Stainless hlau vs Titanium Exhaust Systems: Yuav xaiv li cas

Taw qhia

Lub tshuab tso pa yuav tsum muaj sia nyob hauv tshav kub, kev vibration, txoj kev ntsev, thiab condensate thaum xa lub suab thiab qhov hnyav uas tus tswv xav tau. Stainless hlau thiab titanium yog ob yam khoom uas ua tau raws li cov kev xav tau ntawm qib kev ua tau zoo, tab sis lawv ua li ntawd nrog kev lag luam sib txawv -offs. Kab lus no piv lawv cov cuab yeej los ntawm cov cuab yeej, nrog rau cov ntaub ntawv cov ntaub ntawv uas siv rau cov qauv qib, yog li qhov kev xaiv nyob ntawm engineering thiab pob nyiaj siv tsis yog zam.

Qhov hnyav

Titanium muaj qhov ceev ntawm 4.51 g / cm³, txog 43 feem pua ​​​​qis dua stainless hlau ntawm kwv yees li 7.9 g / cm³. Lub titanium tso tawm ua rau tib lub phab ntsa tuab txuag tau li 40-45 feem pua ​​​​ntawm cov kab ke, feem ntau ntawm lub qag nram qab, qhov uas nws txhim kho kev tuav cov lus teb thiab txo qhov tsis muaj zog thiab tawg paj. Cov tshuab tsis muaj zog hnyav dua; rau txoj kev tsheb qhov sib txawv yog qhov tau, tab sis rau cov tsheb khiav chasing lub sij hawm titanium yog cov khoom uas txav tus lej.

Thaum tshav kub kub Resistance

Titanium melts ntawm 1668℃thiab ua kom muaj zog muaj zog ntawm qhov kub thiab txias, thaum stainless hlau melts nyob ib ncig ntawm 1400-1530℃thiab softens ua ntej nyob rau hauv load. Titanium qhov qis thermal conductivity (16-21 W / m·K piv txog 15-16 W / m·K rau austenitic stainless) txhais tau tias tsawg dua cov cua sov mus txog ib puag ncig cov khoom, uas pab tiv thaiv cov xov hlau, roj kab, thiab cov vaj huam sib luag hauv qab. Ob qho khoom siv ntsuas qhov kub thiab txias; titanium ntxiv cov npoo rau kev ua haujlwm siab ua haujlwm siab.

Corrosion thiab Durability

Titanium yog qhov tseem ceeb tiv thaiv xeb: nws tus kheej- kho oxide zaj duab xis tiv thaiv txoj kev ntsev, dej hiav txwv, thiab tso pa tawm, yog li kev siv ntug hiav txwv thiab lub caij ntuj no yuav tsum tsis muaj kev saib xyuas tshwj xeeb. Stainless hlau cia siab rau ntawm chromium oxide zaj duab xis; 304 austenitic stainless muab kev tiv thaiv muaj zog, thaum 409 ferritic stainless, feem ntau hauv OEM systems, muaj tsawg dua. Hauv ntsev-siv huab cua, cov tshuab tsis muaj txiaj ntsig tau txais txiaj ntsig los ntawm kev yaug hauv qab lub cev, tshwj xeeb tshaj yog nyob rau hauv welds thiab hangers, uas yog thawj cov ntsiab lus rau corrode.

Lub zog thiab cuam tshuam tus cwj pwm

Ob qho khoom siv muaj zog txaus rau lub luag haujlwm, tab sis lawv txawv ntawm qhov toughness. Stainless hlau yog ductile thiab zam txim: nws dents es tsis tawg thiab yuav kho tau yooj yim TIG vuam. Titanium, tshwj xeeb tshaj yog nyob rau hauv nyias- phab ntsa daim ntawv, yog rhiab heev rau kev cuam tshuam thiab tuaj yeem tawg thaum ntaus sharply. Rau cov tsheb uas tau tsav ntawm pob zeb, curbs, lossis tawm - txoj kev, stainless hlau yog qhov kev xaiv muaj zog dua; rau du - tsheb kev ua tau zoo, titanium lub fragility tsis tshua muaj teeb meem.

Suab

Khoom siv, phab ntsa thickness, thiab muffler tsim txhua yam zoo li daim ntawv. Titanium systems feem ntau tsim ntau dua - suab, nws yog xim hlau, sib tw- suab nrov; stainless hlau nyhav rau ib tug ntxaum, richer tone. Vim hais tias kev ntim khoom thiab resonator tsim yeej lub suab nrov, tib txoj kev txhim khu kev qha xaiv los ntawm lub suab yog mloog qhov tseeb ntawm lub tsheb.

Qhov tshwm sim

Thaum tshav kub kub lub voj voog muab titanium xiav -ntsuab-kub kub-tint uas yog qhov kos npe lees paub ntawm cov pa zoo tshaj plaws. Stainless hlau muaj qhov huv, ruaj khov ci tiav uas tuaj yeem polished lossis coated. Yog tias qhov pom ntawm qhov tsim yog qhov yuav tsum tau ua, titanium xa cov nyhuv tsis muaj txheej; stainless muab ib tug subtler saib uas muaj hnub nyoog kwv yees.

Tus nqi thiab tus nqi

titanium raw khoom raug nqi ntau zaus ntau dua li cov hlau tsis muaj steel, thiab kev tsim khoom ntxiv cov nqi ntxiv: argon shielding, qeeb weld mus ncig, thiab cov cuab yeej siv siab. Ib qho titanium tso tawm feem ntau raug nqi ob mus rau peb npaug ntawm qhov sib piv tsis zoo. Tus nqi sib npaug yog nyob ntawm kev siv: rau lub tsheb khiav tsheb, qhov hnyav txuag thiab cov cua sov ua kom pom tseeb tus nqi; rau tus neeg tsav tsheb niaj hnub lossis kev tsim nyiaj txiag, stainless hlau xa tawm feem ntau ntawm cov txiaj ntsig kev ua haujlwm ntawm ib feem ntawm tus nqi.

Yuav txiav txim li cas

Xaiv titanium thaum txo qhov hnyav, kev tswj xyuas kub, kev tiv thaiv corrosion hauv cov ntsev lossis cov kev pabcuam ntug dej hiav txwv, thiab cov cua sov-tint saib yog tsim nyog ob mus rau peb npaug ntawm tus nqi, thiab thaum muaj kev pheej hmoo tsawg. Xaiv cov hlau tsis muaj hlau thaum siv nyiaj, cuam tshuam qhov hnyav, kho, thiab lub suab sib sib zog nqus tseem ceeb dua, lossis rau txhua hnub thiab txhua lub caij siv - lub caij. Yam khoom twg raug xaiv, paub meej tias cov phab ntsa tuab, khoov zoo, thiab cov khoom siv muffler, vim tias cov ntsiab lus no txiav txim siab lub suab thiab lub neej ntev npaum li cov khoom siv nws tus kheej.

Cov lus nug nquag

Qhov hnyav npaum li cas ntawm titanium tso tseg?

Txog 40-45 feem pua ​​​​piv nrog stainless hlau ntawm tib phab ntsa tuab, ua tsaug rau titanium 4.51 g / cm³ ntom tiv thaiv roughly 7.9 g / cm³ rau stainless.

Puas yuav titanium tso tawm xeb?

No. Titanium's oxide zaj duab xis tiv thaiv xeb, txoj kev ntsev, thiab condensate. Nws yog qhov qis tshaj - kev xaiv tu hauv qhov chaw corrosive.

Puas yog stainless hlau tso tawm muaj zog dua titanium?

Nyob rau hauv cov nqe lus ntawm yield zog, ob yog sib piv nyob rau hauv cov chav kawm, tab sis stainless hlau yog tougher nyob rau hauv kev cuam tshuam thiab yooj yim rau kho. Titanium muaj lub zog tshwj xeeb dua thiab ua kom sov zoo dua.

titanium thiab stainless hlau puas tuaj yeem welded ua ke?

Direct vuam cov ntaub ntawv brittle intermetallic theem thiab zam. Mixed- cov khoom siv tshuab siv cov khoom sib txuas lossis cov khoom hloov pauv.

Vim li cas titanium tso tawm thiaj li kim?

Titanium hlau yog kim heev los tsim (Kroll txo thiab lub tshuab nqus tsev melting), thiab cov khoom siv hluav taws xob xav tau argon shielding thiab cov cuab yeej tshwj xeeb. Ob leeg pab txhawb rau ob - rau - peb - lub sij hawm tus nqi hwm.

Cov khoom siv hluav taws xob twg siv tau ntev dua?

Hauv kev pabcuam corrosive, titanium kav ntev dua vim nws tsis tuaj yeem xeb. Hauv kev cuam tshuam - kev pabcuam yooj yim, stainless hlau muaj sia nyob zoo dua. Nrog kev saib xyuas tsim nyog, ob qho tib si tuaj yeem kav lub neej ntawm lub tsheb.
