Puas yog Inconel kim dua titanium?
Txhua yam khoom siv hauv maus taus tso tawm yog ua raws li nws cov khoom ntuj tsim thiab kev tsim nyog rau kev tshawb fawb. Titanium, stainless hlau thiab Inconel yog cov ntaub ntawv tshwj xeeb nrog cov khoom tshwj xeeb uas ua rau lawv tsim nyog rau kev siv raws li kev ruaj ntseg tshuaj, toughness, hnyav thiab kub tsis kam.
Ntawm no peb yuav piav qhia txog cov yam ntxwv tseem ceeb, kev siv thiab kev tsim khoom ntawm cov khoom sib txawv kom qhov sib txawv ntawm stainless hlau, titanium thiab Inconel pom tseeb.
titanium
Paub txog nws lub zog-rau-hnyav piv, cov hlau no yog qhov ua haujlwm zoo rau kev siv qis qis xws li kev sib tw. Titanium yog ib nrab ntawm qhov hnyav ntawm hlau tab sis sib npaug ntawm lub zog. Titanium yog kim dua hlau thiab txhuas, tab sis pheej yig dua Inconel.
Nyob rau hauv chav tsev kub, tsis muaj cov tshuaj tiv thaiv ntawm titanium, noo noo thiab oxygen. Titanium thiab Inconel zoo sib xws nyob rau hauv cov nqe lus ntawm cov ntaub ntawv tiv thaiv nyob rau hauv uas lawv tsim ib tug tiv thaiv, passivating oxidized nto txheej ntawm cov khoom. Qhov no yog vim li cas titanium muaj zog corrosion kuj. Txawm nyob hauv lub ntsej muag ntawm hydrochloric acid thiab sulfuric acid, titanium tuaj yeem tiv taus!
Tsis tas li ntawd, titanium cools sai sai, yog li thaum siv rau hauv maus taus qhov chaw xws li tso pa tawm, nws yuav tsis deform nyob rau hauv xws li kub kub.
Muaj cov khoom lag luam ntshiab titanium thiab titanium alloys ntawm lub khw. Tus qauv titanium alloy feem ntau tsim siv vanadium thiab txhuas yog Ti 6AI-4V. Qhov no suav nrog ib nrab ntawm kev siv titanium alloy thoob ntiaj teb. Cov qauv no muaj lub zog ntau dua thiab tawv dua li cov titanium ntshiab thiab yooj yim rau tshuab. Kev lag luam ntshiab titanium, thaum tiv taus corrosion, yog hloov tau yooj yim dua thiab yas dua li nws cov alloys.
Cov txheej txheem titanium
titanium alloys kuj undergo complex hardening txheej txheem, ua rau lawv nyuaj rau tshuab. Kev lag luam ntshiab titanium yog nplaum thiab tuaj yeem ua rau cov chips ntev thaum txiav, uas tuaj yeem ua rau cov cuab yeej txiav. Qhov no yog vim li cas tee kuj tuaj yeem tshwm sim thaum lub sij hawm titanium machining. Tab sis nrog lub siab txias txias, cov chips tuaj yeem raug tshem tawm thaum txiav thiab cov khoom siv tuaj yeem txav tau yooj yim dua, ua rau nws tsis yooj yim dua.
Luv luv, cuam tshuam kev txiav yuav tsum zam thaum machining titanium; cov cuab yeej txiav yuav tsum ua haujlwm txuas ntxiv thaum lawv ntsib cov khoom siv raw. Kev sib cuag ntawm cov cuab yeej ntau dhau tuaj yeem ua rau muaj kev sib txhuam, uas tuaj yeem ua rau kub dhau thiab ua rau kev ua haujlwm nyuaj. Tsawg ceev thiab cov nqi pub ntau dua yuav txo cov cua sov tsim.
Kev ua cov ntaub ntawv titanium raw khoom yuav tsum tau teeb tsa lub tshuab nruj thiab ruaj ntseg tuav. Vim li cas? Titanium thiab titanium alloys yog cov ductile heev, muaj peev xwm muaj kev sib tham thiab caij nplooj ntoos hlav thaum txiav, thiab tuaj yeem tsim qhov tsawg dua qhov ua tiav.
welded titanium
Vuam titanium thiab titanium alloys yog ib qho yooj yim. Tib txoj kev vuam siv rau cov hlau tsis muaj steel kuj siv rau titanium.
Tab sis ntawm no, kev huv huv thiab kev tiv thaiv roj inert yog qhov tseem ceeb. Cov pa phem tuaj yeem ua rau muaj teeb meem nrog titanium vuam.
Titanium siv
Lub aerospace thiab automotive industries siv titanium rau nws impressive zog-rau-qhov hnyav piv. 50% ntawm cov alloys siv hauv aerospace engineering yog Ti 6AI-4V. Cov maus taus siv titanium rau lawv cov pa tawm vim nws lub teeb yuag, tswj cov cua sov kom zoo, thiab tuaj yeem muaj xim zoo nkauj.
Titanium yog tsim rau:
nkoj naval
Khoom siv ncaws pob
Kev kho mob kev lag luam
tsaws iav
missile thiab lwm yam.
Inconel
Lub npe lag luam rau cov khoom zoo nickel-chromium alloys yog Inconel. Cov khoom siv no tuaj yeem tiv taus cov alloy-hom kub kub (txog 2, 000 degree F) nrog xoom lub zog poob. Cov khoom no yog qhov tsim nyog heev txawm tias qhov kub thiab txias.
Cov khoom siv kho tshuab ntawm Inconel ntawm chav tsev kub yog qhov zoo heev. Yog li koj paub, Inconel qib 725 muaj lub zog tensile ntawm txog 180 ksi; uas yog ob zaug lub zog ntawm cov qauv hlau. Lwm cov alloys, xws li Inconel 718, yog toughened los tiv thaiv los nag, ua rau lawv muaj zog. Corrosion thiab nws cov kwv tij: Corrosion, oxidation, corrosion cracking thiab crevice corrosion tsis cuam tshuam rau Inconel.
Inconel cov khoom zoo heev ua tau raws li cov kev xav tau ntawm cov ntawv thov. Txawm li cas los xij, cov ntaub ntawv zoo li Inconel kim dua titanium, stainless hlau, thiab txhuas.
Machining Inconel
Vim nws lub zog siab, kev ua haujlwm yog qhov nyuaj. Inconel nyuaj heev uas cov cuab yeej txiav tuaj yeem ua puas thaum lub tshuab ua haujlwm thiab cov khoom tuaj yeem sib tw thiab khoov.
Immersing Inconel nyob rau hauv ib qho kev daws yuav txo cov khoom hardness thiab tiv thaiv kev txiav cov cuab yeej hnav. Rau machining Inconel, cov cuab yeej ceramic raug pom zoo vim nws muab kev txiav nrawm thiab tsis muaj kev cuam tshuam, ua rau kev ua haujlwm tau zoo dua. Pecking yuav tsum zam vim qhov no tuaj yeem ua rau txoj haujlwm nyuaj.
Vuam Inconel
Inconel tsis yooj yim rau vuam vim tawg. Tab sis Inconel alloys tuaj yeem welded zoo li Inconel 625 - alloy uas yooj yim sau sai thiab feem ntau welded siv tungsten inert gas (TIG). Cov txheej txheem vuam no feem ntau tsis tas yuav muab tub lim tab sis ua haujlwm zoo rau kev koom nrog Inconel. Yog vim li cas thiaj pom zoo.
Kev siv Inconel
Inconel yog cov khoom ntawm kev xaiv thaum kub hnyav thiab corrosion yog teeb meem, tshwj xeeb tshaj yog thaum lwm cov hlau tsis resistant rau oxidation thiab deformation los ntawm kub kub.
Inconel muaj qhov kub thiab txias thiab tshuaj tiv thaiv zoo heev thiab yog siv rau hauv cov tshuab tso pa rau kev sib tw tsheb, turbines, dav hlau cav, thiab hauv cov roj thiab roj, aerospace, thiab marine sectors uas yuav tsum muaj cov tshuab hnyav.
