Povzetek

V diplomski nalogi so opisani in predstavljeni rezultati eksperimentalne analize laserskega pretaljevanja magnezijevih zlitin AZ80 in ZK60. Vzorce smo lasersko pretalili z in brez dovoda zaščitnega plina, s tem da, smo lahko naredili primerjavo lasersko površinskega sloja vzorca z in brez dovoda zaščitnega plina.

Sekundarni naslov: Laser remelting of magnesium alloys ZK60 and AZ80
Sekundarni povzetek: The diploma thesis describes and presents the results of experimental analysis of laser remelting of magnesium alloys AZ80 and ZK60. The samples were laser remelted with and without shielding gas supply, so that we could compare the laser surface layer of the sample with and without shielding gas supply. As part of the diploma thesis for optimal laser remelting, it was necessary to set such parameters that the sample under the laser beam melts but does not evaporate. The selected parameters were thus determined by preliminary tests, where we obtained the optimal depth and width of the remelted layer. After laser remelting, we performed metallographic analysis of the samples under a microscope to ascertain their microstructure. Also, with the help of analysis under a microscope, we selected the optimal laser conditions to achieve the desired quality of the remelted surface layer. Then, after metallographic analysis, the prepared samples were used to measure the microhardness and to measure the dimensions of the molten layer. Then, one part of the sample was laser-melted by covering the traces, and it was used to analyze the surface roughness and measure the corrosion resistance. The aim and purpose of the diploma thesis was to determine the optimal conditions for laser remelting of magnesium alloys AZ80 and ZK60. We also wanted to find out what effect laser remelting has on their microstructure, microhardness, roughness and corrosion resistance, under different processing conditions.
