Zirconium raug xaiv rau nws cov kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig aqueous. Nws muaj cov coefficient tsawg ntawm thermal expansion thiab yog kub-resistant thiab hnav-resistant.
Cov Nickel Alloys puas tuaj yeem Welded?
Nickel alloys, vim lawv zoo heev corrosion kuj thiab high-temperature zog, yog dav siv nyob rau hauv kev lag luam tseem ceeb daim ntaub ntawv. Txawm li cas los xij, qhov vuam ntawm cov alloys no ua rau muaj teeb meem ntau yam vim lawv cov tshuaj lom neeg muaj pes tsawg leeg thiab lub cev muaj zog. Vuam npib tsib xee alloys yuav tsum tau ua tib zoo xav txog cov txheej txheem tsis zoo thiab xaiv cov ntaub ntawv muab tub lim tsim nyog los txo cov kev pheej hmoo ntawm kev puas tsuaj xws li kub tawg, ua kom tsis muaj zog, thiab ua kom tawv nqaij ntau dhau ntawm thaj chaw kub ntxhov (HAZ). Ib qho ntawm cov kev txhawj xeeb tseem ceeb thaum welding nickel alloys yog qhov nyiam rau cov hlau vuam kom nkag siab rau cov tawg kub. Qhov no yog vim cov nickel alloys muaj kev sib raug zoo rau leej faj, uas tuaj yeem ua rau tsim cov nickel sulfide inclusions thaum lub sij hawm solidification. Txhawm rau txo qhov kev pheej hmoo no, preheating tej zaum yuav tsim nyog los txo qhov diffusible hydrogen theem thiab ua kom qis qis qis ntawm lub pas dej welding. Tom qab-weld kev kho cua sov kuj yog feem ntau yuav tsum tau los txo cov kev ntxhov siab seem thiab rov faib cov precipitates, uas yuav pab txo qis hardness thiab susceptibility rau cracking. Xaiv txoj kev vuam zoo yog qhov tseem ceeb rau kev vam meej ntawm cov nickel alloys. Cov txheej txheem welding feem ntau suav nrog cov roj tungsten arc vuam (GTAW), roj hlau arc vuam (GMAW), hluav taws xob nqaj hlau vuam (EBW), thiab tsis kam vuam vuam. GTAW feem ntau nyiam rau nws cov precision thiab muaj peev xwm los tsim cov welds huv nrog tsawg spatter. GMAW, nrog nws cov nqi tso nyiaj ntau dua, kuj yog ib qho kev xaiv siv tau tab sis yuav tsum tau ceev faj tswj xyuas cov roj cua thiab cov cua sov. EBW muaj kev sib sib zog nqus tob thiab zoo haum rau vuam cov ntu nyias lossis koom nrog cov hlau tsis sib xws.Filler hlau xaiv yog lwm qhov tseem ceeb ntawm vuam nickel alloys. Filler hlau yuav tsum tau sib xws nrog lub hauv paus hlau thiab muab qhov tsim nyog corrosion kuj thiab txhua yam khoom. Nickel-based muab tub lim hlau feem ntau yog siv, thiab lawv tuaj yeem sib phim lossis tsis sib haum rau lub hauv paus alloy, nyob ntawm qhov kev pabcuam thiab cov khoom xav tau. Cov hlau muab tub lim yuav tsum tau ua kom huv si ua ntej siv los tiv thaiv kev nkag ntawm hydrogen, uas tuaj yeem ua rau txias kaw lossis lwm yam tsis xws luag. Consumables xws li fluxes los yog inert gases xws li argon los yog helium yuav siv tau los tiv thaiv lub weld los ntawm atmospheric paug thiab kom stabilize lub arc. Qee zaum, fluxes kuj tuaj yeem pab tsim cov slag, uas tuaj yeem pab tiv thaiv kev sib kis ntawm cov hlau.
Nickel Alloys puas tuaj yeem kho cua sov?
Nickel alloys muaj npe nrov rau lawv cov khoom siv kho tshuab zoo heev thiab tsis kam tiv thaiv corrosion ntawm qhov kub thiab txias, feem ntau vim yog cov txheej txheem kho cua sov uas ua kom zoo dua lawv cov microstructures thiab optimize lawv cov kev ua tau zoo. Kev kho cua sov muaj cov txheej txheem xws li annealing, kev daws teeb meem, kev laus, nag lossis daus hardening, thiab tempering, txhua tus haum rau cov yam ntxwv tshwj xeeb thiab cov kev xav tau ntawm cov nickel alloy hauv nqe lus nug. Annealing yog ib qho txheej txheem kev kho cua sov uas siv rau cov nickel alloys los txo cov kev ntxhov siab sab hauv, txhim kho ductility, thiab pab txhawb kev tsim lossis machining. Thaum lub sij hawm annealing, cov hlau yog rhuab mus rau qhov kub siab tshaj qhov kub ntawm recrystallization thiab ces txias ntawm tus nqi tsim nyog. Cov txheej txheem no tso cai rau cov nplej tsis muaj kab mob tshiab kom loj hlob, tshem tawm cov kev ua haujlwm nyuaj dhau los. Kev kho mob, tseem hu ua tag nrho anneal, yog siv los ua kom tiav ib theem microstructure hauv hnub nyoog-hardenable nickel alloys. Qhov kev kho no suav nrog kev nce cov hlau mus rau qhov kub siab tshaj qhov kev txwv ntawm cov khoom solubility ntawm cov khoom ntxiv thiab tom qab ntawd nrawm nrawm kom khov rau hauv cov ntsiab lus hauv cov khoom siv. Cov txheej txheem no yog npaj rau kev laus tom ntej lossis kev kho los nag. Precipitation hardening yog ib txoj kev siv los ua kom muaj zog ntawm cov nickel alloys. Tom qab kev daws teeb meem, cov hlau yog raug rau lub voj voog tswj cua sov uas txhawb cov nag lossis daus ntawm qee theem hauv matrix. Tus nqi ntawm qhov txias tom qab qhov kev kho mob no tuaj yeem cuam tshuam qhov loj thiab kev faib tawm ntawm precipitates, uas nyob rau hauv lem txiav txim siab txhua yam khoom ntawm alloy. Lub hnub nyoog hardening yog txheej txheem cuam tshuam qhov twg cov hlau yog tuav ntawm qhov kub thiab txias rau lub sijhawm tshwj xeeb los ua kom cov nag lossis daus ntawm hardening theem. Cov txheej txheem no tau ua tib zoo tswj kom ua tiav lub zog xav tau yam tsis muaj kev cuam tshuam ductility ntau dhau. Kev tswj cov kev kho cua sov, nrog rau qhov kub thiab txias, lub sijhawm, cua sov thiab cua txias, thiab qhov xwm txheej ntawm thermal cycles, yog qhov tseem ceeb rau kev ua tiav cov khoom xav tau hauv cov nickel alloys. Piv txwv li, qhov ceev ceev ntawm qhov txias txias yuav ua rau muaj kev ntxhov siab los yog qhov tsis sib xws ntawm microstructure, thaum tus nqi qeeb heev yuav tso cai rau cov theem tsis xav tau los nag ntxov ntxov. Qhov ua tau zoo ntawm kev kho cua sov ntawm cov nickel alloys nyob ntawm cov alloy muaj pes tsawg leeg thiab cov kev pabcuam tshwj xeeb uas nws yuav ntsib. Qee cov alloys yuav xav tau ntau yam kev kho cua sov los yog kev sib xyaw ua ke kom ua tiav qhov kev sib npaug ntawm lub zog, ductility, thiab corrosion kuj.
