Stellite Alloy hmoov tau tshaj Laser Cladding Technology

Raws li cov cobalt classic-raws li cov khoom siv hlau, Stellite alloy hmoov muab nws cov txiaj ntsig kev ua tau zoo los ntawm qhov tseeb muaj pes tsawg leeg piv thiab hmoov morphology tsim. Nws cov ntsiab lus tseem ceeb yog cobalt (Co) matrix, ntxiv nrog cov ntsiab lus alloying xws li chromium (Cr), tungsten (W), thiab molybdenum (Mo). Qee qib, xws li Stellite 21, muaj 27-30% chromium thiab 4.5-6% molybdenum, tsim cov qib siab carbide (piv txwv li, Cr₇C₃, M₆C) uas tso cai rau cov khoom siv tshwj xeeb hnav thiab corrosion kuj. Nws cov khoom tseem ceeb yog xav txog peb yam: ua ntej, siab - qhov kub thiab txias, tswj hardness thiab structural kev ncaj ncees ntawm 950 degree, deb tshaj cov khoom siv hlau zoo tib yam; thib ob, tag nrho -scenario corrosion kuj, nrog zoo heev tiv thaiv oxidizing acids, txo cov kua qaub, thiab chlorine-induced corrosion-Stellite Super C qib muaj kev txhim kho corrosion kuj zoo piv rau cov qib ib txwm muaj; thib peb, hmoov compatibility. Cov hmoov uas tsim los ntawm cov txheej txheem roj atomization muaj qhov zoo fluidity thiab tsis sib xws, raug txuam nrog cov txheej txheem ntawm cov txheej txheem kev kho saum npoo av xws liLaser Cladding thiab HVOF. Cov khoom no ua rau nws nyiam cov khoom siv tiv thaiv kev tiv thaiv thiab kho hauv kev ua haujlwm hnyav..

Cov kev xav tau nruj ntawm European kev tsim khoom rau siab - kev ntseeg tau thiab ntev - lub neej cov khoom tau tsav hauv - qhov tob tob ntawm Stellite alloy hmoov hauv cov lag luam tseem ceeb. Hauv aerospace sector, aviation lag luam hauv lub teb chaws Yelemees thiab Fabkis siv nws rauLaser Claddingntxiv dag zog rau turbine hniav thiab combustion chamber Cheebtsam, ua tau raws li qhov siab -kub hnav tsis kam ntawm EN 9100 aviation quality standard. Hauv kev lag luam petrochemical, roj thiab roj extraction lag luam hauv Netherlands thiab Norway tau txais cov hmoov no los kho corrosion- cov khoom siv xws li li qub thiab lub cev twj tso kua mis, tiv thaiv kev yaig los ntawm qhov tob - hiav txwv thiab tshuaj lom neeg. Kev lag luam tsheb yog lwm qhov tseem ceeb ntawm daim ntawv thov scenario: German automakers siv Stellite 6 hmoov rau kev hloov kho saum npoo ntawm lub cav valve lub rooj zaum thiab piston rings, tsim hnav- cov coatings resistant los ntawm laser cladding uas txuas ntxiv kev pab cuam lub neej los ntawm 3-5 zaug. Tsis tas li ntawd, nyob rau hauv cov teb chaws Europe precision machinery manufacturing sector, Stellite 21 hmoov yog feem ntau siv rau saum npoo hardening ntawm pwm thiab txiav cov cuab yeej, adapting rau high-precision ua xav tau kev pab ntawm lub teb chaws xws li Switzerland thiab Ltalis. Cov xwm txheej ntawm daim ntawv thov no txhua tus cia siab rau Tebchaws Europe cov txheej txheem kev lag luam nruj, qhia txog kev ua tau zoo thiab qhov kev hloov pauv ntawm Stellite alloy hmoov.

Lub meej kub tswj thiab ceev solidification yam ntxwv ntawmLaser Claddingthev naus laus zis pab kom Stellite alloy hmoov los ua ib qho siab - zog metallurgical daim ntawv cog lus nrog substrate. Kev tshawb fawb qhia tau hais tias nyob rau hauv optimized laser tsis (piv txwv li, hwj chim 1000-1500W, scanning ceev 5-10mm/s), Stellite 6 hmoov thiab H13 kub ua hauj lwm tuag steel substrate yuav ua tau ib tug interdiffusion, tsim ib tug tawg -dawb thiab tightly bonded cladding txheej nrog ib tug interfacial shearing zog. 350-450MPa-ntau tshaj qhov kev sib txuas ntawm cov txheej txheem welding zoo tib yam. Cov qib sib txawv ntawm Stellite hmoov nthuav tawm qhov sib txawv ntawm cov khoom siv hlau: Stellite 20 hmoov, nrog rau kev sib ntxiv ntawm tungsten carbide (WC), tuaj yeem ua rau cov cladding txheej hardness rau HRC 55-60, nrog rau ib txhij 15{27}}20% kev txhim kho hauv kev sib raug zoo zog; Stellite 21 hmoov, muaj cov ntsiab lus xws li npib tsib xee thiab molybdenum, tuav lub zog sib txuas siab thaum muab cov tawv tawv zoo dua thiab kev cuam tshuam. Piv nrog rau cov hlau, qhov "durability" ntawm Stellite alloy yog nyob rau hauv nws cov kev ua tau zoo zoo: nws chav - kub hardness tuaj yeem ncav cuag HRC 45-65, siab dua li cov pa roj carbon zoo tib yam (HRC 15-25), thiab nws qhov kub thiab txias hnav tsis kam thiab corrosion kuj tsis piv rau cov hlau. Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm chav tsev kub tensile lub zog, ib co high-strength steels (xws li, quenched thiab tempered steel) muaj ib tug me ntsis kom zoo dua. Yog li ntawd, kev xaiv ntawm ob yog nyob ntawm cov kev ua haujlwm tshwj xeeb-Stellite alloy yog qhov zoo dua rau kev tiv thaiv kev tiv thaiv nyob rau hauv ib puag ncig huab, thaum lub zog siab steel yog tsim rau cov khoom siv thauj khoom-cov kabmob.

Kev lag luam thoob ntiaj teb xa tawm rau Stellite alloy hmoov yog qhia txog kev loj hlob tsis tu ncua, nrog rau qhov kev npaj ua lag luam txhua xyoo (CAGR) ntawm 6-8% los ntawm 2025 txog 2030, thiab Europe yog ib qho ntawm cov neeg siv khoom lag luam tseem ceeb. Kev thov hauv European lag luam feem ntau yog los ntawm cov khoom siv tu thiab kho dua tshiab hauv tsheb, aerospace, thiab petrochemical industries, nrog rau kev tsom mus rau kev ua siab dawb huv thiab kho cov hmoov sib xyaw nrogLaser Claddingtshuab. Piv txwv li, Stellite 21 AM-cov hmoov tshwj xeeb tau tsim los ntawm Kennametal tau dhau los ua cov khoom lag luam nrov hauv Tebchaws Europe cov khoom tsim khoom ntxiv, siv rau kev kho thiab rov ua dua tshiab ntawm cov khoom siab - kawg. Stellite hmoov xa tawm mus rau Tebchaws Europe yuav tsum tau ua raws li cov qauv zoo, xws li ISO 5406 hmoov metallurgy tus qauv thiab EN 14700 vuam cov khoom specification, thiab tau txais ntawv pov thawj CE los xyuas kom meej ib puag ncig thiab kev nyab xeeb ua raws. Tuam Tshoj, Tebchaws Asmeskas, thiab Lub Tebchaws Yelemees yog lub tebchaws xa tawm tseem ceeb. Ntawm lawv, Suav cov lag luam tau maj mam nce lawv cov feem hauv nruab nrab - mus rau - siab - kev ua lag luam kawg vam khom rau cov nqi zoo thiab kev hloov kho thev naus laus zis. Txawm li cas los xij, kev sib tw ua lag luam tseem ntsib cov teeb meem, xws li kev hloov pauv ntawm cobalt raw khoom tus nqi thiab cov khoom lag luam teeb meem ntawm European cov neeg muag khoom hauv zos. Yog li ntawd, cov tuam txhab xa tawm yuav tsum tau tsom mus rau kev sib txawv ntawm cov khoom lag luam (piv txwv li, qhov sib txawv ntawm cov khoom sib txawv) thiab cov kev pab cuam (xws li, laser cladding txheej txheem kev taw qhia) kom tau raws li qhov xav tau ntawm cov neeg siv khoom nyob sab Europe.
