Lasersko obarvanje kovin : zaključna naloga univerzitetnega študijskega programa I. stopnje StrojništvoMarušič, Benjamin, strojnikLasersko obarvanje kovinskih površin predstavlja pomembno estetsko dodelavo tradicionalnih laserskih tehnik, ki vključujejo najrazličnejše enobarvne postopke graviranja. Največje zanimanje za ... tovrstne postopke se kaže v gradbeni, kemijski, avtomobilski in elektro industriji. Nastanek barve na površini je rezultat nadzorovane površinske oksidacije, ki se zgodi med postopkom interakcije laserske svetlobe s kovino. Proces je odvisen od številnih parametrov, zato se v zaključni nalogi posvečamo raziskovanju vpliva laserskih parametrov v zraku (brez prisotnosti druge plinske atmosfere) na nastanek različnih barv. Uporabili smo označevalni nanosekundni Nd:YAG laser in različne parametre preizkusili na aluminiju, bakru, nerjavnem jeklu in titanu. Najboljše rezultate smo dosegli na titanu, kjer smo dokazali, da lahko zgolj s spreminjanjem povprečne moči in hitrosti označevanja dosežemo dokaj pisano barvno lestvico. Rezultate smo evalvirali z optičnim mikroskopom in inovativnim pristopom z uporabo spektrometra. S pomočjo mikroskopa smo ugotovili, da posamezen barvni odtenek ni zgolj zmes ene barve, temveč predstavlja vsoto %osnovnih% barv, ki se nahajajo znotraj posameznega laserskega kraterja. Skupek kraterjev tvori lasersko sled, več sledi pa da na koncu eno ali več barvni laserski kvadratek. Primerjava na oko izbranih barv na titanu z ustreznimi RGB in CMYK barvnimi odtenki pri različnih intenzitetah potrjuje ujemanje njihovih spektrov.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
