AB  - The effects of UV nanosecond laser pulses on multilayer CrN/(Cr,V)N coatings were studied. In the experiment laser irradiation was performed in air at 248 nm wavelength and pulse duration of 25 ns. The surface composition and microstructure was analyzed depending on the initial content of vanadium in the coatings and number of accumulated laser pulses at a fluence of 0.17 Jcm-2 . Most of the absorbed laser energy was rapidly transformed into heat, producing intensive modifications of the composition and morphology of the multilayer structure.The result has shown that concentration of metallic components was homogeneously distributed inside the coatings. However, on the surface and in the sub-surface regions the contents of Cr and V were decreased due to oxidation. The composition and thickness of created mixture of oxides Cr2O3 and V2O5 depend on the number of laser pulses and initial V content. Laser induced surface morphology changes of the multilayer CrN/(Cr,V)N coatingswere registered at the irradiation areas: (i) grainy structures at peripheries, (ii) cracks and (iii) irregular closed shapes in the center.
