Lasersko navarjanje nitriranega orodnega jekla : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoLenaršič, RokDiplomska naloga obravnava poroznost lasersko izdelanih navarov na površinah nitriranih orodij. Naloga zajema pregled literature na teme laserskega varjenja in navarjanja ter odpravljanja poroznosti ... pri navarjanju nitriranih površin. Izdelan je načrt eksperimentov laserskega navarjanja ob uporabi dodajnih materialov z različno vsebnostjo titana, ki naj bi preprečeval nastanek poroznosti. Na vzorcih so bili izdelani obrusi in na njih narejena optična mikroskopija, mikroskopija SEM in analiza kemične sestave. Ugotovili smo, da na količino poroznosti vpliva globina pretalitve osnovnega materiala in količina titana v dodajnem materialu. Poroznost v zvaru smo zmanjšali pod 1 % celotne površine zvara s 5,87 % titana v dodajni žici. Rezultati kažejo, da lahko ob primerni izbiri parametrov in tehniki varjenja podobne rezultate dosežemo že z več kot 0,6 % titana v dodajnem materialu.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
