Abstract
At the paper is considered chemical composition and features of structure of samples of Ni-based
alloy obtained by direct laser method deposition at the different operating parameters. The range of
250 W to 1500 W of laser power was applied during deposition. Composition of starting powders
was obtained by scanning electron microscope. Light microscopy showed the cast structure with
transition serial tracks from laser beam. The maximum thickness of samples wall and the maximum
track thickness with homogeneous structure were reach at 1500 W. A particles of starting powder
were found at the structure at the minimum laser power (250 W). Minimum thickness of the defect-
free sample wall was formed with a power of 500 W.
