The wear resistance of Ni-Cr-B-Si-C coatings 
after laser treatment with a doping covering under dry friction conditions 
has been investigated. The microstructure of coatings after fusion 
by a gas burner and a laser beam and the roughness and waviness parameters 
of the friction surfaces before and after wear have been investigated.
