Abstract. The sliding indentation test have good results for characterizing metals and alloys, polymers, ceramics, composites and a great range of coatings, and often it is connected with wear tests and modeling and simulation techniques. This paper presents research results on several multi-layer claddings achieved by powder injection of Ni alloy from the Ni-Cr-B-Fe-Al system, in the bath melt by CO2 laser in continuous wave. The comparisons of the geometrical characteristics of the different digital depth profiles confirm the better scratch behavior of the laser cladding layers.
