AB  - The paper presents a study on the surface modifications of nickel based superalloy Nimonic 263 induced by laser shock peening (LSP) process. The process was performed by Nd3+:Yttrium Aluminium Garnet (YAG) picosecond laser using the following parameters: pulse duration 170 ps; repetition rate 10 Hz; pulse numbers of 50, 100 and 200; and wavelength of 1064 nm (with pulse energy of 2 mJ, 10 mJ and 15 mJ) and 532 nm (with pulse energy of 25 mJ, 30 mJ and 35 mJ). The following response characteristics were analyzed: modified surface areas obtained by the laser/material interaction were observed by scanning electron microscopy; elemental composition of the modified surface was evaluated by energy-dispersive spectroscopy (EDS); and Vickers microhardness tests were performed. LSP processing at both 1064 nm and 532 nm wavelengths improved the surface structure and microhardness of a material. Surface morphology changes of the irradiated samples were determined and surface roughness was calculated. These investigations are intended to contribute to the study on the level of microstructure and mechanical properties improvements due to LSP process that operate in a picosecond regime. In particular, the effects of laser wavelength on the microstructural and mechanical changes of a material are studied in detail.

AB  - Prikazano tehničko rešenje se primenjuje za poboljšanje mehaničkih osobina delova izrađenih od austenitnih materijala, pre svega superlegura nikla, koji se koriste za rad na povišenim temperaturama i pritiscima. Visoke radne temperature i pritisci zahtevaju što veću otpornost na zamor i koroziju, bolje mehaničke osobine, i osobine i strukturu površinskog sloja. Uvođenjem definisanih parametara laserske površinske obrade, odnosno optimizacijom parametara, postižu se optimalni rezultati u pogledu mikrostrukture, površinske morfologije i topografije, tvrdoće, a time i na osobine materijala: dinamičku čvrstoću, koroziju, mehaničke osobine i drugo. Oblast primene datog tehničkog rešenja se odnosi pre svega na avioindustriju, automobilsku industriju i energetiku, ali se data rešenja mogu uspešno primeniti i u nuklearnoj industriji.
