Daim ntawv thov ntawm Picosecond Laser hauv Kev Kho Mob Ntaus Khoom Siv
Laser yog qhov tsim tawm zoo ntawm xyoo pua 20. Nws tau hailed li" rab riam ceev tshaj plaws,"" lub teeb ci ntsa iab tshaj plaws," thiab" lub tshaj plaws yog kav." Kev hais lus ntawm kev thov laser hauv kev kho mob kev lag luam, tib neeg feem ntau xav txog laser ua ib txoj hauv kev ua tiav kev ua haujlwm ntawm kev tshem tawm quav, tattooing, tshem tawm qhov hnoos qeev, tshem tawm cov plaub hau thiab tawv nqaij rov qab los hauv kev lag luam kev zoo nkauj. Txawm li cas los xij, lasers muaj kev lag luam loj heev rau cov khoom siv kho mob.
Nyob rau hauv kev kho mob ntaus ntawv ua ntaub ntawv sau npe, tsoos ua txoj kev, xws li ntshav txau, sintering, thiab electrochemical deposition, yog tsis haum rau cov kev ntawm biomaterial kho mob pab kiag li lawm vim hais tias ntawm lawv cov qib high kub, siab acid, thiab siab alkali ua tej kev kawm.
Hauv kev sib piv, ultrashort-mem tes laser micromachining muaj qhov zoo ntawm kev ua txias, kev siv hluav taws xob tsawg, kev puas tsuaj me me, kev ua haujlwm siab, thiab nruj qhov chaw hauv 3D chaw, thiab muaj daim ntawv thov zoo nyob hauv kev ua cov cuab yeej siv kho mob.
Cov cuab yeej siv kho mob feem ntau muaj cuab kav tawv taub hau, caj pas pob taws, thiab lwm yam. Lawv cawm tau txoj sia nyob hauv tus kws kho mob' s zoo tes thiab coj lub neej tshiab rau cov neeg suav tsis txheeb.
Koj puas pom lawv los ntawm ntau yam ze?
Los ze zog -
Ntau ze zog -
Koj yuav pom ib txoj kev npliag, me, ob-kab kev cai uas yuav tsum tsis txhob saib dhau. Nws muaj ib qho tseem ceeb Hoobkas ntaub ntawv thiab yog ib qho tseem ceeb ntawm txoj kev cov khoom traceability.
Npav rau stainless steel phais seev yog ib tug raug daim ntawv thov ntawm lasers nyob rau hauv cov kev kho mob ntaus kev lag luam. Cov cuab yeej siv phais ua cov cuab yeej siv kho mob, kos cim yog qhov tseem ceeb ntawm nws txoj kev ua khoom lag luam thiab kev tsim khoom, feem ntau yuav tsum kos tus lej, sau ntawv, ob-kab kev cai, tuam txhab npe thiab lwm yam ntaub ntawv. Vim tias qhov tshwj xeeb hauv nws qhov kev siv ib puag ncig, muaj qhov siab xav tau rau kev kos, thiab nws yuav tsum muaj ntau yam zoo heev xws li anti-corrosion, anti-passivation, anti-autoclave thiab ua noj ua haus.
Ntawm no, peb siv cov lasers sib txawv (fiber ntau laser, UV nanosecond laser, infrared picosecond laser) los kos lub cim stainless hlau passivation txheej kom paub tseeb cov tshuaj tiv thaiv corrosion.
Los ntawm lub xeem pom:
Hauv cov txheej txheem kev kos ntawm lub fiber laser, tshav kub cuam tshuam cheeb tsam yog qhov loj, thiab cov hlau tsis xeb txheej txheej tau raug puas ntsoog, ua rau muaj qhov tshwm sim ntawm xeb hauv kev ntsuas ntsev txau.
Ultraviolet nanosecond laser muaj cov nyhuv ntawm" txias ablation" ;, tab sis nws cov ntsiab mechanism rau cov khoom tshem tawm ua yog tseem thermal ablation. Yog li ntawd, lub cim tseem ua rau lub stainless steel passivation txheej yuav tsum tau muab rhuav pov tseg, ua rau xeb nyob rau hauv lub ntsev tsuag xeem.
Infrared picosecond npav Vim tias nws cov cim txias ua haujlwm mechanism, stainless hlau passivation txheej tsis puas thaum lub cim txheej txheem. Los ntawm kev ntsuam xyuas ntsev txau cov tshuaj tiv thaiv, kev txhim kho qhov corrosion ntawm infrared picosecond cim yog qhov sib piv ntawm qhov ntawm cov hlau stainless substrate nws tus kheej.
Hauv kev ruaj ntseg tseem ceeb hauv kev kho mob niaj hnub no, cov khoom siv kho mob zoo yog tsis muaj lub siab xav ua kom pom tseeb ntawm cov neeg.
Infrared picoseconds tau muab coj los ua cov khoom haum rau cov khoom siv kho mob. Infrared picosecond npav muaj qhov zoo dua anti-corrosion kev ua tau zoo thiab paub dua. Nws tuaj yeem tswj lub zoo siab ntawm qhov sib txawv ntawm cov ces kaum thiab ntse ntug. Nyob rau tib lub sijhawm, cov khoom siv tshuaj phais yog ua los ntawm stainless hlau. Lub complex passivation theem yog tsis yuav tsum tau nyob rau hauv lub npav, uas muaj peev xwm txo tau cov ntau lawm txheej txheem thiab txo nqi.
Nyob rau hauv lub ntsej muag ntawm tus nruam deepening ntawm cov ntse raug kev lag luam, lasers, raws li tus siab heev ua txoj kev, ua si ib tug tshwj xeeb kom zoo dua nyob rau hauv kev kho mob ntaus npav daim ntaub ntawv. Laser-pab kho mob ntaus ntawv ntau lawm yog kev ruaj ntseg thiab ntau txhim khu kev qha, uas tsis muaj" caj npab" rau strike, thiab nws tiv thaiv cov neeg' s lub neej thiab noj qab haus huv.
