Wear processes of NP turbine blades and evaluation of selected properties of Stellit Co-6 top surface produced by PTA multilayered plasma method, and incremental laser were analyzed, including LENS method on alloy steel X22CrMoV12-1. The topography of the worn blade surface was observed. Regenerative quality of weld overlays in cross section using Keyence optical microscope was recorded. We were looking for welding defects in padding welds. The usefulness of applied methods has been confirmed. “The work was cofinanced by the European Regional Development Fund, Contract No POIG 01.04.00-24-101/13 signed between National Center for Research and Development and ZRE Katowice S.A.
