoo dua rau cov neeg xa khoom, offshore roj platform Cheebtsam, thiab dej txias dej txias.
Acidic / Alkaline Media: Nws tawm tsam los ntawm sulfuric acid, hydrochloric acid (dilute {}} qhov tseem ceeb rau cov khoom siv tshuaj lom neeg xws li cov raj thiab cov raj.
High - xidation kub: Ntawm qhov kub txog 700℃(1292 Qib F), nws tsim oxide oxide txheej (oxide oxide) uas txwv tsis pub ua rau oxide ntxiv, outperforming stainless hlau nyob rau hauv xws li ntau.
Qhov kev ib puag ncig no ruaj khov ncaj qha ua ke nrog "ib puag ncig ruaj khov" yuav tsum muaj rau superalloys.
Thaum Monel tsis tsim rau cov ultra - qhov siab kub (1000} Cov Sij Hawm Kub (1832-2192 Dag Zog
Nyob rau ntawm chav tsev kub, monel 400 muaj lub zog tensile ntawm ~ 275 mpa- sib piv rau ntau cov hlau.
Thaum 600℃(1112 Qib F), nws khaws tau ~ 70% ntawm nws chav {}} kub tensile, tooj kib}, lossis txawm tias qee qhov qis}}}}}}}}}} cov hlau ineloy.
Rau Monel K - 500 (ib qho nag lossis daus {
Qhov peev xwm no "ua nyob rau hauv tshav kub" yog qhov tseem ceeb superalalloy tus cwj pwm.
Superalloys yuav tsum tau thev tsis tau tsuas yog zoo li qub cua sov lossis corrosion, tab sis pheej rov qab muaj kev ntxhov siab mus (thermal lossis mechanical) yam tsis muaj kev ua tsis tiav. Monel excred ntawm no:
Thermal rog tsis kam: Nws tiv thaiv cov cua sov / cua txias dua (piv txwv li ntawm 2500℃thiab rov qab rau cov li qub lossis cua sov hloov pauv.
Hnav Tsis kam: Nws lub siab tawv (Monel 400: ~ 11el K-500: ~ 43
Thaum Monel yog superalloy, nws nyob ib qho txawv ntawm niche piv rau high- kub superalalloys zoo li Inconel 718 lossis Waspaloy. Lub ntsiab lus sib txawv nyob hauv cov qauv tsim ua ntej:
Qhov kev sib txawv no tsis cais tawm Monel los ntawm Superalaly kev faib tawm {}}} {1} {{}} umented superalloy).
Monel alloys unequivocally tsim nyog li nickel - bued supallots. Lawv tau raws txhua tus tub ntxhais kawm supalloy: Qhov tshwj xeeb ib puag ncig ib puag ncig (kev kho mob corrosion Thaum lawv tus qauv tsim ua ntu ntu ua ntej tshaj li ultra- qhov kev ua haujlwm siab, qhov tshwj xeeb {4 4}
