Vim li cas nickel raws superalloys?
Tag nrho cov qib sib txawv ntawm INCONEL muaj cov nickel siab, nrog cov flagship INCONEL alloy 625 uas muaj tsawg kawg yog 58% npib tsib xee hauv nws cov muaj pes tsawg leeg. Thaum ua ke nrog ntau cov chromium, cov nickel alloys muaj kev tiv thaiv corrosion zoo dua thiab kub tsis kam tshaj lwm cov alloys sib tw.
Nickel high kub alloy ua
Txawm li cas los xij, thaum xaiv los siv ib qho ntawm cov nickel-based superalloys, nws yog ib qho tseem ceeb kom nkag siab tias yuav ua li cas rau lawv. Cov khoom siv tshwj xeeb thiab cov khoom siv no yuav tsum tau ua thiab ua tiav los ntawm cov kws ua haujlwm uas nkag siab txog cov khoom tshwj xeeb ntawm INCONEL ntau yam. Yog tsis muaj txoj hauv kev thiab cov txheej txheem, cov khoom siv nickel tuaj yeem ua haujlwm nyuaj.
Ua ntej, koj yuav tsum tsom mus rau kev ua haujlwm ceev. Siv cov khoom carbide kawg mills los tshuab cov hlau ruaj khov ntawm kev kub ceev tuaj yeem ua rau lub neej luv thiab ua rau kev ua haujlwm nyuaj. Qhov no txhais tau tias koj yuav tsum tau npaj kom rov kho koj cov riam lossis hloov koj cov cuab yeej tsis tu ncua. Txawm li cas los xij, koj tuaj yeem siv cov cuab yeej ua haujlwm siab ceev ntawm qhov qeeb qeeb yog tias qhov no yog qhov kev xaiv zoo tshaj plaws rau koj lub tshuab.
Koj tuaj yeem xaiv siv cobalt laum me ntsis, tshwj xeeb tshaj yog thaum siv twist xyaum me ntsis. Yog tias ua tau, nws tseem tsim nyog siv qib C cov hniav, uas yog kim dua tab sis ua kom cov hlau no yooj yim dua. Tag nrho cov kev xaiv cuab yeej no tuaj yeem cuam tshuam rau koj cov khoom tsim khoom, yog li sim xaiv qhov sib xyaw ua ke rau koj txoj kev lag luam.
Lwm qhov yuav tsum tau xav txog thaum machining cov ntsiab lus siab nickel alloys yog siv cov coolant. Machining cov nickel superalloys ua kom muaj cua sov ntau, uas tuaj yeem ua rau cov khoom deform thaum lub sij hawm machining. Tej zaum koj yuav xav tau kev sim nrog kev sib xyaw kom raug thiab tus nqi ntawm cov coolant thiab lubricant nyob ntawm qhov project. Rau CNC machining, piv txwv li, qee tus engineers tau pom tias siv cov dej-soluble zaub roj-raws li kua tuaj yeem txhim kho kev tsim khoom.
Vuam thiab filling ntawm nickel superalloys
Nws kuj tseem ua tau rau vuam nickel superalloys, tab sis zoo li machining, nws yuav tsum muaj qee qhov kev xyaum, kev paub, thiab kev paub. Txij li cov high-nickel alloys no tau tsim los tiv taus qhov kub thiab txias, qhov no tuaj yeem ua rau vuam cov khoom nyuaj thiab cov vuam yuav tawg.
Xaiv cov khoom filling zoo yog qhov tseem ceeb. Cov khoom siv zoo li INCONEL Alloy 625 yog qhov kev xaiv zoo rau kev muab tub lim los koom nrog ob daim ntawm superalloy ua ke. Yog tias cov welds tau ua tiav nrog qhov tseeb thiab kev txawj, ces cov welds yuav tsum muaj zog thiab tiv taus corrosion.
Thaum nws los txog rau txoj kev vuam, feem ntau pom zoo yog roj tungsten arc vuam (GTAW, tseem hu ua tungsten inert gas welding lossis TIG). Rau qhov zoo tshaj plaws, qhov no yog qhov zoo dua rau lwm cov txheej txheem vuam xws li roj av arc vuam (GMAW) lossis nplaum arc vuam (SMAW).
