- Thaj chaw tshav kub me me: Nws muaj cov txiaj ntsig me me ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm FC020, uas tuaj yeem txo cov qauv hluav taws xob (xws li martensite).
- Tsis muaj kev sib cuag: nws yog qhov tsim nyog rau cov khoom ntiag tug (xws li Sintd10) kom txo qis kev ntxhov siab, tab sis saib xyuas yuav tsum tau them rau cov kev ruaj ntseg ntawm lub pas dej ruaj khov ntawm Molten pas.
2.}} tso tawm ntawm laser vuam ntawm FC0208 (Grey cam khwb cia hlau)
Cov nyom:
- Cov ntsiab lus muaj roj carbonies: tau yooj yim rau cov tawv thiab muaj martensite, ua kom txias tawg riins .
- Graphitizing ntsiab: Vuam tshav kub tuaj yeem rhuav tshem graphite faib thiab cuam tshuam rau kev ua haujlwm .
Lus teb
- Preheating thiab qeeb cua txias: preheat rau 300 ~ 400℃ua ntej kev siv tshuab cua txias (thiab siv cov ntawv cog zeb cua txias) tom qab vuam .
- Kev Xaiv Cov Khoom Siv: Siv npib tsib xee-raws eni-raws enibit pupbon diffusion thiab txo cov kab nrib pleb
- Txhim kho cov txheej txheem tsis muaj: Siv lub zog qis thiab qeeb ceev kom txo cov tswv yim tshav kub thiab tsis txhob muaj cua sov inheathing .
3.}} tso tawm ntawm laser vuam ntawm Sintd10 (hlau-tooj liab li alloy)
Kev sib tw
Qhov sib txawv loj hauv cov ntsiab lus melting
: Hlau (1538 degree) thiab tooj liab (1083 degree) yog qhov tsis sib luag thiab tooj liab cais .
Porosity
: Cov hws sib tw meuav me me yuav ua rau muaj qhov hws lossis tsis sib xws .
Kev daws:
- Txheej Txheem Parameter Optimization:
Siv mem tes laser hom kom thiaj li txo tus tooj liab evaporation; kho qhov chaw seem kom sib npaug ntawm cov hlau-tooj liab yaj piv rau .
- Kev Tiv Thaiv Pauv Roj:
Siv Argon lossis Helium los tshuab ntshav kom tiv thaiv palees .
- Pretricatment:
Ua tau kub ostatic nias (hip) descification kho ua ntej vuam, lossis xaiv lub zog loj laser (xws li fiber ntau laser) kom kaw cov pores .
4. laser vuam ntawm cov ntaub ntawv tsis sib xws ntawm FC0208 thiab Sintd10
Kev sib tw: Metallurgical Mismatch:
Brittle Intermetallic cov lus sib txuas (xws li Fe-Cu) tau yooj yim tsim ntawm tus hlau-tooj liab interface.
Qhov sib txawv hauv Kev Tshaj Tawm Termal Kev nthuav tawm:
Ua rau vuam kev nyuaj siab .
Kev daws:
- Intermediation Txheej Kev Hloov: Ntxiv cov nyiaj npib tsib xee los yog xws li nickel lossis bronze lossis tooj daj) rau undeviate interfund {}}
- Composite: Laser thiab Arc Composite vuam los txo cov tswv yim tshav kub thiab txhim kho lub cev muaj roj moltent {}}
- Kev Kho Mob Tom Qab Weld: Kev Kho Mob Tawm (500 ~
5.} Kev ceev faj
Ntxuav tu: kom huv si tshem cov roj, oxides, thiab zam kom tsis txhob muaj qhov hws (saib cov ntawv sau daws teeb meem 3).
Cov cuab yeej xaiv: Fiber laser yog qhov zoo dua, nrog lub zog siab ntom ntom thiab ruaj khov Beam zoo {}}
Kev soj ntsuam zoo: Ultrasonic lossis X-ray Qhov kev pom tau raug kuaj pom tau yog siv los tshawb xyuas cov kev ntsuas kev sib tw sab hauv, ua ke nrog kev sib xyaw ntawm cov qauv .
Tag
Laser Vuam ntawm FC0208 thiab Sintd10 yog ua tau, tab sis cov txheej txheem yuav tsum tau ua kom zoo raws li cov yam ntxwv cov khoom:
FC0208: Rov ua kom sov, qeeb thiab npib tsib xee-raws li cov ntaub ntawv yuav tsum tswj cov tswv yim tshav kub.
Sintd10Sint-D10 yog hmoov metallurgy cov khoom ntawm German tus qauv
: Txhim kho cov Laser tsis zoo, descification pretricatment, thiab inhibit tooj liab segregation .
Dissimilar Vuam
: Tso cai rau cov txheej txheem sib tshooj thiab cov txheej txheem sib xyaw ua kom ntseeg tau tias interface metallurgical compatibility .
Nws raug nquahu kom paub tseeb cov txheej txheem tsis raug los ntawm kev sim thiab ntsuas qhov kev ua tau zoo ntawm welded ua ke nrog microstretreure kev tsom xam (eds) .
