Kev kub ceev laser cladding (EHLA)yog tsim los ntawm cov pa laser cladding (CLA). EHLA thev naus laus zis siv lub zog siab laser raws li qhov cua sov, siv txoj hauv kev ntawm coaxial hmoov pub, uas muaj cov khoom zoo xws li kev puas tsuaj thiab kev tiv thaiv corrosion, thiab yaj cov hmoov rau ntawm qhov chaw ntawm qhov nrawm nrawm heev. Yog li, cov txheej txheem tiv thaiv nrog lub zog metallurgical daim ntawv cog lus, qis dilute tso tawm tus nqi thiab kev puas tsuaj zoo heev tau npaj, yog li txuas ntxiv kev pabcuam lub neej ntawm cov khoom.
Txoj cai ntawm ultra-high speed laser cladding technology
Raws li cov qauv siv tshuab laser cladding, ultra-high-speed laser cladding tshuab tuaj yeem tswj tau qhov kev faib tawm ntawm lub zog laser hauv cov txheej txheem cladding los ntawm kev ua kom zoo ntawm kev sib cuam tshuam ntawm laser, hmoov thiab matrix, thiaj li kom paub qhov zoo deposition ntawm txheej hmoov. . Piv nrog rau cov tsoos laser cladding technology, lub tsom xam ntawm lub laser thiab hmoov beam nyob rau hauv cov txheej txheem ntawm ultra-siab ceev laser cladding yog nyob rau saum npoo ntawm lub substrate, thiaj li hais tias cov txheej txheem raw cov ntaub ntawv hmoov melts ua ntej raug thauj mus rau saum npoo ntawm substrate. lub substrate, yog li ua tiav ib qho kev nce ntxiv hauv cov kab cladding ceev. Lub cladding kab ceev ntawm ultra-high-speed laser cladding tshuab tuaj yeem ncav cuag 500m / min, thiab cov txheej txheem cladding tuaj yeem ncav cuag 500cm2 / min, uas yog ntau tshaj 10 npaug ntawm cov tsoos laser cladding.
Ntawm qhov tod tes, nyob rau hauv cov txheej txheem ultra-high-speed laser cladding, li 80% ntawm lub zog laser yog siv los yaj cov hmoov kom coated. Tsuas yog 20% ntawm lub zog yog siv los ua kom sov lub substrate, thiab cov hmoov melted mus txog lub preheated substrate thiab sai sai tsim ib tug ntom txheej nrog ib tug metallurgical daim ntawv cog lus, yog li cov txheej muaj ib tug tsawg dilution tus nqi, yog li xyuas kom meej nws zoo heev hnav thiab corrosion kuj. Tsis tas li ntawd, lub zog qis ntawm lub substrate nto tuaj yeem txo cov cua sov deformation ntawm lub substrate thaum ua, yog li nws tuaj yeem siv rau kev ua cov ntawv nyias nyias thiab cov ntawv loj.

Qhov zoo ntawm ultra-siab ceev laser cladding tshuab
Piv nrog rau cov tsoos laser cladding tshuab, ultra-siab ceev laser cladding tshuab muaj ntau yam zoo nyob rau hauv kev npaj ntawm nto tiv thaiv txheej, uas yog feem ntau xav txog nyob rau hauv lub txheej macroscopic zoo, sab hauv microstructure ntawm txheej, dilution tus nqi thiab hais txog.
Los ntawm cov txheej txheem macroscopic zoo, qhov roughness ntawm txheej txheej npaj los ntawm ultra-siab ceev laser cladding tshuab yog qis dua, thiab sab hauv ntawm txheej yog ntom thiab sib xws. Qhov saum npoo ntawm txheej txheej npaj los ntawm ultra-high-speed laser cladding tshuab yog smoother, thiab nws Ra tuaj yeem tsawg dua 10 μm, tsawg dua 10% ntawm cov pa laser cladding, uas tuaj yeem txo tus nqi ntawm kev kho deg tom ntej. Tsis tas li ntawd, lub ultra-high-speed laser cladding txheej nthuav tawm ib daim ntawv zoo li domino sib tshooj, uas tuaj yeem txo qhov kev sib nrig sib cuam tshuam ntawm cov matrix thiab txheej thiab txo qhov tsis xws luag xws li qhov thiab cov kab nrib pleb hauv txheej.
Nyob rau hauv cov nqe lus ntawm txheej microstructure, txheej txheej nplej npaj los ntawm ultra-siab ceev laser cladding tshuab yog me me thiab sib npaug. Lub microstructure ntawm ultrahigh-speed laser cladding txheej yog zoo ib yam li cov pa laser cladding txheej, uas yog tsuas yog tsim los ntawm dendrites. Txawm li cas los xij, vim qhov ceev ceev scanning ntawm ultrahigh-speed laser cladding technology, txheej txheej muaj qhov txias txias thiab supercooling degree thaum lub sij hawm solidification, ua rau cov nplej ntawm EHLA ntau me dua li ntawm CLA.
Nyob rau hauv cov nqe lus ntawm kev pab cuam, lub txheej npaj los ntawm ultra-high speed laser cladding tshuab muaj kev pab cuam zoo dua thiab kev pab lub neej ntev. Ntau cov kev tshawb fawb tau pom tias qhov kev tiv thaiv corrosion thiab hnav tsis kam ntawm cov txheej txheej npaj los ntawm ultra-siab ceev laser cladding tshuab yog ntau dua li ntawm cov substrate, thiab zoo dua li cov pa laser cladding txheej. Qhov no feem ntau yog vim qhov me me dilution tus nqi ntawm EHLA txheej (< 4%), which can maximize the excellent abrasion resistance of the cladding material.
Yog li ntawd, ultra-high ceev laser cladding tshuab yog suav hais tias yog qhov zoo tshaj plaws nto txheej tshuab los hloov electroplating nyuaj chromium, uas yog ib tug npaum thiab ntsuab cov ntaub ntawv nto ua technology thiab muaj dav daim ntawv thov prospects.
