Puas yog Inconel nyuaj dua titanium?
Inconel
Inconel yog lub npe lag luam ntawm cov nickel-chromium high-temperature alloys uas tsim los ntawm Cov Hlau Tshwj Xeeb. Nws tiv taus qhov kub thiab txias heev thiab tuaj yeem tiv taus kwv yees li 2, 000 degree F (nyob ntawm alloy) yam tsis muaj zog. Nws kuj ua tau zoo ntawm qhov kub thiab txias.
Ntxiv nrog rau qhov kub thiab txias, Inconel muaj cov cuab yeej zoo heev ntawm chav tsev kub. Piv txwv li, Inconel 725 muaj lub zog tensile txog li 180 ksi, uas yog ob zaug lub zog ntawm cov qauv hlau. Qee cov Inconel alloys, xws li Inconel 718, yog nag lossis daus hardened, uas ntxiv zog ntxiv. Inconel kuj tseem tiv taus corrosion, nrog rau oxidation, pitting, crevice corrosion thiab corrosion cracking.
Cov khoom ntawm Inconel ua rau nws muaj txiaj ntsig zoo rau cov hlau siv rau hauv qhov xav tau tshaj plaws. Txawm li cas los xij, zoo li feem ntau superalloys, nws kim dua li cov hlau xws li hlau, txhuas thiab titanium.
Machining Inconel
Lub zog ntawm Inconel ua rau nws muaj txiaj ntsig zoo rau kev siv hauv cov xwm txheej hnyav, tab sis nws kuj ua rau nws nyuaj rau tshuab. Nws yog ib qho nyuaj heev thiab nquag ua hauj lwm hardening thaum lub sij hawm machining, uas tuaj yeem ua rau cov cuab yeej txiav thiab deform lub workpiece.
Kev ntxhov siab-relieving Inconel los ntawm kev kho ua ntej-machining daws pab txo qhov tawv tawv thiab txwv kev ua haujlwm tawv, yog li txo cov cuab yeej kev ntxhov siab thiab hnav. Ceramic txiav cov cuab yeej raug pom zoo vim tias lawv muaj peev xwm ua kom nrawm nrawm, tsis tu ncua txiav uas txo qis kev ua haujlwm hardening. Nws tseem yog ib qho tseem ceeb kom tsis txhob pecking, uas ua rau kom ua hauj lwm hardening.
Vuam Inconel
Feem ntau Inconel alloys nyuaj rau vuam vim tias cov welds tawg yooj yim. Txawm li cas los xij, qee qhov Inconel alloys yog tsim los ua welding. Cov no feem ntau yog TIG (tungsten inert gas) welded thiab siv Inconel 625 (qhov yooj yim tshaj rau vuam Inconel alloy) ua cov hlau muab tub lim. Thaum TIG vuam feem ntau tsis xav tau muab tub lim, nws raug pom zoo rau Inconel vuam vim nws nyuaj heev rau fuse ob qhov tsis muaj tawg.
Inconel daim ntawv thov
Vim nws cov tshuaj lom neeg thiab kub tsis kam, Inconel zoo haum rau ntau yam aerospace, roj thiab roj, thiab kev siv dej hiav txwv. Qee qhov xwm txheej siv rau Inconel suav nrog:
Dav hlau cav tso tawm.
Turbine.
Exhaust yeeb nkab connector.
Pawg ntawm flares.
Natural Gas Pipeline.
Marine propeller hniav.
Aerospace thiab marine fasteners.
Heavy machinery qhov chaw.
Inconel yog cov khoom siv zoo tshaj plaws thaum qhov kub thiab txias thiab corrosion kuj yuav tsum tau, tshwj xeeb tshaj yog thaum kub kub yuav txo tau lub zog thiab oxidation tsis kam ntawm lwm yam hlau.
titanium
Titanium yog ib qho khoom siv hlau uas muaj qhov sib npaug ntawm qhov hnyav-rau-qhov hnyav, ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov xws li cov khoom siv hauv aerospace qhov twg qhov hnyav yog qhov tseem ceeb. Titanium muaj zog npaum li cov hlau tab sis tsuas yog ib nrab ntawm qhov hnyav. Txawm li cas los xij, cov khoom no tuaj nrog tus nqi siab dua li ntau cov hlau xws li txhuas thiab hlau, tab sis nws feem ntau pheej yig dua Inconel.
Titanium tsis hnov mob nrog oxygen thiab dej ntawm ambient kub. Zoo li Inconel, titanium tsim ib txheej oxide passivating ntawm nws qhov chaw los tiv thaiv cov khoom. Qhov no ua rau titanium tsis tshua muaj corrosion-resistant, txawm resistant rau muaj zog acids xws li sulfuric thiab hydrochloric acid. Tsis tas li ntawd, titanium yog biocompatible thiab tsis muaj tshuaj lom, tso cai rau nws siv rau ntau yam kev kho mob.
Titanium muaj nyob rau hauv ob qib: coj mus muag ntshiab titanium thiab alloy titanium. Cov alloy feem ntau yog Ti 6Al-4V, uas yog alloyed nrog txhuas thiab vanadium thiab suav txog li ib nrab ntawm tag nrho cov titanium siv thoob ntiaj teb. Qhov no thiab lwm yam titanium alloys yog tsim los ua nyuaj, muaj zog dua thiab / lossis yooj yim rau tshuab dua li titanium ntshiab. Kev lag luam ntshiab (CP) titanium yog softer thiab ductile dua titanium alloys, tab sis nws cov corrosion kuj yog zoo heev.
Kev ua haujlwm titanium
Cov khoom uas ua rau titanium xws li cov hlau tseem ceeb kuj ua rau nws nyuaj rau tshuab. Zoo li Inconel, titanium muaj kev cuam tshuam rau kev ua haujlwm tawv. CP titanium kuj yog nplaum heev thaum machined, tsim ntev, nruam chips uas cuam tshuam nrog cov cuab yeej txiav. Cov cuab yeej no kuj ua rau nws hnav thiab tsim kua muag. Qhov no tuaj yeem raug txo los ntawm kev siv ntau lub tshuab cua txias kom tshem tawm cov chips sai li sai tau thiab khaws cov cuab yeej grooves kom huv si.
Thaum machining titanium alloys, tsis txhob cuam tshuam kev txiav thiab ib txwm ua kom lub cuab yeej nyob rau hauv kev txav thaum sib cuag nrog lub workpiece. Kev sib cuag ntau dhau tuaj yeem ua rau cov cuab yeej sib txhuam, ua kom muaj cua sov ntau dhau, thiab ua rau kev ua haujlwm nyuaj. Machining ntawm qhov qis dua thiab cov nqi pub ntau dua tuaj yeem txo qhov tsim hluav taws xob ntau.
Thaum Inconel nyuaj heev thiab nruj, titanium hloov tau yooj yim dua, yog li lub workpiece yuav tsum muaj zog tuav thiab lub zog ua tau zoo tshaj plaws. Titanium thiab nws cov alloys yog elastic heev, uas tuaj yeem ua rau lub caij nplooj ntoos hlav thiab sib tham thaum lub sijhawm ua haujlwm thiab tuaj yeem ua rau lub ntsej muag tsis zoo.
welded titanium
Titanium thiab nws cov alloys yog yooj yim rau weld. Cov txheej txheem thiab cov cuab yeej siv rau vuam titanium zoo ib yam li cov siv rau vuam lwm cov hlau tshwj xeeb, xws li cov hlau tsis muaj steel lossis npib tsib xee-raws li alloys. Txawm li cas los xij, titanium xav tau kev saib xyuas ntau dua rau kev huv thiab kev tiv thaiv roj inert dua li lwm yam hlau. Cov pa phem tuaj yeem rhuav tshem cov titanium welds.
Daim ntawv thov Titanium
Titanium's mechanical zog, tshwj xeeb tshaj yog nws lub zog-rau-qhov hnyav piv, muaj txiaj ntsig zoo hauv kev lag luam aerospace thiab tsheb. Ti 6AL-4V suav rau yuav luag ib nrab ntawm tag nrho cov alloys siv hauv kev siv dav hlau. Nws kuj yog feem ntau siv nyob rau hauv kev lag luam kev kho mob vim nws zoo heev corrosion kuj thiab biocompatibility.
Qee qhov kev siv titanium muaj xws li:
Aircraft cav thiab ncej.
Armor plating.
Navy nkoj.
lub dav hlau.
missile.
tsaws iav.
cev.
Artificial pob qij txha.
Kho vajtse siv los kho lossis kho cov pob txha.
