Dab tsi yog Picosecond laser?
Picosecond lasers xa mus rau lasers nrog ib tug mem tes dav ntawm picoseconds. Lawv muaj cov yam ntxwv ntawm kev kho cov rov ua dua cov zaus thiab lub zog siab siab. Nrog rau cov kev nce qib tshiab hauv txhua-lub xeev (DPS) Laser thev naus laus zis xyoo tsis ntev los no, kev thov cov kab txuas sai tshaj plaws hauv ntau cov kab kev lag luam.
Nyob rau hauv 2015, Asmeskas Cov Khoom Noj Khoom Haus thiab Tshuaj Siv (FDA) siv cov khoom siv khomob (UDI) Cov lej cim qhia npe. UDI yuav tsum muaj cov qauv hauv qab no:
- siab sib xws thiab tob dub;
- nyob ruaj khov, tsis-fading, corrosion-resistant;
- tshuab-readable;
- ntiav khij, me me rau kev zam kom tiv thaiv cov kab mob sib txuam.
Laser Marking thev naus laus zis siv nyob rau hauv cov cuab yeej siv kho mob kom ua tiav xws li cov cim cim kev lag luam, suav tus lej cim thiab cim kev sib tw.
Yog li, puas yog Picosecond laser tseem muaj kev ua tau zoo heev hauv kev xaiv siab? Peb simulated lub chaw kho mob heev los sim cov hlau uas tsis muaj hlau tom qab picosecond laser cim.
304 Stainless hlau yog feem ntau hom stainless hlau, txuas tau dav hauv kev lag luam, khoom noj, cov ntaub ntawv tsim kho, tsev. Peb noj 304 stainless hlau ua ib qho piv txwv thiab siv cov khoom siv picosecond infrared laser (jpt-ps-} {4}}) los khij saum npoo ntawm 304 stainless hlau hauv dub. Cov hlau stainless hlau yog raus hauv ib qho kev daws teeb meem ntawm ib puag ncig, yog li sim cov corrosion tsis kam ntawm cov cim dub. Cov txheej txheem sim yog raws li hauv qab no:
Peb piv cov ntawv stainless hlau tom qab jpt-ps-ps-ps-{2}} tus nqi hloov pauv me ntsis tom qab kev daws teeb meem hauv nacl rau 72 teev
Cov saum npoo ntawm xeb hlau daim ntawv tom qab soaking thiab pom, thiab nws tau pom tias cov xim dub cim los ntawm jpt-ps-} tsis txhob poob lossis ploj mus rau 72 teev
Thaum stainless hlau yog irradiated los ntawm doger zoo tib yam, lub thermal effect yog hom. Qhov ntau ntawm cov oxidation oxidation tau siv los tsim cov txheej dub oxide nyias nyias kom ua tiav lub hom phiaj ntawm kev khij cov xim dub. Ntawm ib sab tes, ntau cov khoom siv oxidation yuav ua rau tsis txaus lossis tsis xwm yeem dub. Ntawm qhov tod tes, cov txheej oxide feem ntau yuav poob lossis tawm tsam cov kua qaub, yog li rhuav tshem qhov corrosion tsis kam ntawm lub stainless hlau nws tus kheej. Ultrashity mem tes (picosecond) lasers tuaj yeem nqus cov roj av (raws li muaj kev tiv thaiv lub teeb rau ntawm cov hlau tsis muaj zog tuaj yeem khaws cia.
