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.
Keywords:
laser cladding, sliding indentation, wear track
