Puas yog nickel alloy xeb?
Nickel yog cov hlau nrov siv hauv kev tsim khoom. Nws paub txog nws lub peev xwm tiv taus qhov kub thiab txias, tiv thaiv corrosion thiab nws lub zog. Nickel feem ntau alloyed nrog lwm cov hlau los txhim kho nws cov khoom. Ib qho ntawm cov lus nug feem ntau nug los ntawm cov neeg tab tom nrhiav yuav cov khoom siv nickel alloy yog seb lawv xeb lossis tsis yog. Hauv tsab xov xwm no, peb yuav saib cov khoom ntawm nickel alloy thiab seb nws puas xeb.
Nickel yog dab tsi?
Nickel yog ib qho khoom siv hlau uas muaj tus lej atomic 28. Nws muaj cov xim dawb-dawb, hardness ntawm 4 ntawm Mohs nplai, thiab melting point ntawm 1453 degrees Celsius. Nickel yog cov hlau nplaum, hlau nplaum uas tiv taus corrosion. Nws yog tsuas yog siv nyob rau hauv alloys, roj teeb, coatings, thiab catalytic converters.
Nickel suav hais tias yog ib qho kev hloov pauv hlau vim nws nyob hauv nruab nrab ntawm lub rooj zaum ntawm cov hlau thiab cov hlau tsis yog hlau. Nws tseem paub txog nws lub peev xwm tshwj xeeb rau alloy nrog lwm cov hlau. Nickel alloys yog siv nyob rau hauv ntau yam kev siv vim lawv lub zog siab, tsis kam mus corrosion, thiab kub-resistant.
Nickel Alloy yog dab tsi?
Nickel alloysyog cov alloys uas muaj nickel ua cov hlau tseem ceeb. Lawv feem ntau yog tsim los ntawm lwm yam hlau xws li hlau, tooj liab, chromium, titanium, thiab txhuas. Cov nyiaj npib tsib xee hauv cov hlau tuaj yeem yog li ntawm 5% txog 75%.
Cov khoom ntawm nickel alloy nyob ntawm nws cov muaj pes tsawg leeg. Qee cov nickel alloys yog sib nqus, thaum lwm tus tsis yog. Qee cov alloys yog ductile, thaum lwm tus yog nkig. Hom nickel alloy feem ntau yog nickel-chromium alloy, uas feem ntau siv rau hauv cov ntawv thov kub.
Puas yog Nickel Alloy Rust?
Lo lus teb rau lo lus nug no yog ob qho tib si yog thiab tsis yog. Nickel nws tus kheej tsis xeb vim nws yog cov hlau ruaj khov heev. Txawm li cas los xij, nickel alloys tuaj yeem xeb yog tias lawv muaj lwm cov hlau uas ua rau xeb, xws li hlau.
Thaum hlau raug oxygen thiab dej, nws tsim hlau oxide, uas feem ntau hu ua xeb. Yog tias cov khoom siv nickel alloy muaj hlau, cov hlau tuaj yeem xeb thiab ua rau cov nickel alloy corrode.
Txawm li cas los xij, yog tias cov nickel alloy tsis muaj hlau lossis lwm yam hlau uas ua rau xeb, cov hlau yuav tsis xeb. Nickel alloys xws li npib tsib xee-tooj liab, npib tsib xee-molybdenum alloy, thiab npib tsib xee-chromium alloy yog cov resistant rau corrosion thiab tsis xeb.
Cov yam ntxwv uas cuam tshuam rau Corrosion Resistance ntawm Nickel Alloy
Ntau yam tuaj yeem cuam tshuam rau corrosion kuj ntawm nickel alloy. Cov yam tseem ceeb no suav nrog ib puag ncig, qhov kub thiab txias, thiab hom alloy.
Ib puag ncig: Ib puag ncig uas siv cov nickel alloy tuaj yeem cuam tshuam nws cov corrosion kuj. Kev cuam tshuam rau qee yam tshuaj, ntsev, lossis av noo tuaj yeem ua rau cov hlau tsis xeb.
Kub: Qhov kub ntawm ib puag ncig uas siv cov nickel alloy tuaj yeem cuam tshuam rau nws cov corrosion kuj. Cov kub kub tuaj yeem ua rau cov hlau oxidize thiab corrode.
Hom alloy: Hom nickel alloy siv kuj tuaj yeem cuam tshuam nws cov corrosion kuj. Qee cov nickel alloys tiv taus corrosion ntau dua li lwm tus.
Yuav tiv thaiv xeb ntawm Nickel Alloy li cas
Tiv thaiv xeb ntawmnickel alloy yeeb nkablos yog phaj koom nrog kev siv qee yam kev ntsuas los tiv thaiv cov hlau los ntawm kev raug dej, oxygen, lossis lwm qhov chaw corrosive. Nov yog qee cov lus qhia los tiv thaiv xeb ntawm nickel alloys:
1. Txheej: Siv cov txheej txheem ntawm lwm cov hlau, xws li chromium lossis zinc, rau cov nickel alloy tuaj yeem tsim ib qho kev thaiv uas tiv thaiv kom tsis txhob raug dej thiab oxygen.
2. Passivation: Passivation cuam tshuam nrog kev kho qhov chaw ntawm cov nickel alloy nrog cov kua qaub uas tsim cov oxide txheej ntawm nws qhov chaw. Cov txheej txheem oxide no tiv thaiv cov hlau los ntawm kev xeb ntxiv.
3. Corrosion Inhibitors: Corrosion inhibitors tuaj yeem muab ntxiv rau ib puag ncig uas siv cov nickel alloy. Cov inhibitors tiv thaiv oxidation ntawm cov hlau los ntawm kev tsim cov txheej tiv thaiv nyob ib puag ncig nws.
4. Kev Tu: Ntxuav cov nickel alloy tsis tu ncua tuaj yeem tiv thaiv kev tsim cov khoom corrosive ntawm nws qhov chaw.
5. Kev Cia Khoom Zoo: Kev khaws cov khoom siv nickel alloy kom zoo nyob rau hauv qhov chaw qhuav tuaj yeem tiv thaiv kom tsis txhob muaj dej noo thiab oxygen.
Xaus
Nickel alloyyog ib hom hlau uas nrov siv nyob rau hauv ntau yam lag luam vim nws tsis kam mus corrosion, high-temperature kuj, thiab lub zog. Seb puas los yog tsis npib tsib xee alloy rusts nyob ntawm nws muaj pes tsawg leeg thiab ib puag ncig uas nws siv.
Nickel nws tus kheej tsis xeb, tab sis npib tsib xee alloys uas muaj hlau lossis lwm yam hlau uas ua rau xeb tuaj yeem corrode. Tiv thaiv xeb ntawm nickel alloy yuav tsum tau siv qee yam kev ntsuas xws li txheej txheej, passivation, corrosion inhibitors, tu, thiab cia kom zoo. Los ntawm kev ua raws li cov kev ntsuas no, koj tuaj yeem ua kom lub neej ntev ntawm koj cov khoom siv nickel alloy.
