Nrog rau kev vam meej ntawm tib neeg thiab kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, cov khoom siv hlau tau siv ntau thiab ntau dua hauv kev lag luam, kev ua liaj ua teb, thiab ntau yam kev lag luam ntawm tib neeg lub neej, thiab lawv kuj tsim muaj txiaj ntsig zoo rau tib neeg. Hlau yog ib chav kawm ntawm cov khoom uas ci ntsa iab (uas yog, xav pom lub teeb pom kev zoo), malleable, thiab ua cua sov thiab hluav taws xob. Hlau yog feem ntau siv hauv lub neej. Nws yog ib qho tseem ceeb heev thiab feem ntau siv hauv kev lag luam niaj hnub no. Nws tuaj yeem ua tau me me li lub raj mis lossis lub taub hau, lossis loj npaum li lub tsheb, lub dav hlau, lossis lub nkoj… Los ntawm cov khoom siv hlau niaj hnub, kev tsim cov cuab yeej hlau, lub thawv thiab cov thawv ntim hlau tsim, cov hlau tsis muaj steel thiab cov khoom zoo sib xws, shipbuilding thiab marine engineering manufacturing, thiab lwm yam.
Cov ntaub ntawv hlau raug puas tsuaj los ntawm qhov kev txiav txim ntawm qhov nruab nrab ib puag ncig, uas yog hu ua hlau corrosion. Hlau xeb yog feem ntau hom corrosion. Hlau corrosion tshwm sim muaj ntau heev, xws li xeb ntawm cov khoom hlau, cov pob dawb ntawm cov khoom siv txhuas, patina ntawm cov khoom siv tooj liab, blackening ntawm cov khoom siv nyiaj, thiab lwm yam, uas tag nrho yog cov hlau corrosion.
Thaum lub sij hawm corrosion, tshuaj lom neeg los yog electrochemical multiphase cov tshuaj tiv thaiv tshwm sim ntawm qhov sib txuas ntawm cov hlau, ua rau cov hlau hloov mus rau hauv lub xeev oxidized (ionic). Qhov no yuav txo tau cov cuab yeej cuab tam xws li lub zog, plasticity, thiab toughness ntawm cov ntaub ntawv hlau, rhuav tshem cov geometry ntawm cov hlau Cheebtsam, nce hnav ntawm qhov chaw, deteriorate hluav taws xob thiab kho qhov muag lub cev lub cev, shorten lub neej kev pab cuam ntawm cov khoom, thiab txawm ua rau raug xwm txheej. Yog li ntawd, kev tshem tawm xeb yog ib qho tseem ceeb ua ntej kom ua haujlwm zoo.
Qiangyuan Laser tau cog lus rau kev tshawb fawb thiab kev tshawb fawb ntawm laser tu tshuab. Cia siab rau lub zog tshawb fawb kev tshawb fawb platform ntawm Shandong Academy ntawm Sciences, Qangyuan Laser tau tam sim no tsim cov kev sib tw tseem ceeb hauv kev tu laser. Nws muaj ntau tshaj 10 hom ntawm cov khoom siv no thiab tau txais ntau dua 50 daim ntawv tso cai thev naus laus zis.
Raws li lub xeev laser lub koom haum kev ua tau zoo hloov pauv txoj haujlwm, pab pawg tau sau ntau xyoo ntawm kev tsim cov thev naus laus zis thiab tau ua suav tsis txheeb tu thiab kuaj kev sim nyob rau theem pib. Tam sim no, lub tuam txhab laser xeb tshem tawm tshuab yog paub tab heev. Cov cuab yeej tsim kho laser tau tsim muaj kev ua haujlwm ruaj khov, ua tiav qhov ntsuas qhov ntsuas tsis zoo, thiab kev ua haujlwm yooj yim thiab meej. Raws li kev tiv thaiv zoo ntawm cov hlau substrate, nws tuaj yeem ua tiav qhov nyuaj thiab meej tu ntawm cov ntaub ntawv nyuaj. Nws tau ua tiav pab ntau lub tuam txhab ua tiav qhov kev hloov pauv ntawm kev tu ib txwm muaj kuab paug siab. Kev hloov pauv mus rau kev siv thev naus laus zis thiab ib puag ncig kev nyab xeeb ntsuab tu tau ua rau cov khoom siv rov ua dua tshiab thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv.
Laser tu tsis tsuas yog ntxuav cov hlau xeb, tab sis kuj tseem muaj roj, xim, thiab lwm yam organic los yog inorganic tebchaw ntawm cov hlau nto tuaj yeem ntxuav tau sai thiab zoo. Tsis tas li ntawd, lasers tuaj yeem siv los ntxuav cov ntoo, pob zeb, cov khoom sib xyaw, thiab cov phab ntsa uas muaj nyob hauv lub neej thiab kev lag luam. Rau precision pob zeb carvings thiab ancient kab lis kev cai relics, laser tu muaj qhov zoo zoo piv nrog tsoos tu tshuab. Ntawm qhov tod tes, qhov tob thiab thaj tsam ntawm kev ntxuav laser tuaj yeem tswj tau los ntawm kev hloov kho kom zoo dua qub; ntawm qhov tod tes, lub laser nws tus kheej yuav tsis Lub pob zeb carvings coj kev puas tsuaj thiab muaj kuab paug rau lawv tus kheej thiab ib puag ncig ib puag ncig.
