Črno, belo in barvno označevanje z nanosekundnim vlakenskim laserjem : zaključna naloga univerzitetnega študijskega programa I. stopnje StrojništvoŠpan, RokLaserji so na področju industrije vedno bolj uporabljeni in izpodrivajo konvencionalne načine obdelave površin. En izmed pomembnih namenov njihove uporabe je tudi označevanje oz. dekorativno barvanje ... materialov, saj je postopek relativno hiter in poceni. V nalogi se ukvarjamo z iskanjem optimalnih parametrov za nastanek določenih barv na nerjavnem jeklu in pojasnimo, zakaj do nastanka barve sploh pride. Vzorce smo označevali z laserskim sistemom, ki je sestavljen iz nanosekundnega vlakenskega laserja, skenirne glave z F-theta lečo z goriščno razdaljo 163mm, pozicionirnega sistema in programskega grafičnega vmesnika SCAPS SAMLight. Rezultate smo ovrednotili pod optičnim mikroskopom, eksperimente pa smo v celoti izvedli na vzorcih nerjavnega jekla AISI 304. Na koncu naloge smo lasersko izdelali tudi barvno fotografijo. Z eksperimentiranjem smo uspeli določiti parametre za izdelavo bele in črne oznake ter sledečih barvnih odtenkov: rožnatega, vijoličnega, oranžnega, rumenega, modrega in zelenega. Pokazali smo tudi, kako povprečna moč bliskov, hitrost vodenja snopa, frekvenca in oblika bliskov ter razmiki med linijami, s katerimi označujemo, vplivajo na nastanek barvnih odtenkov. Poleg tega smo pokazali, da ima pri laserskem barvanju pomembno vlogo kot, pod katerim vodimo laserski snop.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
