Iron base superalloy N-155 samples have been cut from the turbine blade which had been exposed to elevated pressure and temperature during its longtime service. The samples have been irradiated with pulsed laser beam, observed with scanning electron microscopy (SEM) and analysed by energodispersive spectrometry (EDS). The range of implemented beam parameters for which two types of treatments - mechanical and thermo-mechanical occurred, has been determined. Vickers micro hardness tests have shown the increase in micro hardness after laser treatment.
