Taw qhia: Thaum "pob foob pob" thiab "micro sandpaper" sib koom ua ke, qhov kev tiv thaiv twg tuaj yeem ua tsis tau?
Ntawm qhov chaw nres nkoj ntawm qhov siab - siab sib txawv tswj lub valve thiab cov hniav saum npoo ntawm lub siab- lub twj tso kua mis ceev, lub pob valve tau raug rau ob qho kev puas tsuaj rau lub cev:cavitation thiab hnav. Cavitation - super-siab siab micro- dav hlau poob siab nthwv dej uas tsim los ntawm qhov tawg sai sai ntawm cov npuas hauv cov kua dej, zoo li suav tsis txheeb cov foob pob me me tsis tu ncua foob pob zeb; hnav - txiav thiab plowing ntawm cov khoom tawv hauv nruab nrab. Ob qho no feem ntau ua hauv kev hais kwv txhiaj, ua kom puas tsuaj sai sai. Ib txheej txheej txheej txheem ib leeg tsis tuaj yeem tiv taus lawv, thiab kev lag luam tab tom hloov mus rau qhov tseeb daim ntawv thov eraHVOF thiab txias txauthiab lwm yam - tiam dense txheej technologies.Tongball, raws li ib tug pioneer nyob rau hauv nto engineering, tsis tsuas yog masters ob lub technologies siab heev tab sis kuj siv zog ua kom haum rau qhov zoo "defenders" rau ntau hom tsis ua hauj lwm los ntawm kev sib piv kev tshawb fawb.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: "Birth Philosophy" thiab Kev Ua Haujlwm Profiles ntawm Ob Qhov Ultra- Txheej Txheej
HVOF thiab cov tshuaj tsuag txias ob lub hom phiaj npaj siab - ntom thiab siab - sib khi quab yuam txheej, tab sis lawv cov ntsiab lus tseem ceeb sib txawv, yog li lawv cov yam ntxwv ua tau zoo thiab cov xwm txheej ntawm daim ntawv thov yog qhov tshwj xeeb.
1. Siab-Speed Oxygen Fuel Spraying (HVOF): "Forging Art" ntawm Thermal Energy thiab Kinetic Energy
Lub hauv paus ntsiab lus:Cov roj thiab oxygen combustion tsim supersonic nplaim taws, cua sov cov hmoov rausemi-molten los yog tag nrho molten lub xeev, thiab cuam tshuam rau lub substrate ntawm kev kub ceev heev, tsim ib txheej los ntawm cov yas deformation.
Core Advantages:
Tsis tshua muaj siab hardness thiab hnav tsis kam:Cov hmoov yog tag nrho melted, tsim ib tug tag nrho alloyed txheej qauv, tshwj xeeb tshaj yog hlau ceramic txheej xws li tungsten carbide, nrog ib tug hardness ntawm tshaj HV1200, ua ib tug benchmark rau resisting abrasive hnav.
Kev ua haujlwm zoo heev rau siab -Tub kub Oxidation thiab Corrosion:Cov txheej yog ntom, nrog ruaj khov siab -kub theem, haum rau yaig tej yam kev mob nrog hais hauv qab 900 degree.
Muaj peev xwm txwv:Kev kub siab - txheej txheem yuav ua rau cov ntaub ntawv rhiab heev (xws li carbides) kom decompose, oxidize, thiab qhia oxide inclusions thiab thermal stress. Qhov no yuav ua rau muaj teeb meem rau kev tiv thaiv -cov kab mob ntshiab huv uas xav tau cov tshuaj purity siab heev thiab kev ntxhov siab tsawg heev.
2. Txias Txias (Txias Txias): "Kev Tsim Kho Kev Tshawb Fawb" ntawm Pure Kinetic Solid Deposition
Lub hauv paus ntsiab lus:Siv preheated siab - siab roj (helium, nitrogen) kom ceev cov hmoov particle mus rausupersonic ceev (txog 1200 m / s), nrog rau qhov kub thiab txias deb ntawm lawv cov ntsiab lus melting, ua tiav metallurgical bonding los ntawm khaus yas deformation ntawm cov khoom cuam tshuam rau lub substrate.
Core Advantages:
Tsis muaj kev cuam tshuam thermal, khoom vaj khoom tsev tsis cuam tshuam:Tag nrho cov txheej txheem yog nyob rau ntawm qhov kub thiab txias, zoo kawg nkaus zam oxidation, theem hloov, decomposition los yog grain loj hlob ntawm cov khoom. Qhov no yog ib qho tseem ceeb technology rauTongballlos khaws cov khoom qub zoo heev (xws li conductivity, corrosion resistance) ntawm ntshiab tooj liab, titanium, thiab rhiab alloys.
Muaj Peev Xwm Zoo rau Kev Tiv Thaiv -Cavitation Performance:Cov txheej txheej tsim tsis muaj oxide inclusions, siab residual compressive kev nyuaj siab, thiab zoo toughness, muaj peev xwm ua tau zoo dua nqus thiab dissipate lub zog ntawm cavitation micro- dav hlau los ntawm yas deformation, es tsis tsim nkig tawg.
Deposition Efficiency thiab Thick Coating Capacity:Nws tuaj yeem tso cov hlau dawb huv sai sai los yog cov txheej txheem alloy los kho lossis ntxiv dag zog rau cov khoom loj.
Cov kev sib tw tam sim no:Cov kev xav tau ntawm plasticity siab heev rau cov hmoov, thiab ib txwm muaj siab - cov ntaub ntawv tawv tawv (xws li cov ceramics ntshiab) yog qhov nyuaj rau kev tso nyiaj. Lub txheej hardness feem ntau yog qis dua li cov txheej txheem tag nrho ntawm HVOF.
Tongball's Analysis thiab Selection Framework:HauvTongball covkev txiav txim siab -kev txiav txim, kev xaiv tsis yog ib qho yooj yim zoo los yog phem, tab sis raws li qhov tseeb txuam ntawm kev ua tsis tau zoo dominance hom.Thaum hnav (tshwj xeeb yog abrasive hnav) yog qhov tseem ceeb, HVOF yog tus yeej; Thaum cov ntshiab cavitation, thermal rhiab heev, los yog yuav tsum tau rau siab conductivity / thermal conductivity ntawm txheej yog tam sim no, txias txau qhia tshwj xeeb zoo. Rau kev sib xyaw ua ke ntawm cavitation thiab hnav, Tongball tab tom tshawb nrhiav qhov tshiab "txias txheej txheej + HVOF txheej txheej" gradient composite technology.
Case demonstration: Xaiv los tiv thaiv -cavitation "cov cuab yeej" rau lub supercritical dej oxidation system
Lub reactor qhov hluav taws xob tswj lub pob valve ntawm ib puag ncig tiv thaiv kev lag luam tus supercritical dej oxidation ntaus ntawv yog raug rau huab cua cavitation puas. Qhov nruab nrab yog qhov siab - kub thiab siab - cov kua dej siab uas muaj cov organic complex thiab inorganic ntsev. Ntau yam thermal spraying txheej tau raug sim, tab sis txhua yam ua tsis tiav nyob rau hauv ob peb puas teev vim lub flaking ntawm txheej txheej tshwm sim los ntawm cavitation.
Tongball txoj kev daws teeb meem thiab kev txheeb xyuas qhov sib piv:
Kev kuaj mob:CovTongballpab neeg txiav txim siab tias lub ntsiab ua rau tsis ua hauj lwm yog cov oxide inclusions thiab microcracks nyob rau hauv cov tsoos thermal spray txheej uas ua rau qaug zog qhov chaw nyob rau hauv cov kev cuam tshuam ntawm cavitation, ua rau lub internal disintegration ntawm txheej.
Kev sib piv: Tongballnpaj ob lub tswv yim: Scheme A yog HVOF txau chromium carbide txheej; Scheme B yog txias txau Inconel 625 alloy txheej.
Cov ntaub ntawv tau txais:Kev ntsuas nrawm tau ua nyob rau hauv qhov chaw simulated cavitation. Scheme A ua tau zoo thaum pib, tab sis nws qhov kev ua tau zoo pib poob qis tom qab 200 teev; Scheme B (txias txau) muaj aQhov hnyav poob tsuas yog 30% ntawm Scheme Athoob plaws lub sij hawm xeem (sib npaug rau 1500 teev nyob rau hauv lub tshav pob), thiab saum npoo yog uniform yas indentations tsis muaj tej yam tshwm sim ntawm flaking.
Kev txiav txim zaum kawg:Raws li cov ntaub ntawv,Tongballpom zoo thiab muab cov tshuaj tsuag txias Inconel 625 txheej valve pob. Lub pob valve no tau ua haujlwm ruaj khov ntawm - qhov chaw rau ntau tshaj ib xyoos, thiab nws txoj kev tiv thaiv - cavitation kev ua tau zoo tshaj qhov cov neeg siv khoom xav tau. Cov ntaub ntawv no tau tsimTongball covTxias txau tshuab hauv qhov kev xav tau tam sim no.
Kev txhim kho tus nqi: Kev sib piv kev txheeb xyuas - los ntawm "txhua yam ua haujlwm" mus rau "qhov twg yog qhov tsim nyog tshaj"
Rau cov neeg siv khoom nrhiav kev ntseeg siab kawg, kev nkag siab thiab siv qhov sib txawv ntawm HVOF thiab cov tshuab txau txias muaj txiaj ntsig zoo:
Ua kom tiav cov peev txheej:Muab cov peev txheej tsawg rau cov thev naus laus zis uas tuaj yeem daws qhov teeb meem tseem ceeb, zam "dhau-tsim" lossis "tsim tsis txaus", thiab ua tiav qhov kev ua tau zoo tshaj plaws - tus nqi piv.
Xauv lub peev xwm ntawm cov ntaub ntawv tshiab:Nrog rau kev siv tshuab txias txias, cov ntaub ntawv zoo heev (xws li qee qhov siab -entropy alloys, amorphous alloys) uas yav tas los tsis tuaj yeem siv rau cov txheej txheej vim thermal rhiab heev tuaj yeem nkag mus rau hauv cov tshuaj, qhib kev ua haujlwm tshiab.
Tsim kom muaj lub neej yav tom ntej -kev cob qhia kev cob qhia cov khoom siv:Koom tes nrog ib lub tuam txhab xws liTongballtxhais tau tias koj tuaj yeem nkag mus tsis tu ncua nkag mus rau cov tsev qiv ntawv thev naus laus zis thev naus laus zis tshaj plaws, ua kom koj cov khoom ib txwm muaj kev coj noj coj ua.
