AB  - The effects of TEA CO2 laser radiation on AISI 420 stainless steel and formed surface structures are studied. The laser energy density of 45.0 J/cm(2) has modified the target surface. Qualitatively, the modifications of AISI 420 steel can be summarized as follows: change of color after action of one laser pulse; central zone of interaction in crater like form and periphery zone of interaction (for more than 10 laser pulses); appearance of grainy features and ablation rate of near 4 rim per laser pulse (action of 400 laser pulses); hydrodynamical effects like resolidified rim and droplets.

AB  - Pulsed carbon-dioxide (TEA CO2) laser, among other, is suitable for ablation of hard ceramic coatings (HCC). HCC, deposited on steel substrate, can be used for tools and machine parts protection. The roughness and thickness of HCC are commonly measured by a profilometer. Data obtained with diamond tip usually give real 2D surface profile. A 3D topography of the surface can be obtained with this procedure, too. The results of profilometric analysis including 3D visualization, using a Taylor-Hobson Talysurf 2 profilometer, of laser ablated area (especially craters) are presented in this work. The following HCC were studied: TiN, CrN, CrON, as well as stainless steel wafer; all of them were surface ablated by pulsed TEA CO2 laser. The applied profilometer analysis describes effects of laser ablation well and it would be supplement to the results obtained by microscopic analysis.

AB  - The interaction of a transversely excited atmospheric (TEA) CO2 laser with chromium oxynitride (CrON) coating deposited on a AISI 304 steel substrate was considered. The results have shown that CrON was surface-modified by the laser beam of 45 J/cm(2) energy density. The energy absorbed from the TEA CO2 laser beam was partially converted into thermal energy, which has generated a series of effects such as melting, vaporization of the molten material, and shock waves in the vapor and in the solid. Morphological manifestations on the CrON coating surface can be summarized as follows: non-uniform features with ablation and appearance of crater-like form (central zone of interaction); appearance of three damaged areas and presence of hydrodynamic effects with resolidified droplets (periphery zone of interaction). In case of applied energy density the interaction of laser radiation with CrON has been always followed by plasma creation in front of the coating.
