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.
