Thaum ib tug neeg hais txog Tribaloy, thawj qhov uas feem ntau los rau hauv lub siab tsuas yog 'qhov nyuaj cobalt alloy'. Tab sis qhov ntawd yog qhov yooj yim me ntsis uas tuaj yeem coj koj mus rau txoj hauv kev tsis ncaj ncees thaum lub sijhawm tsim lossis kev tsim khoom. Nws tsis yog hais txog hardness xwb; nws yog hais txog qhov tshwj xeeb ua ke ntawm galling kuj, corrosion kuj, thiab tswj cov khoom ntawm kub kub. Kuv tau pom cov phiaj xwm kaw vim qhov spec nyuam qhuav hu rau 'Tribaloy' yam tsis tau qhia txog qib-T-400, T-800, T-800C-lawv coj txawv txawv. Lub siab cobalt thiab molybdenum cov ntsiab lus nrog Laves theem qauv yog tus yuam sij, tab sis yuav ua li cas nws ua tiav ua los yog ua txhaum ib feem.
Qhov tseeb ntawm Machining thiab Forming
Cia peb ncaj nraim mus rau qhov mob taw tes: machining Tribaloy yog dais. Nws yog feem ntau muab los ua ib qho casting, uas yog txoj hauv kev nkag siab mus rau cov duab nyuaj. Sim tshuab nws los ntawm wrought bar nrog cov cuab yeej carbide txheem yog ib txoj hauv kev ceev kom hlawv los ntawm koj cov peev nyiaj thiab kev puas tsuaj. Cov khoom ua hauj lwm hardens aggressively. Koj muab txiav, thiab qhov chaw koj nyuam qhuav dhau los ua nyuaj dua. Peb tau kawm ntxov tias koj xav tau kev teeb tsa nruj, qhov zoo rake geometries, thiab qee zaum txawm tias mus rau kev sib tsoo lossis EDM rau qhov tseem ceeb rau kev zam. Nws tsis yog 'tshuab nws ceev' cov khoom; nws yog 'machine nws ntse' ib qho. Coolant flow yog tsis-negotiable-thiab tsis yog rau txias, tab sis tiv thaiv micro-welding ntawm chips.
Qhov no yog qhov kev koom tes nrog lub chaw tsim khoom uas paub txog nws cov khoom tseem ceeb. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb lub xyoo caum nyob rau hauv lub plhaub thiab peev casting rau tshwj xeeb alloys, muaj cov patternmaking thiab cov txheej txheem tswj kom tau lub casting ze rau net zoo. Qhov ntawd yog ib nrab ntawm kev sib ntaus sib tua yeej. Koj xav tau me ntsis tom qab nrum machining li sai tau. Kuv nco qab txog lub rooj zaum lub nplhaib qhov project qhov chaw pib kos duab hu ua Tribaloy T-400 block kom hollowed. Cov nqi machining yog astronomical. Peb redesigned nws nrog QSY los ua ib tug ze-net-shaped peev casting, uas txiav lub sij hawm machining li ntawm 70%. Lawv cov kev paub nrog kev pub mis thiab solidification ntawm cov cobalt-raws li alloys tiv thaiv shrinkage porosity nyob rau hauv lub ntsej muag tseem ceeb.
Vuam los yog brazing Tribaloy mus rau lub substrate, zoo li hlau, rau ib feem ntawm clad yog lwm daim ntawv thov. Ntawm no, qhov tsis sib haum xeeb hauv thermal expansion nrog lub hauv paus hlau yog tus neeg tua neeg uas ntsiag to. Yog hais tias tus txheej txheem tsis raug hu rau hauv-preheat, interpass temp, ib tug tshwj xeeb muab tub lim zoo li Stellite 6 los yog ib tug npib tsib xee-raws li alloy-koj tau tawg. Tsis yog ib txwm tam sim ntawd, tab sis tom qab ob peb lub voj voog thermal hauv kev pabcuam. Nws yog hom tsis ua haujlwm classic. Txoj kab kev ncaj ncees yog txhua yam. Peb tau muaj kev vam meej nrog lub tshuab nqus tsev brazing rau qee qhov kev ntseeg siab hauv aerospace, tab sis nws yog txheej txheem uas xav tau kev huv huv thiab tsim kho kom zoo.
Qib Xaiv: Tsis yog T-400 xwb
Feem ntau cov neeg ua txhaum cai rau T-400. Nws yog lub workhorse, zoo tagnrho-ncig hnav tsis kam. Tab sis yog tias koj nyob rau hauv ib puag ncig corrosive heev, hais nrog chlorides lossis acids, T-800 nrog nws cov ntsiab lus chromium siab dua yog qhov zoo dua thawj koom ruam. Kev lag luam tawm? Ib txhia hais tias nws tsis tshua muaj zog dua T-400, tab sis nyob rau hauv ib tug corrosive-coj qhov teeb meem, nws yuav outlast T-400 los ntawm ib tug dav margin. T-800C ntxiv cov pa roj carbon rau kev puas tsuaj zoo dua, tab sis saib xyuas qhov brittleness hauv cov xwm txheej cuam tshuam. Koj yuav tsum phim cov qib mus rau qhov kev pabcuam tiag tiag, tsis yog cov lus piav qhia hauv phau ntawv xwb.
Kuv tau koom nrog hauv daim ntawv thov lub tes tsho rau lub tshuab ua tshuaj. Tus thawj spec yog T-400. Nws ua tsis tiav nyob rau hauv lub hlis vim pitting corrosion ua ke nrog abrasive slurry hnav. Peb tau hloov mus rau lub tes tsho T-800, tau txais los ua cov khoom siv pov tseg kom muaj kev ruaj ntseg ntawm cov phab ntsa nyias, thiab lub neej ntev tau nce los ntawm plaub. Tus nqi ntawm cov khoom pib yog siab dua, tab sis tag nrho cov nqi ntawm ib teev ua haujlwm poob qis. Qhov no yog hom kev tsim khoom muaj nqis uas yog los ntawm cov khoom siv, tsis yog cov ntaub ntawv xwb.
Lwm nuance yog lub microstructure ntawm casting. Cov txheej txheem tswj tau zoo los ntawm cov kws tsim khoom tshwj xeeb yuav tsum ua kom muaj qhov sib txawv ntawm qhov nyuaj Laves theem hauv cobalt matrix. Kuv tau pom tsis zoo nrum Tribaloy qhov twg Laves theem yog pawg, tsim cov cheeb tsam tsis muaj zog thiab pib tawg tawg. Qhov no tsis yog qhov tsis xws luag uas koj tuaj yeem pom tau yooj yim nrog kev kuaj pom qhov pom; nws yuav xav tau kev tshuaj xyuas metallographic. Thaum koj tab tom nrhiav, koj tsis yog yuav cov hlau xwb, koj tab tom yuav qhov sib xws ntawm cov txheej txheem tom qab nws.
Application Pitfalls thiab Real-World Fixes
Daim ntawv thov classic rau Tribaloy alloy qhov chaw yog nyob rau hauv qhov chaw hnav: bushings, seals, valve rooj, lub tes tsho twj tso kua mis. Tab sis ib qho yuam kev feem ntau yog siv nws txhua qhov chaw hauv kev sib dhos. Nws kim. Tus tsim ntse siv nws tsuas yog qhov chaw hnav hnyav lossis khaus tshwm sim, feem ntau raws li kev ntxig lossis cov welded overlay. Tsim cov vaj tsev lossis cov mating ib feem los ntawm ib yam dab tsi ntau dua machinable, xws li 316 stainless, thiab tom qab ntawd nias-fitting los yog khi rau Tribaloy insert yog tus qauv xyaum.
Thermal expansion tom neeg ntawm no ib yam nkaus thiab. Yog tias koj tsim cov xovxwm nruj-haum ntawm chav tsev kub, nws puas yuav xoob lossis dhau-stressed ntawm kev ua haujlwm kub? Koj yuav tsum ua lej. Peb muaj ib rooj plaub nrog lub siab kub tshuab ziab khaub ncaws. Lub tes tsho Tribaloy tau haum rau hauv lub tsev steel. Thaum ambient, qhov haum yog zoo meej. Ntawm 500 ° C, cov hlau tau nthuav dav ntau dua li Tribaloy, ua rau poob ntawm kev cuam tshuam thiab qhov kawg ntawm lub tes tsho. Kev txhim kho yog los hloov qhov kev xam kom haum raws li qhov ntsuas kub ntawm kev ua haujlwm, tsis yog kev sib dhos kub, thiab siv cov khoom siv hluav taws xob kub kom ruaj khov ua cov thaub qab.
Kev ua tiav yog lwm qhov nthuav dav. Rau sealing nto, koj feem ntau xav tau ib qho zoo kawg nkaus. Kev sib tsoo yog ua tau tab sis qeeb. Qee zaum, lapping yog kauj ruam kawg. Lub hom phiaj tsis tas yuav yog daim iav tiav, tab sis qhov sib xws, qhov chaw tiaj tus uas yuav tsis tawm tsam nws tus khub. Rau qee cov ntsaws ruaj ruaj, peb tau txawm teev cov txheej ntxeem me ntsis rau saum Tribaloy kom khaws cov roj nplua nyeem - tab sis qhov ntawd yog tag nrho lwm cov txheej txheem tshwj xeeb.
Sourcing thiab Supply Chain Reality
Koj tsis tsuas yog xaj Tribaloy qhov chaw los ntawm cov ntawv teev npe zoo li koj xav tau 304 stainless brackets. Nws yog ib qho qis-ntim, muaj txiaj ntsig tshwj xeeb. Lub sij hawm txhuas yog ntev, tshwj xeeb tshaj yog tias koj xav tau kev cai castings. Raw alloy ingot nws tus kheej yog cov khoom siv tswj. Qhov no yog vim li cas kev tsim kev sib raug zoo nrog tus neeg muag khoom muaj peev xwm yog ntau ntawm kev sib koom tes. Lawv dhau los ua qhov txuas ntxiv ntawm koj pab pawg engineering.
Ib lub tuam txhab zoo li QSY (koj tuaj yeem pom lawv lub peev xwm ntawm https://www.tsingtaocnc.com) ua piv txwv tus qauv no. Lawv cov keeb kwm ntev hauv casting thiab machining tshwj xeeb alloys txhais tau tias lawv tuaj yeem qhia txog kev tsim khoom ntawm tus qauv tsim los ntawm qhov pib. Lawv tsis yog lub khw muag khoom xwb; lawv to taub qhov metallurgy los ntawm lub cub tawg mus rau. Rau qhov tsis ntev los no aerospace actuator tivthaiv, peb tau dhau los ntawm peb qhov kev hloov pauv hloov pauv nrog lawv - kho qhov chaw ntawm lub rooj vag ntawm tus qauv siv quav ciab, tweaking kev kho cua sov tsis-ua ntej peb kaw cov txheej txheem rau kev tsim khoom. Qhov kev sib koom tes yog qhov ua kom ntseeg tau Tribaloy qhov chaw ua tau nyob rau hauv daim teb.
Lwm txoj hauv kev - mus nrog tus nqi pheej yig tshaj los ntawm lub khw muag khoom siv dav dav uas tsuas yog yuav Tribaloy bar Tshuag - yuav luag ib txwm muaj kev lag luam cuav. Lawv yuav tawm tsam nrog machining, qhov kev tsis lees paub yuav siab, lub sij hawm txhuas yuav tshuab tawm, thiab koj yuav xaus nrog ib feem uas muaj kev ntxhov siab los yog micro-kawg uas ua rau ua tsis tiav ntxov. Tus nqi tag nrho ntawm kev ua tswv cuab yog nyob rau hauv kev ntseeg tau, tsis yog tus nqi tsev ntawm PO.
Xaus Kev Xav: Nws yog Kev Ua Si Tshwj Xeeb
Thaum kawg, ua hauj lwm nrog Tribaloy tsis yog ib yam dab tsi uas koj dabble nyob rau hauv. Cov dab neeg ua tiav yog los ntawm kev xav hauv kev sib koom ua ke: tsim rau kev tsim khoom (nyiam dua casting), xaiv qib raug, kev tswj xyuas cov txheej txheem zoo, thiab tus khub muab khoom uas tau txais. Nws tsis yog khoom.
Qhov ua tsis tiav, hauv kuv qhov kev paub dhau los, feem ntau taug qab rov qab los kho nws zoo li ib qho - sim txuag ob peb las rau pem hauv ntej kawg los ntawm kev cuam tshuam ntawm tus txheej txheem lossis tus neeg muag khoom. Thaum nws ua haujlwm, txawm li cas los xij, nws daws teeb meem uas yuav luag tsis muaj lwm yam khoom siv tau. Ib qho khoom siv Tribaloy ua tau zoo hauv daim ntawv thov raug yog qee yam koj nruab thiab tom qab ntawd tsis nco qab txog ntau xyoo, uas yog qhov kev qhuas siab tshaj plaws uas koj tuaj yeem muab ib feem.
Yog li, yog tias koj tab tom qhia nws, khawb tob dua li lub npe generic. Xav txog tag nrho lub neej voj voog: yuav ua li cas nws yuav ua, yuav ua li cas nws yuav muab tso rau hauv kev pab cuam, thiab dab tsi nws yuav ntsib nyob rau ntawd. Qhov ntawd yog qhov tiag engineering nrog cov no alloy qhov chaw tshwm sim.
